  update:
    x-sandbox-key: test-api-key
    x-sandbox-note: >-
      The literal key "test-api-key" returns a fixed dummy response on Domain Search,
      Email Finder and Email Verifier. Published by Hunter at
      https://hunter.io/api-documentation/v2#authentication
- target: $.info
  update:
    x-error-envelope: '{"errors": [{"id": "...", "code": 400, "details": "..."}]}'
    x-error-note: >-
      Not RFC 9457. Branch on errors[0].id. 403 means the per-second/per-minute rate limit was
      hit and IS retryable with backoff; 429 means the monthly credit quota is exhausted and is
      NOT retryable. 451 encodes a GDPR erasure request on the enrichment endpoints.

  update:
    x-idempotency:
      header: Idempotency-Key
      operations: [POST /v2/sequences]
      retention: 24h
      note: Sequence creation only. Lead creation and bulk operations have no replay protection.
- target: $.info
  update:
    x-pagination:
      style: limit-offset
      params: [limit, offset]
      response: [meta.total, meta.limit, meta.offset]
      max_offset: 10000
      note: Discover People uses a search_after cursor instead of an offset.
- target: $.info
  update:
    x-rate-limit-headers: none
    x-rate-limit-note: >-
      Hunter publishes no X-RateLimit-* or RateLimit-* response headers, so a client has no
      runtime budget signal and must pace itself against the documented per-endpoint numbers.
