info:
  title: Locus Pro API
  description: >-
    Production is live at https://api.paywithlocus.com/api. Stage remains
    available for evaluation and integration testing at
    https://api.stage.paywithlocus.com/api; credentials, balances, and tenant
    data are isolated by environment. Embedded prepaid credits over the Locus
    pay-per-use catalog. Money and top-up amounts use exact decimal strings (up
    to 6dp). Every burn requires an Idempotency-Key header. Management routes
    accept a tenant secret key or authorized dashboard session as shown per
    operation. Widget routes accept an end-user JWT alone; when a publishable
    key is present it must belong to the JWT's tenant. MCP uses OAuth 2.1
    Authorization Code with PKCE by default and also accepts the explicitly
    documented tenant secret key, end-user JWT, or scoped agent connection
    compatibility credentials. Burns accept the execution credentials shown per
    operation. Publishable keys never authorize management or burns by
    themselves.
