Routing is now +header-only at the gateway root — `api.riotpiao.com` itself is the single entry +point, no dedicated sub-path. New backend services onboard via a CRD the gateway +consumes directly, not via hand-written Go switch cases. + +--- + +## Context + +Most of the original hybrid design was aspirational — it didn't exist in code. This +revision reflects decisions made while reviewing the repo against the actual state: +`internal/auth/` was empty, `s3`/`sqs`/`iam` didn't exist as handlers, and only a +body-action `POST /workflow` endpoint was real. Four extensions were decided: +CRD-driven service onboarding, `X-Resource`-based REST verbs replacing body actions, +unified JWT auth (bearer token or service-account password, one validation path), and +blind 5xx retry. + +Known constraints, and how these decisions land on them: +- Rule G2 (originally specced in the now-retired `tasks/6.2-kubernetes-manifests.md`, + deleted 2026-08-25 since Phase 6 shipped and is live in-cluster) mandated **no + ServiceAccount/RBAC** on the gateway pod, and routes loaded from a git-sourced + ConfigMap with a pod roll on every change. The gateway pod now consumes the CRD + directly — no separate operator/controller pod. This is a deliberate, acknowledged + supersession of G2 for this one narrow purpose: the existing `api-gateway` + `ServiceAccount` (already bound to the pod at `k8s/rbac.yaml:1-7`, currently with + zero Role — see `k8s/rbac.yaml:9-10`'s own comment "the gateway has no k8s API + access") gains a namespace-scoped `Role` limited to read-only access on one CRD, + defined in this same repo and synced by the existing `api-gw` ArgoCD Application + (`homelab/k8s/argocd/apps/55-api-gateway.yaml`) — no new repo, no new Application. + Static ConfigMap-sourced routes keep the existing roll-on-change behavior; + CRD-sourced routes update live in-process instead (see §1). +- Retired `kmsvc.io` `TemporalWorker`/`Queue` CRD (`homelab/k8s/apps/messaging/queue-crd/`, + controller in the separate `kmsvc-manage` repo) broke via an uncleared finalizer and + RBAC rules that drifted out of sync with the CRD's resources + (`temporalworkers.kmsvc.io is forbidden ... at the cluster scope`). Cluster-scoped + RBAC, RBAC/CRD drift, and finalizer complexity are explicitly avoided this time — + this CRD is namespace-scoped (`api` only) and read-only from the gateway's side. + +--- + +## 0.

Service onboarding (new backend service = code change vs. YAML) + +### Existing System +- No CRD, no controller, no generic service registry anywhere in either repo. +- Adding a service today means: write a new Go handler, add a `switch` case, redeploy + the gateway image. Only `workflow` exists (`internal/temporal/handler.go`); `s3`, + `sqs`, `iam` don't exist in code at all. +- `internal/config/config.go` + `loader.go` load only static, hand-edited route config + from the ConfigMap already live per Phase 6 (`k8s/configmap.yaml`) — no per-service + schema, no CRD. + +### Future System +New CRD **`ServiceAdapter`** (`gateway.riotpiao.com/v1`, namespace-scoped to `api` +only — deliberately *not* cluster-scoped, unlike the retired CRD). Named for what it +actually does — adapts an in-cluster service to the gateway's +`X-Service`/`X-Resource` contract — rather than a generic "Definition". + +**No separate operator pod.** The API gateway pod itself consumes the CRD directly: it +runs a `client-go` informer against `ServiceAdapter` in namespace `api` and keeps an +in-memory route registry that adds/updates/removes entries as CRs change — no +ConfigMap render step, no restart-to-pick-up-changes, no second binary/Deployment/image +to build and operate. + +**Where the CRD is defined — this repo, not `homelab`.