Required

met: Locally denominated asset (stablecoin or stablebond) on Stellar CETES / TESOURO stablebonds on Stellar

Brazil support (BRL ↔ TESOURO over PIX) is underway and undocumented: Etherfuse's published FX API and OpenAPI spec currently cover only Mexico (MXN ↔ CETES over SPEI) plus USD-denominated stablecoins (USDC, EURC). The Brazil/PIX request and response shapes in this client are speculative and unverified against a live environment.
If you try to create your customers through API calls, submitting the various "agreements" via POST requests to Etherfuse currently fails with a 406 error. This blocks customer KYC via these API methods. The Onboarding URL approach still works.
