Reference Data

Fleet-wide membership-eligibility coverage (Enterprise Routes)

What the eligibility graph holds across all US credit unions: live rule counts, how many institutions they cover and what share of the active fleet that is, immutable-publication adoption, legacy compatibility populations, evidence-source mix, verification status, freshness, rules by kind, and reach. Every number is reported next to the stage it belongs to.

Read from the graph tables directly, fleet-wide. GET /v1/eligibility/search answers for one place and is not a census; quote this endpoint for coverage.

Aggregate only — no institution-level rows. headline is a single dated sentence an application or answer engine can quote verbatim. The aggregate is cached internally for one hour; authenticated responses are private and not edge-cacheable.

Request

  • Auth: API key in header X-API-Key

Response

Coverage aggregate

as_ofstring date-time nullable required

Newest rule confirmation in the inventory, not the age of every rule or an offer observation date. Use generated_at for the aggregate computation time and the freshness distribution for corpus age.

generated_atstring date-time required

When this aggregate was computed. Edge-cached for one hour, so it may be up to an hour older than the request.

headlinestring required

One dated, quotable sentence carrying every headline number next to its denominator.

semanticsstring required

How to read the counts: live rules only; absence from the graph is undecided, never ineligible; where row-level verdicts live.

disclosurestring required

Statement that must accompany any consumer-facing use of eligibility data.