** Confirmed at +`homelab/k8s/argocd/apps/55-api-gateway.yaml:42-45`: the `api-gw` ArgoCD Application +already sources this repo's own `k8s` path directly (kustomize — Deployment, Service, +ConfigMap, RBAC, NetworkPolicy), auto-syncing on every push to `main`, wave 7. So the +CRD manifest is just another file in that same kustomization: new +`k8s/crd-serviceadapter.yaml`, added to `k8s/kustomization.yaml`'s `resources:` list. +When a new `ServiceAdapter` CR is introduced (i.e. someone commits a CR YAML for a new +service), ArgoCD syncs it through this same already-existing Application, and the +already-running `api-gw` pod's informer notices it and starts accepting +`X-Service: ` calls — no new Application, no new repo, no manual step in +`homelab` at all. Go API types back the CRD from +`apis/gateway/v1/serviceadapter_types.go` (new package, generates the CRD YAML via +`controller-gen`, same struct also used by the informer). + +`spec.auth.capability` is the default capability required for every resource on the +service. A method entry may override it with its own `auth.capability` — needed once +a service splits read vs. write access (see §6's `memory` adapter). No override means +inherit the spec-level default; `auth.required: false` at either level means no +capability check at all for that scope. + +**Example CR** (onboarding a hypothetical `postgres` service — no Go code, no image +rebuild, no manual gateway restart): + +```yaml +apiVersion: gateway.riotpiao.com/v1 +kind: ServiceAdapter +metadata: + name: postgres + namespace: api +spec: + serviceName: postgres # matches X-Service: postgres + upstream: + url: http://kmsvc-postgres-helper.sqs.svc.cluster.local:8080 + timeoutSeconds: 10 + auth: + required: true + capability: postgres:access # checked against the caller's JWT claims + retryable: true # eligible for the blind 5xx retry middleware, §4 + resources: + - name: query # X-Resource: query + methods: + - verb: POST + upstreamPath: /v1/query + requestSchema: + fields: + sql: string + params: array + required: ["sql"] + responseSchema: + fields: + rows: array + - name: table + methods: + - verb: GET + upstreamPath: /v1/tables/{id} # {id} filled from the trailing path segment + - verb: DELETE + upstreamPath: /v1/tables/{id} +status: + phase: Ready + observedGeneration: 1 +``` + +Calling it once reconciled — straight to the gateway root, no dedicated sub-path: + +```bash +curl -X POST https://api.riotpiao.com/ \ + -H 'Authorization: Bearer ' \ + -H 'X-Service: postgres' \ + -H 'X-Resource: query' \ + -d '{"sql": "select 1"}' +``` + +**RBAC** — extend `k8s/rbac.yaml` in place (same file that already defines the +`api-gateway` `ServiceAccount` at lines 1-6, currently role-less per its own "the +gateway has no k8s API access" comment). A namespace-scoped `Role` (not `ClusterRole`), +read-only, nothing else — this is the entire RBAC footprint added to the gateway pod, +shipped in the same repo/PR as the CRD itself: + +```yaml +apiVersion: rbac.authorization.k8s.io/v1 +kind: Role +metadata: + name: api-gateway-serviceadapter-reader + namespace: api +rules: + - apiGroups: ["gateway.riotpiao.com"] + resources: ["serviceadapters"] + verbs: ["get", "list", "watch"] +--- +apiVersion: rbac.authorization.k8s.io/v1 +kind: RoleBinding +metadata: + name: api-gateway-serviceadapter-reader + namespace: api +roleRef: + apiGroup: rbac.authorization.k8s.io + kind: Role + name: api-gateway-serviceadapter-reader +subjects: + - kind: ServiceAccount + name: api-gateway + namespace: api +``` + +No `status`/`finalizers` verbs, no write access at all — the gateway only ever reads. +No new `ServiceAccount`, no new Deployment, no new container image. + +**Gateway-side consumer** — new `internal/serviceadapter/registry.go`: a `client-go` +`SharedInformer` on `ServiceAdapter` in namespace `api`, feeding an in-memory map keyed +by `spec.serviceName` that the `internal/serviceadapter` dispatcher (§2) reads on every +request. Add/Update/Delete informer callbacks update the map directly — a new +`ServiceAdapter` CR is live within the informer's resync/watch latency, no gateway +restart, no ArgoCD change beyond the existing auto-sync of this repo's `k8s` path. + +**Request/response validation** — `requestSchema`/`responseSchema` are not JSON +Schema. Deliberately a flat key→type map, author-facing (whoever writes the CR +specifies it, no JSON Schema knowledge needed): + +```yaml +requestSchema: + fields: + sql: string # one of: string | number | boolean | array | object + params: array + required: ["sql"] # optional; omit if every field is optional + strict: false # optional, default false — true rejects unlisted keys +responseSchema: + fields: + rows: array +``` + +One level deep only — `params: array` checks "is this an array," not what's +inside it. No enums, no formats, no nested field validation. Accepted limitation: +none of the adapters in this doc (postgres, workflow, iam, memory) need more than +top-level shape checking. + +**Extension forced by real upstream shapes (poimen-memory, §6):** the DSL above +only describes a top-level JSON *object*. `GET /memory/projects` returns a bare +array (`["poimen", ...]`), `GET /memory/query` returns an array of objects, and +`GET /memory/skills` returns objects with an explicit `"generated_from": null`. +Neither is expressible in the object-only form, so two additions, kept minimal +rather than backsliding toward full JSON Schema: + +```yaml +responseSchema: + type: array # top-level shape; default "object" if omitted + items: string # scalar array — every element must be this type +responseSchema: + type: array + items: + fields: # object array — one level deep INSIDE each item + level: string + sha256: string + score: number +responseSchema: + fields: + generated_from: { type: string, nullable: true } # long form only needed for nullable +``` + +Rule: a field written as a bare type string (`sql: string`) is shorthand for +`{type: string, nullable: false}`. `null` satisfies any field marked +`nullable: true` regardless of its declared type; a `null` on a non-nullable +field is a `type_mismatch`. Still one level deep — `items: { fields: {...} }` +does not itself accept a nested `items`. + +Validated in Go via `internal/serviceadapter/validate.go` (new, ~40 lines, no +external dependency): `json.Unmarshal` the body into `map[string]interface{}`, +check `Required` fields are present, check each present field in `Fields` against +its Go runtime type (`string`→string, `float64`→number, `bool`→boolean, +`[]interface{}`→array, `map[string]interface{}`→object), and if `strict: true` +reject any body key not listed in `Fields`. Compiled once per CR add/update in the +informer callback above, not per-request — the parsed `FieldSchema` struct is +stored directly in the same registry map entry as the route. + +Request-side violations are enforced: 400, RFC 9457 `problem+json`, body +`{type, title, detail, errors: [{field, reason}]}` where `reason` is one of +`missing`, `type_mismatch: want X got Y`, or `unknown_field` (strict mode only). +Response-side violations are **not** enforced — the response is forwarded to the +caller unchanged; a mismatch only emits a +`serviceadapter_response_schema_mismatch{service,resource}` metric and a log line. +Rationale: request validation is a trust boundary (external caller input); +response validation is contract-drift detection against our own upstream — turning +a backend field-shape typo into a caller-facing 502 does more harm than logging it. + +--- + +## 2. Request shape: body action vs. header verb + +### Existing System +- `internal/temporal/handler.go`: `POST /workflow` only, body is + `{action, namespace, payload}` (`RequestPayload` struct) — action dispatch happens + by reading and branching on the JSON body, not by