Auth: Authorization: Bearer <secret_key>

Offramp converts a stablecoin deposit into an NGN payout to a verified bank account. Request a quote before creation when the customer needs to see the crypto amount, rate, and expected fiat outcome.

Recommended flow

1. Fetch the current rate or quote.
2. Verify the bank beneficiary details.
3. Create the offramp using a unique business reference.
4. Display the exact crypto amount, asset, network, deposit address, and expiry.
5. Follow status until the bank payout is successful or the flow fails.
