  title: API Evangelist overlay for the temp.md Public API
  version: 1.0.0
extends: openapi/temp-md-openapi.yml
x-generated: '2026-09-19'
x-method: generated
x-source: openapi/_original/temp-md-openapi.json + https://temp.md/docs + live response headers from api.temp.md (2026-09-19)
x-rationale: >-
  The published spec is clean (23 operations, all with operationIds and summaries, typed error responses) but
  omits a few things the provider documents elsewhere or that were observed on the wire. This overlay adds them
  WITHOUT mutating the original: externalDocs, tag descriptions and a tag for the untagged health check, the
  X-Request-Id response header the API sends on every response, the Retry-After header's semantics, and
  operation-level notes carried from docs/llms.txt (idempotency, atomic update, lifecycle windows). Apply with
  any Overlay 1.0.0 processor against openapi/temp-md-openapi.yml.

- target: $.components.headers
  description: Declare the correlation header observed on every response so clients can log it.
  update:
    X-Request-Id:
      description: Correlation id (UUID) for support and log lookup; also returned as request_id in error bodies.

- target: $.components.responses.RateLimited.headers.Retry-After
  update:
    description: Seconds to wait before retrying. The JSON body repeats it as retry_after.
- target: $.paths['/temps'].post
  update:
    x-idempotency: none - a retried POST creates a second Temp; use POST /publish-sessions with Idempotency-Key for a replay-safe publish.
    x-rate-limit: 60 per hour per IP (anonymous)
- target: $.paths['/publish-sessions'].post
  update:
    x-idempotency: Idempotency-Key header required (<=128 chars); same key + same manifest returns the existing session (200), different manifest -> 409.
- target: $.paths['/temps/{tempId}'].put
  update:
    x-atomic-update: A failed update never replaces the live Version; the previous Version keeps serving.

- target: $.paths['/temps/{tempId}/restore'].post
  update:
    x-reversal-window: Within 7 days of expiry (limits.json restoreGraceSeconds 604800); 410 once the window closes.

  update:
    x-irreversible: true
    x-note: Deletes every stored Version and invalidates all capabilities; cannot be restored.