header/method. +- `internal/server/router.go` dispatches purely by **path**: exact-matches + `/healthz`, `/readyz`, `/workflow`, `/workflow/health`, `/workflow/metrics`, and + falls through everything else (including `/v1/chat/completions`) to + `upstreamHandler`. There is no header-based dispatch anywhere in the router today. +- `s3`/`sqs`/`iam` bodies with `operation`/`action` fields, and a `/unified` sub-path, + were only ever prose in an earlier draft of this doc — never implemented, and now + dropped. + +### Future System +No new sub-path is introduced. `internal/server/router.go`'s `ServeHTTP` gets one new +branch, checked **before** the existing path switch: if the request carries an +`X-Service` header, dispatch straight to a new `internal/serviceadapter/router.go` +dispatcher, regardless of `r.URL.Path` (callers hit `https://api.riotpiao.com/` at the +root). `/v1/chat/completions`, `/v1/embeddings`, `/v1/rerank`, `/healthz`, `/readyz` +keep their existing path-based routing in `internal/proxy/router.go` — those never +carry `X-Service` and are matched first. `/workflow*` stays mounted during migration, +delegating internally to the same dispatcher, then gets removed once callers move to +header-based calls. + +Dispatch key becomes **`X-Service` header → adapter**, then **HTTP method + +`X-Resource` header → `{verb, upstreamPath}`** — e.g. `GET` to the gateway root + +`X-Service: iam` + `X-Resource: user` → list Authentik users. This replaces the body +`action`/`operation` field convention everywhere, not just for `iam` — so the +rewritten `workflow` adapter looks like: +- `POST X-Resource: workflow` → `START_WORKFLOW` +- `GET X-Resource: workflow/{id}` → `QUERY_WORKFLOW` +- `GET X-Resource: workflow` → `LIST_WORKFLOWS` +- `DELETE X-Resource: workflow/{id}` → `TERMINATE_WORKFLOW` +- `GET X-Resource: workflow/{id}/history` → `GET_WORKFLOW_HISTORY` +- Same pattern for new `s3` (`bucket/{key}`) and `sqs` (`queue/{name}/message`) + adapters — built fresh, since they don't exist in code today. + +`/v1/chat/completions`, `/v1/embeddings`, `/v1/rerank` in `internal/proxy/router.go` +are **unchanged** — local-LLM-only, no `X-Service` involvement. + +--- + +## 3. IAM access to Authentik + +### Existing System +- No `X-Service: iam` adapter in the gateway. +- Authentik admin API access exists today only client-side, in the Rust `core` CLI + (`/Users/rockliang/workplace/core/src/cmd/iam/*.rs`), which already calls + `{authentik_url}/api/v3/core/applications/`, `/api/v3/providers/oauth2/`, + `/api/v3/core/flows/`, `/api/v3/crypto/certificatekeypairs/` for apps/providers/flows + — confirmed at `core/src/cmd/iam/app.rs:136,160,191,205,219`. No users/groups/roles + coverage there, and none of it is reachable through the gateway. + +### Future System +New `internal/iam/handler.go` server-side adapter, reachable at the gateway root with +`X-Service: iam`, mapping `X-Resource` + method onto Authentik's `/api/v3/...` surface: + +| X-Resource | Method | Authentik endpoint | +|---|---|---| +| `user` | GET/POST | `/api/v3/core/users/` | +| `user/{id}` | GET/PATCH/DELETE | `/api/v3/core/users/{id}/` | +| `service-account` | POST | `/api/v3/core/users/service_account/` | +| `role` (group) | GET/POST | `/api/v3/core/groups/` | +| `permission` | GET/POST | `/api/v3/rbac/permissions/` | +| `flow` | GET | `/api/v3/flows/instances/` | + +This is additive to, not a replacement of, the `core iam` CLI subcommand — different +caller (server vs. local CLI), same upstream API. + +--- + +## 4. Auth: how a caller proves identity + +### Existing System +- `internal/auth/` is an **empty directory** — zero implementation. `tasks/` Phase 3 + (JWKS fetch/rotation, Bearer validation, Authentik service account, flag-gated + rollout, capability authorization) was retired 2026-08-25 — this doc is now the spec + for that