  note: >-
    NO rate-limit response headers. A live unauthenticated request returned only
    date, content-type, server, cache-control, x-robots-tag and the CORS headers --
    no X-RateLimit-*, no RateLimit-*, no Retry-After. Quota is discoverable only
    out of band, by calling GET /api/v2/status, which returns
    {"remaining_requests": <n>}. An agent cannot back off from a response; it must
    poll /status.
  quota_endpoint: GET /api/v2/status
statusOnExhaustion: 403
statusOnExhaustionNote: >-
  Quota exhaustion returns 403, the same status as a wrong key and the same status
  as calling an endpoint the plan does not entitle. The published error table says
  so explicitly: "403 Forbidden -- API key is wrong, you don't have enough requests
  or you don't have enough rights to access it." There is no 429 anywhere in the
  documented catalog.
name: Zenserp Rate Limits
description: >-
  Zenserp enforces monthly search quota limits based on the subscribed plan.
  Concurrent connection limits apply across all plans, with the ability to
  increase concurrency upon request. The service targets 99.9% uptime and
  only counts successful responses against a user's quota. Failed or invalid
  API requests do not consume quota.
