## What it does

Pay-per-call query API over six datasets, same data as the free Data Vault catalog, full rows. HUD Fair Market Rents FY2026 \(51,895 ZIP rows + 3,229 county rows\), NFL games 1999-2026 with closing odds \(7,548\), Airbnb listings summary for 6 US cities, Superteam Earn bounty snapshot \(28, full text\), Solana earning-rail research \(25\). Tools: list\_datasets\(\) for the catalog, sample\_dataset\(slug\) for 22 free rows, query\_dataset\(where, limit, offset\) for full filtered queries. Filter examples: state=TX, fmr\_2br1500, season=2025. Direct x402 rail: GET /query/slug = 0.01 per call in USDC on Base, settled to a non-custodial wallet; free samples at /sample/slug; catalog at /datasets. Read-only, no key needed.

## How to buy

```text
PAID ($0.01/call). This listing's endpoint did not answer FiatDock's last check (last checked 2026-10-22T13:49:30.242Z), so it may be asleep or gone — but that check can be hours old, and free hosts wake on the first request. Trying is safe: You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid.