work instead of those deleted task files. +- `kmsvc.riotpiao.com` (separate service) has an auth interceptor + (`kmsvc-manage/internal/api/interceptors/auth.go`, JWKS validation via + `lestrrat-go/jwx/v2/jwt`) but it's **never wired in** — `cmd/server/main.go` builds a + bare `grpc.NewServer()` (`kmsvc-manage/cmd/server/main.go:84`), and the REST surface + bypasses gRPC interceptors entirely even once fixed. Useful code to reference, not to + copy the deployment of. +- The `core` CLI already does human OIDC login (`core auth login` — device-code/OOB + against Authentik) and caches a token at `~/.cache/talos/authentik_id_token` + (`core/src/cmd/auth/mod.rs:336-338`) — a **different** token/cache than what §5 adds. + +### Future System +Implement in `internal/auth`, with two entry paths converging on one validated-JWT +middleware — no separate downstream logic per path: +1. **Bearer passthrough** — `Authorization: Bearer ` sourced from + `~/.talos/.riotpiao-auth` (written by `mwinit`, §5), validated against Authentik's + JWKS. +2. **Service-account password grant** — Authentik service-account username/password + exchanged for a JWT. Reuse the validation *logic* already written (but unwired) in + `kmsvc-manage/internal/api/interceptors/auth.go`, not its deployment config. + +Retry middleware (`internal/resilience/retry.go`, new) wraps every outbound upstream +call from the `internal/serviceadapter` dispatcher: **blind retry on any 5xx**, bounded +attempts with backoff, no idempotency-key gating — Temporal (and other backends) own +dedup on their side. `ServiceAdapter.spec.retryable` (default `true`) is the only +opt-out. + +--- + +## 5. `CLI-MWNINIT.md` (separate doc) + +### Existing System +The Rust `core` CLI (`/Users/rockliang/workplace/core`) has `core auth login` +(`src/cmd/auth/mod.rs`) for human OIDC device-code/OOB login, and a separate `core iam` +subcommand tree (`src/cmd/iam/`) for app/group/scope management.

These get CR entries below so the schema is defined once, but the +gateway-side task for each is **blocked on upstream**, not just on our own code — +see §7's status column. + +It also currently does its own auth: an `apikey:` header check, exact-match against a +stored key, implemented in the app itself +(`tasks/M3.5.1-http-server.md:36-39`) — independent of Kong, which its own +architecture diagram assumed sat in front but never actually required for this check +to work.

RBAC at Git Level + +```typescript +// Git hook can enforce RBAC locally +function canPushSecrets(token: JWT) { + const groups = token.groups; + + // Only k8s:secret-admin can push to secrets/ + if (!groups.includes("k8s:secret-admin")) { + return false; + } + + return true; +} +``` + +### 4. No Dependency on Authentik Being Up + +``` +If Authentik is temporarily down: + ✅ Developers can still push (JWT validates locally) + ✅ Works offline + ❌ With random tokens: push fails +``` + +### 5. Temporal Can Verify Tokens Locally + +``` +Temporal workflow (token rotation): + └─ Reads old token from K8s + └─ Decodes JWT: check exp field + └─ "Is this token about to expire?" + └─ Generate new token + +No API call needed to validate old token. +``` + +--- + +## Random Token Benefits + +### 1. Standard OAuth2 Practice + +``` +Random tokens are what most OAuth2 providers use: + ├─ Opaque (attacker doesn't know content) + ├─ Standard bearer tokens + └─ What Authentik probably generates by default +``` + +### 2. Immediate Revocation + +``` +If token is compromised: + └─ Delete it from Authentik + └─ All git pushes instantly fail + +With JWT: + └─ Token is still valid until exp time + └─ Attacker has until expiry +``` + +### 3. Smaller Size + +``` +JWT: ~500 bytes (base64 encoded) +Random: ~32 bytes (hex) + +Difference: + ✅ Slightly smaller in git metadata + ❌ But negligible for practical purposes +``` + +### 4.

