Choose this endpoint when you need authoritative, official US federal government surplus auction data sourced directly from GSA Auctions.

## Known failure modes

- GSA Auctions API downtime or rate limiting may cause failed responses
- Overly broad or ambiguous search terms may return irrelevant listings
