CEP / SPEI Payment Validation
Credits: 1 per call.
Validates a Mexican SPEI transfer against Banco de México’s official CEP service (“Comprobante Electrónico de Pago”) and returns the verified transfer details together with Banxico’s cryptographic proof. Use it to confirm that a SPEI payment actually settled, for reconciliation, payout confirmation, or fraud checks on a claimed transfer.
