🚧 Beta — This endpoint is in beta. Its results may not be accurate, so don't rely on it as a fully-supported endpoint yet.

List the available enrollment methods given a card BIN.

The Unified Enrollment SDK v2 calls this endpoint each time a person presses Continue on the card number screen, with the first 8 to 11 digits they typed (8 by default), and routes the session from the answer together with GET /bin-lookup. The SDK token therefore needs enrollment-methods:write. If your own backend calls it, send up to 11 digits for the most precise answer.

When Mastercard's live BIN data is unavailable, the response is built from static BIN data and Astrada's allowlists instead of failing, and binInfo comes from the static data. bulkLikelihood is then capped at medium, except for BINs with proven bulk history, which stay proven. When nothing decides the grade, bulkLikelihood is omitted and unavailable lists it; singleEligible is then always true, so availableEnrollmentMethods is ["cardholder-single"]. Retry later for a full answer.
