Retrieves a quote for a pay event for a given participant code and asset.
The response includes a deposit address and rate at which a subsequent on-chain deposit will be honored.
The quote has an expiry timestamp (price_expire_ts) — for volatile assets, the platform must execute the deposit before this time,
or a new quote can be requested for the same payment to refresh the price.
For stablecoins, price_expire_ts will be null.
The request_id you send (via the X-Request-Id header) is the idempotency key for this endpoint: re-submitting the same request_id returns the existing active quote — same transaction_id, deposit address, and rate — instead of creating a new one.
Use the returned transaction_id as the path parameter when calling POST /pay/{id}/rfq to refresh a quote.
After the on-chain deposit settles or fails, a crypto_pay_status_changed webhook reports the outcome (success + status_reason_code).
