# Registrar una dirección cripto

POST https://app.recurrente.com/api/crypto_addresses
Content-Type: application/json

Registra una dirección de destino para envíos de stablecoin. Requiere completar la verificación de stablecoin en la app.

Reference: https://docs.recurrente.com/referencia-api/api-reference/crypto-addresses/create-crypto-address

## Authentication

- `X-SECRET-KEY` header (required) — Tu clave secreta de API. Una llave de cuenta (`sk_live_...`, `sk_test_...`) opera sobre su propia cuenta y, con `X-ACCOUNT-ID`, sobre sus cuentas conectadas. La llave también fija el ambiente: una `sk_test_` solo lista y resuelve objetos de prueba (`live_mode: false`) y una `sk_live_` solo objetos reales. Un ID del otro ambiente responde `404` (`401` en `/customers`). Una llave de organización (`sk_org_live_...`, `sk_org_test_...`) alcanza todas las cuentas de una organización y solo sirve para leer: saldos, movimientos y reportes. Para operar sobre una cuenta debe nombrarla con `X-ACCOUNT-ID`; omitirlo en una lectura devuelve todas las cuentas de la organización. Cualquier otro endpoint responde `403` con `code: organization_key_unsupported`.
