1. Get your API key

Sign in to the partner portal and copy your consumer key from API keys. You will send it as the x-api-key header on every partner request.

2. Fetch an exchange rate

Example response:
  • Buying rate — used when you buy fiat with crypto (offramp pricing context).
  • Selling rate — used when you sell fiat for crypto (onramp pricing context).
For ramp availability flags, use POST /v2/exchange-rate.

3. Typical offramp flow

  1. Validate the destination with POST /v1/validation/{currency}.
  2. Receive a stablecoin payment on a supported chain.
  3. Call POST /v1/pay/{currency} with the transaction_hash and payout details.
  4. Poll POST /v1/status/{currency} or wait for a webhook.
See the offramp guide for currency-specific fields and limits.
