summary: >-
  APIFreaks has no sandbox in the payments sense — there is no test mode, no test-vs-live key prefix, and no
  magic test identifiers. What it does publish is a per-endpoint interactive Playground and a per-category
  Swagger UI console, both backed by the LIVE API. The trial mechanism is the free credit grant rather than
  a simulated environment: every call from the playground is a real call against production and spends real
  credits.
test_live_separation:
  exists: false
  key_prefixes: null
  modes: null
  note: >-
    One API key, one credit pool, one environment. Nothing in the docs, the 102 OpenAPI specs or the MCP
    server distinguishes a test key from a live key.
console:
  playground_hub: https://apifreaks.com/api/playground
  status: 200
  coverage: one playground page per API product, grouped by category
  description: >-
    Each endpoint has its own "Playground to test <API>" page with the request form for that operation.
  backing_environment: production
swagger_ui:
  hub: https://apifreaks.com/api/swagger
  status: 200
  form: per-category Swagger UI pages rendered client-side
  note: >-
    The hub is a Next.js page listing every API; it does not expose a downloadable spec URL. The actual
    machine-readable specs are published separately at github.com/api-freaks/af-openapi-specs and mirrored
    verbatim into openapi/ in this repo.
free_tier:
  credits: 10000
  card_required: false
  signup: https://apifreaks.com/signup
  billing_rule: credits charged only on 2xx; 4xx/5xx refunded
  note: This is the de-facto trial path — real endpoints, real data, granted credits.
test_values:
  published: false
  note: >-
    No test card numbers, test IBANs, magic phone numbers or reserved test IPs are published. Reserved and
    bogon IPs are rejected with HTTP 423 rather than returning canned fixtures.
free_tools:
  note: >-
    APIFreaks also publishes browser-based free tools that require no API key, useful for eyeballing the
    shape of a result before integrating.

gaps:
  - >-
    No test mode means an agent or CI pipeline cannot exercise the write-bearing PDF operations without
    consuming credits and creating real server-side resources (which are retained 7 days).
