Cryptocurrency Transfers

Get Cryptocurrency Transfer

Get a cryptocurrency transfer using its ID.

Eventual Consistency

Cryptocurrency transfers involve multiple processing stages - asset pricing checks, compliance verification, and blockchain confirmation - which can take significant time to complete. For this reason, the submit endpoint is designed to be asynchronous, returning immediately after accepting your request. Due to this design, there is a brief window (typically milliseconds) where a newly submitted transfer may not yet be queryable. If you call this endpoint immediately after submission and receive a 404 Not Found response, simply retry after a short delay. Once available, you can use this endpoint to track the transfer through all its processing stages until completion.
