  StepFun open-platform quickstart and API reference. No OpenAPI is published
  (the docs' openapi.json is the Mintlify placeholder), so this profile is
  captured from the documentation rather than derived from a spec.
summary:
  types: [http-bearer-api-key]
  api_key_in: [header]
  oauth2_flows: []

  - name: bearerAuth
    type: http
    scheme: bearer
    description: >-
      Platform API key sent as "Authorization: Bearer <STEP_API_KEY>" on every
      request (REST and WebSocket). Keys are issued in the platform console
      under 接口密钥 (interface keys). The same key authorizes the StepSearch
      hosted MCP server. OpenAI/Anthropic SDKs pass it as their api_key with
      base_url pointed at https://api.stepfun.com.
    key_console: https://platform.stepfun.com/interface-key
notes:
  - No OAuth 2.0, OIDC, or scoped-permission surface is documented; access is all-or-nothing per API key.
  - Step Plan subscription traffic authenticates the same way against the /step_plan/v1 prefix.
