SAM.gov maintains the federal exclusions list: contractors and entities that are debarred, suspended, proposed for debarment, or otherwise excluded from receiving federal contracts, grants, or other assistance.
| List | What it covers | Source |
|---|---|---|
| SAM.gov exclusions | Debarred / suspended / excluded contractors | GSA / SAM.gov |
| OFAC sanctions | Cross-checked for sanctioned parties | U.S. Treasury |
| OIG-LEIE | Cross-checked for healthcare exclusions | HHS-OIG |
Submit the contractor's legal name (and optionally its UEI). The API checks SAM.gov plus the sanctions and healthcare exclusion lists, deduplicates an entity that appears on several, and returns the exclusion classification and source link.