Embedded RBAC +``` +With JWT: + Git hook reads groups from token + └─ Only k8s:secret-admin can push to secrets/ + └─ Enforced locally + └─ No additional database lookups + +With random token: + Git hook calls Authentik API twice + └─ Introspect token + └─ Fetch groups + └─ Slower +``` + +### 3. Audit Trail +``` +With JWT: + Git commit includes token claims + └─ User, groups, timestamp all in commit metadata + └─ Complete audit trail automatically + +With random token: + Git commit has only token + └─ Need to log token → user mapping separately + └─ Additional logging overhead +``` + +### 4. Temporal Token Rotation +``` +With JWT: + Temporal reads exp field + └─ "Token expires in 2 hours" + └─ No API call needed + +With random token: + Temporal calls Authentik API + └─ "Is this token still valid?" + └─ Network call needed +``` + +--- + +## How to Get JWT from Authentik + +### Option 1: OpenID Connect (Standard) +``` +Authentik already supports OIDC: + +Developer requests token: + $ curl -X POST https://authentik.../application/o/token/ \ + -d "grant_type=password&username=user&password=pwd&scope=openid profile groups" + +Response: + { + "access_token": "eyJhbGc...", ← JWT + "token_type": "Bearer", + "expires_in": 86400, + "id_token": "eyJhbGc..." + } +``` + +### Option 2: OAuth2 with JWT +``` +Authentik OAuth2 provider settings: + ├─ Enable: "Use claims-based access tokens" + ├─ Token claims: username, email, groups, preferred_username + └─ Signature algorithm: RS256 + +Result: Access token is now JWT instead of random. +``` + +--- + +## Implementation: SOPS + JWT + +```bash +# Developer gets JWT token from Authentik +$ token=$(oidc-client get-token) +$ echo $token # base64 encoded JWT, not random string + +# SOPS commits with JWT +$ export SOPS_TOKEN=$token +$ sops secrets/default/db-creds.enc.yaml +$ git add . && git commit -m "update" && git push + +# Git hook receives commit +$ git hook: +# 1.

Blacklist approach (store revoked JWTs) + └─ Git hook checks blacklist before validating + └─ But defeats purpose of stateless tokens + +3.

Authentik supports it natively +2. Git hook verification is instant (no API calls) +3. Embedded claims give you free audit trail +4. Works offline (resilient) +5. Perfect for homelab scale + +**Setup:** +1. Configure Authentik OIDC provider +2. Enable "Use claims-based access tokens" option +3. Add groups to token claims +4. Developers get JWT instead of random string +5. Git hook validates JWT locally (no API call) + +**Code example for git hook:** +```bash +#!/bin/bash +# .git/hooks/update (server-side) + +token=$(git log -1 --pretty=%B | grep "X-SOPS-Token" | cut -d' ' -f2) + +# Verify JWT signature +jwt verify $token --key /path/to/authentik/public.key + +# Decode and check groups +groups=$(jwt decode $token | jq .groups) +if [[ !

Action-Based Routing - -**Decision**: Use `"action"` field instead of path routing - -```json -// ✅ GOOD (chosen) -POST /workflow -{ - "action": "START_WORKFLOW", - "payload": {...} -} - -// ❌ NOT CHOSEN -POST /workflow/start -POST /workflows/executions/start -``` - -**Rationale**: -- Single endpoint for all operations -- Easier middleware/auth integration -- Cleaner error handling -- Future-proof for new operations - ---- - -### 3. Namespace as First-Class Field - -**Decision**: Include `namespace` in every request (not in URL path) - -```json -// ✅ GOOD (chosen) -{ - "action": "...", - "namespace": "production", - "payload": {...} -} - -// ❌ NOT CHOSEN -POST /workflow/production/start -``` - -**Rationale**: -- Namespace is runtime parameter, not structural -- Allows easy namespace switching in same request -- Consistent with Temporal SDK patterns -- Simplifies multi-tenant scenarios - ---- - -### 4. Pagination via Token - -**Decision**: Use opaque `next_page_token` for pagination (not offset) - -```json -{ - "action": "LIST_WORKFLOWS", - "payload": { - "page_size": 50, - "next_page_token": "opaque_token_from_previous" - } -} -``` - -**Rationale**: -- Matches Temporal's native pagination -- Handles distributed state better -- Prevents offset consistency