Using the RTP Directory

COS offers an RTP directory that partners can use to determine which RTP-related services are supported by a particular financial institution. This can be done by calling GET /rtp/v1/directory and accommodates filtering by details such as routing number or financial institution name. Here's an example of a request URL filtering by a specific routing number, 021000021:
