# Latest on-ramp attempt + banking instructions for this invoice (buyer's own).



## OpenAPI

````yaml https://api.caratuva.com/docs-json get /v1/public/invoices/{publicId}/on-ramp
openapi: 3.0.0
info:
  title: Caratuva API
  description: >-
    Cross-border B2B payments. Fiat on-ramp → USDC → PIX off-ramp.


    Every request runs in **test** or **live** mode on this single host — there
    is no separate sandbox URL. API keys carry the mode in their prefix
    (`pk_test_…` / `pk_live_…`); dashboard JWTs start in test and re-mint via
    `POST /v1/auth/switch-mode`. Test mode runs the full pipeline against a
    sandbox payment instance (KYB/KYC auto-approve, no real money); live runs on
    real rails and requires approved KYB. Test and live data are fully isolated.
    Check readiness with `GET /v1/onboarding/status`.
