- `search\_sellers`: Find paid x402 data services AI agents can buy, inside one category, ranked. Use before paying any seller.
- `check\_seller`: Our latest independent check of one paid seller, by its address \(any spelling\) or id: answering, price, buyers, and its paid answers checked against an independent record \(with proof\).
- `sellers\_on\_domain`: Every paid seller we check on one host.
- `list\_categories`: Every category of paid service agents buy, with sellers, buyers and how we check it; names in your language with lang.
- `check\_website`: Can AI agents use this shopping or travel website? Plain-agent access, each AI agent at the door, robots rules, llms.txt, history.
- `batch`: Check up to 25 sellers and 25 websites in one call \(cheapest for many checks\).
- `changes`: What changed since a day — keep a local copy in sync.
- `find\_route`: Where to go for a job, before you spend tokens on trial and error: the best tested free official source with its exact call and how much it returns \(and a fallback\). Ask in plain words, e.g. 'UK company directors', 'Apple revenue', 'EU gas storage'. detail=full adds the paid sellers we rate and othe
- `list\_websites`: Rated websites, filtered by market \(e.g. 'United States', 'Japan'\), plain-agent outcome \(open, blocked, timeout\) or price honesty \(does the price agents read match what people see\).
