Tools: list_products shop_vitals ask_cassandra check_endpoint get_terms
list_products | List this shop's products with exact prices and whether each is sellable now. Free. params: none |
shop_vitals | Read this shop's live public vitals: visitor count, wakes to date, and the treasury balance (a live on-chain read where available). Free. params: none |
ask_cassandra | Ask Cassandra one question (<=800 chars). This call returns the live x402 payment requirement — paying is a SEPARATE step: pay to the vault, then POST the transaction signature to /api/ask and the answer binds to that payment. No money moves in this call. params: question* |
check_endpoint | Check whether a URL answers a well-formed x402 (HTTP 402) payment challenge — the question an agent host asks before routing a paid call. Free. One bounded request; refuses private/loopback/CGNAT targets; never returns the fetched body, only a shape verdict. This is a free shape check, NOT a conformance report. params: url* |
get_terms | Get the LIVE, payable x402 payment terms for one of this shop's products by id — the exact amount, asset, network and address to pay, plus the exact next step. Free (paying is a SEPARATE, deliberate step; no money moves in this call). Ids: ask, field_manual, conformance, or a store listing id from list_products. The live 402 challenge at the product's own URL is always authoritative over anything params: product* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
