note: >-
  API Evangelist operates this catalog and is also a provider listed in it. This
  artifact is first-party: every limit below is transcribed from API Evangelist's
  own published plans and authentication pages rather than researched about a
  third party, and is disclosed rather than assumed.
description: >-
  The API Evangelist Network API and Governance & Discovery API are read-only and
  meter per API key, with the free tier metered without a key. Free is throttled
  both per second and per day; the paid tiers are published as daily request
  ceilings. Enterprise limits are negotiated. Rate limits are documented on the
  plans page rather than returned as response headers today — a consumer should
  treat the published daily ceiling as the contract and request higher limits by
  email rather than relying on a header to discover the remaining budget.

    metric: requests_per_day

    scope: key
    metric: requests_per_day
    limit: -1
    timeFrame: day
    notes: Custom and negotiated. Contact info@apievangelist.com.
  - name: Pagination ceiling
    scope: request
    metric: records_per_request
    limit: 100
    timeFrame: request
    notes: >-
      The page + limit pair caps at limit=100 on every collection endpoint. A
      structural ceiling rather than a plan-tier throttle, recorded because it
      bounds how fast a consumer can drain a collection within its daily quota.
raising_limits: >-
  Keys are issued per consumer with limits matched to the use case. Pro and Team
  are self-serve through Stripe checkout at https://developer.apievangelist.com/account;
  higher or custom limits are arranged by emailing info@apievangelist.com.
gaps:
  - >-
    No RateLimit response headers are served today, so a consumer cannot read the
    remaining budget from a response. Recorded as a known gap rather than omitted.
  - >-
    No documented 429 throttling response or Retry-After contract. Consumers
    should back off on any non-2xx and consult the published daily ceiling.
