note: >-
  The OpenAPI declares no securitySchemes; the auth model is documented in the machine-readable
  /api/ index and llms-full.txt. The core surface (evaluation, lookup, search, geolocation) is
  anonymous. Paid operations use the x402 HTTP 402 payment protocol (USDC on Base) via the
  X-PAYMENT header rather than accounts or API keys.
schemes:
  - name: none
    type: none
    description: >-
      Public, no credential. Applies to evaluation (POST /api/avaliar), CNPJ lookup, search,
      export, autocomplete, reference vocabularies, geolocation, discovery documents and the MCP
      endpoint. Some origin routes may be geo-restricted to Brazil.
  - name: session
    type: apiKey
    in: header
    header: x-radar-session
    description: >-
      Anonymous monitoring session: POST /api/monitor/session returns a uuid sent as the
      x-radar-session header on all monitor routes. There is no login — whoever holds the uuid
      owns the session, so it must be treated as a secret.
  - name: credito
    type: http
    scheme: bearer
    header: 'Authorization: Bearer cred_… (or X-Credito)'
    description: >-
      Prepaid credit token: POST /api/credito is paid once via x402 and returns a bearer token
      (cred_ prefix) that debits any paid API in the house. Shown once, not recoverable; not an
      account — a bearer of balance.
  - name: token
    type: http
    scheme: bearer
    description: >-
      Operator metrics token (METRICS_TOKEN) as Authorization Bearer on GET /api/metrics for the
      full 7-day series; without it the endpoint returns a public subset.
  - name: x402
    type: payment
    header: X-PAYMENT
    description: >-
      x402 micropayment protocol: exhausted quota or a paid operation returns HTTP 402 with
      accepts[] (USDC on Base); the client pays and repeats the same call with the X-PAYMENT
      header. Prices: $0.50/watch/30 days beyond the free 10, $0.10 per agent contact.
