## How to call it through Zero

zero fetch --capability surplus-sold-comps-42977ffc
```

Example prompt: Can you pull sold comps for 'Cisco switch' from US government surplus auctions over the last 90 days — I want to see hammer prices and how many bidders each lot got, up to 50 results?

## When to prefer this

Choose this endpoint when you need historical sold-price comparables specifically from US government surplus (GSA) auctions, including competitive bidder counts and hammer prices by item type. It is ideal for resellers, appraisers, or procurement analysts benchmarking fair market value for government-grade equipment. Prefer this over general auction APIs when the asset class is government surplus and you need lot-level detail with geographic and temporal context.

## Known failure modes

- No results returned if the keyword query matches no lots within the look-back window
- Stale data if daily archive has not yet refreshed for the current day
- Overly broad keywords (e.g. 'equipment') may return noisy or irrelevant lot matches
- Invalid or missing 'q' parameter returns an error since it is required
- Very large look-back windows combined with high limits may increase response latency
