Procurement

Screen a federal contractor by UEI or CAGE

Screen one US federal entity against the currently loaded SAM.gov registration and exclusion data, USASpending award data, and available FAPIIS and FAR 4.18 fields. Returned blocks identify available source and date metadata and include a 'confirm at SAM.gov' pointer; provenance fields can be null.

Provide exactly one of uei or cage. Pass as_of=YYYY-MM-DD to query retained SAM or procurement history where rows have been banked; this is not universal replay for every entity or date. A zero-exclusion or unknown-identifier result is returned only when SAM serving coverage reconciles to a comparable attested artifact; otherwise HTTP 503 carries exclusion_determination: indeterminate and the coverage evidence.

Defamation-safe: no risk score, no 'fraudulent' / 'likely excluded' label, no derived verdict; confirmed UEI/CAGE matches only; opt-out entities withheld; public-tier federal data only (no FOUO). Screening aid, not a certification.

Requires Authorization: Bearer fnt_... and uses the key's configured limits.

Query parameters

ueistring

12-char GSA Unique Entity ID (the procurement spine). Provide this OR cage.

cagestring

5-char CAGE/NCAGE code; resolved to the entity's UEI. Provide this OR uei.

as_ofstring date

ISO date (YYYY-MM-DD). The retained coordinate currently applies only to banked USASpending award rows; SAM.gov registration, exclusions, FAPIIS, and ownership fields may be current, absent, or null. Omit for the current request.

Response

Screening result with dated facts and available per-source provenance. A zero-active-exclusion, unknown-identifier, or opted-out result is HTTP 200 only when the endpoint's SAM coverage guard reports internally reconciled current; otherwise the fail-closed response is HTTP 503.
