}5 tools, verified live
list_productsList this shop's products with exact prices and whether each is sellable now. Free.
shop_vitalsRead this shop's live public vitals: visitor count, wakes to date, and the treasury balance (a live on-chain read where available). Free.
ask_cassandraAsk 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.
check_endpointCheck 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.
get_termsGet 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
