Agent and partner traffic

Via20 public API docs

Via20 is preparing public, signed quote-consumer access for software agents and partners. Current public endpoints expose server-side reference rates and provider-published VET discovery without exposing provider credentials client-side.

Current endpoints

• GET /api/fx/reference-rates - midpoint reference-rate cache metadata.
• GET /api/provider-vets?fromCountry=Portugal&toCountry=Brazil&amount=100&sendCurrency=EUR&receiveCurrency=BRL&payoutMethod=PIX - provider-published VET quotes where configured.

A2A readiness

Production A2A access will require service identity, signed requests, idempotency keys, expiry windows, replay protection, policy controls, rate limits, audit logging, and compliance mapping.

APPROVAL REQUIRED before opening production partner or A2A credentials.