issues -- More efficient for large datasets - ---- - -### 5. Filters as Map, Not DSL - -**Decision**: Use structured filters object (not string filter syntax) - -```json -// ✅ GOOD (chosen) -{ - "filters": { - "status": "RUNNING", - "workflow_type": "OrderProcessing", - "start_time_from": "2024-01-10T00:00:00Z" - } -} - -// ❌ NOT CHOSEN -{ - "filter": "ExecutionStatus = RUNNING AND WorkflowType = 'OrderProcessing'" -} -``` - -**Rationale**: -- Type safety (can validate fields) -- Better IDE support -- Easier to build dynamically -- Prevents filter injection attacks - ---- - -## 💡 TaskQueue Management Recommendation - -### The Problem - -TaskQueues in Temporal are: -- Created automatically when workers connect -- Managed by the cluster -- Hard to monitor without direct cluster access -- Critical for worker load distribution - -### The Options - -#### Option A: Full CRUD (NOT RECOMMENDED) -```json -{ - "action": "CREATE_TASK_QUEUE", - "payload": {"name": "custom_queue"} -} -``` -**Problems**: Can't actually create; only workers can; confuses users -

---- - -## 💡 Common Patterns - -### Extract chat response from workflow - -```python -response = requests.post("https://api.riotpiao.com/workflows", json={...}) -if response.status_code == 200: - result = response.json() - if result["status"] == "completed": - # For chat-and-embed - content = result["output"]["chat_response"]["choices"][0]["message"]["content"] - print(content) -``` - -### Extract embeddings from workflow - -```python -result = response.json() -if result["status"] == "completed": - embeddings = result["output"]["data"][0]["embedding"] - print(len(embeddings), "dimensional vector") -``` - -### Check for errors - -```python -result = response.json() -if result["status"] == "failed": - print("Error:", result.get("error")) -``` - ---- - -## 🎯 Performance Tips - -1. **Batch operations** - Use `batch-embeddings` instead of individual embedding calls -2. **Longer timeout for complex queries** - RAG pipelines may take 5-10 seconds -3. **Reuse embeddings** - Cache embedding results for repeated texts -4. **Async mode** - Use `wait: false` for non-blocking operations - ---- - -## 🆘 Troubleshooting - -**Q: Getting "connection refused" error?** -- Ensure gateway is running: `go run ./cmd/gateway/main.go` -- Check listen address: `curl http://localhost:8080/healthz` - -**Q: Getting "unknown workflow" error?** -- Check spelling of workflow name (case-sensitive) -- Available workflows: `chat-and-embed`, `multi-model-chat`, `rag-pipeline`, `batch-embeddings` - -**Q: Getting model-related errors?** -- Ensure the model is configured in your gateway setup -- Check available models: `curl https://api.riotpiao.com/v1/models` - -**Q: Workflow timing out?** -- Increase timeout: `"timeout": 120` -- Check upstream services are responsive - ---- - -## 📖 Full Examples - -### Example 1: Question Answering with RAG - -```bash -curl -X POST https://api.riotpiao.com/workflows \ - -H 'Content-Type: application/json' \ - -d '{ - "workflow": "rag-pipeline", - "timeout": 30, - "input": { - "query": "What is machine learning?", - "documents": [ - "Machine learning is a type of AI...", - "Deep learning uses neural networks...", - "Python is great for ML...", - "Statistics is important..." - ], - "top_k": 2 - } - }' | jq '.output.chat_response.choices[0].message.content' -``` - -### Example 2: Model Comparison - -```bash -curl -X POST https://api.riotpiao.com/workflows \ - -H 'Content-Type: application/json' \ - -d '{ - "workflow": "multi-model-chat", - "input": { - "models": ["reasoning", "ornith:35b"], - "messages": [ - {"role": "user", "content": "Explain blockchain"} - ] - } - }' | jq '.output[] | {model: .model, answer: .result.choices[0].message.content}' -``` - -### Example 3: Batch Vector Processing - -```bash -python3 << 'EOF' -import requests - -response = requests.post( - "https://api.riotpiao.com/workflows", - json={ - "workflow": "batch-embeddings", - "input": { - "texts": [ - "Alice in Wonderland", - "Python Programming", - "Machine Learning Basics", - "Web Development" -
