The API wrapping the DMF data currently has one endpoint, /dmf, which accepts GET requests with a social security number as input, like so:
/dmf/<ssn>
<ssn> can be in the form 123-45-6789 or 123456789.

The API returns a JSON object with three keys:
ssn: The SSN sent in the request
name: The full name associated with the SSN, if available
dmf_record_present: Whether there is a record in the DMF associated with this SSN
