API Gateway

One front door to many services: routing, auth, limits and observability.

17 capabilities 1 sections reference specification

Build against it

# give your agent the catalog — no account, no install
claude mcp add provespec -- npx -y provespec-mcp

# then, from any agent session
spec_get(slug: "api-gateway")                → the capability tree
spec_checklist(slug: "api-gateway")          → the questions to answer
spec_grade(slug: "api-gateway", grades: [...])  → parity % + the gap list

# or just fetch it
curl https://provespec.com/catalog/api-gateway/spec.json

Grade every capability below as yes · partial · no · na, with a file reference as evidence. Whatever you leave ungraded counts as missing — the gap list is the work queue.

Or just paste this to your agent

Use the ProveSpec MCP server. Fetch the "api-gateway" spec with
spec_get, then walk spec_checklist and grade this repository against it —
one verdict per capability, each with a file reference as the note.
Call spec_grade with the results and give me the gap list as the plan.

If the server is not registered, add it first:
  claude mcp add provespec -- npx -y provespec-mcp

The specification

Routing

✓ Route by host, path, method and header
✓ Path rewriting and prefix stripping
✓ Versioning strategy for the public surface

Auth

✓ Validate tokens at the edge before the backend sees them
✓ API keys with per-key quota
✓ Pass verified identity downstream, signed

Limits

✓ Rate limiting per key, per IP and per route
✓ Request and response size caps
✓ Quotas with a documented reset window

Resilience

✓ Timeouts, retries and circuit breaking per upstream
✓ Graceful degradation with a cached or static response

Transform

✓ Request and response transformation
✓ Protocol translation where offered REST ↔ gRPC

Observability

✓ Correlation id propagated end to end
✓ Per-route latency, error rate and traffic

Governance

✓ Declarative configuration under version control
✓ Staged rollout of configuration changes
