get_service — Everything known about one x402 seller by host: every grade earned by actually paying it, what was quoted versus what was charged, whether goods arrived, plus its settlement volume and Organic Demand Score.
search_services — Search the graded ledger by hostname, behaviour graded, or words in the finding's title.
top_services — Rank sellers by money received or by Organic Demand Score.
list_traps — The field notes: each is a specific way an agent paying an API loses money or is misled, what it cost to learn, and what to do instead.
most_accurate — For a category with an objective ground truth (crypto-price, stock-price, fx-rate, gas-price, wallet-balance, weather), the sellers we PAID ranked by how close their returned value was to a primary source that cannot be a reseller (exchange median, chain balanceOf, ECB rates, FMP quote).
preflight — The single call to make before your agent pays an unfamiliar x402 API, the check it runs before the 402.
market_summary — What actually settled on Base in the last day: total USDC, number of payments, services tracked, and the date of the tape.
