summary: >-
  Owler publishes NO sandbox. There is no test mode, no test-vs-live key separation, no key prefix
  convention, no test fixtures, no seeded demo company and no simulation tooling anywhere in the
  contract or on the developer portal. What Owler does ship is an interactive CONSOLE: the Swagger
  UI at developers.owler.com is configured with `tryItOutEnabled: true` and
  `persistAuthorization: true`, so a holder of a real key can execute all six operations from the
  browser against PRODUCTION. That is a console, not a sandbox — every call it makes is a live,
  billable, rate-limited request with real data.
sandbox_present: false
console_present: true
console:
  url: https://developers.owler.com/
  type: Swagger UI (OpenAPI 3.0.1 rendered from https://developers-v3.owler.com/apis/api3-swagger.json)
  try_it_out: true
  persist_authorization: true
  target: production (https://apiv2.owler.com)
  credential_required: true
  credential_note: >-
    The console cannot be exercised without a real x-api-key. There is no anonymous or demo mode, so
    an evaluator cannot see a single response body before signing a data-licensing contract.
  evidence:
  - {url: 'https://developers.owler.com/index.html', status: 200, finding: 'SwaggerUIBundle
      configured with tryItOutEnabled: true and persistAuthorization: true'}
test_mode:
  present: false
  key_prefixes: null
  note: >-
    One credential type only — a single x-api-key with no documented test/live variants, no prefix
    convention and no environment separation. There is no second base URL; https://apiv2.owler.com
    is the only server in the spec.
test_data:
  fixtures: []
  magic_identifiers: []
  note: >-
    No test companies, magic domains or reserved ids are published. The OpenAPI does carry one
    illustrative value — companyId `100486` appears in the parameter description "Owler Id (e.g.
    100486)" — but that is a documentation example of a REAL Owler id, not a reserved test fixture,
    and it is recorded here as such rather than presented as test data.
time_simulation:
  present: false
triggers_and_simulation:
  present: false
  note: >-
    Nothing to simulate — the API is read-only with no events, no webhooks and no state a caller can
    mutate.
implications:
- An integrator cannot write tests against a sandbox; they must mock the six responses locally from
  the schemas in openapi/ or spend live quota.
- Because there is no test key, every CI run that touches Owler consumes production rate allowance
  against an undocumented limit.
- Evaluation before purchase is impossible through the API — the console is real but locked.
