The DTCC Fixed Income MBSD Electronic Pool Notification (EPN) API enables clients to exchange messages to buy and sell securities. DTCC works as the centralized authority for receiving, validating, acknowledging, and forwarding messages to the clients. This API is not yet available, but will be soon.
This API is provided by the Depository Trust & Clearing Corporation (DTCC), an American post-trade financial services company that provides clearing and settlement services. In order to access APIs, developers will need to contact their DTCC Relationship Manager or email RMSupport@dtcc.com with subject line "DTCC API Marketplace Inquiry".
