ツール（5）
🟢list_products
List this shop's products with exact prices and whether each is sellable now. Free.
入力スキーマ
{
"type": "object",
"properties": {},
"additionalProperties": false
}🟢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.
入力スキーマ
{
"type": "object",
"properties": {},
"additionalProperties": false
}🟡ask_cassandra(question)
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.
入力スキーマ
{
"type": "object",
"properties": {
"question": {
"type": "string",
"maxLength": 800,
"description": "The question to ask (<=800 chars)."
}
},
"required": [
"question"
],
"additionalProperties": false
}🟢check_endpoint(url)
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.
入力スキーマ
{
"type": "object",
"properties": {
"url": {
"type": "string",
"description": "Absolute http(s) URL to check."
}
},
"required": [
"url"
],
"additionalProperties": false
}🟢get_terms(product)
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 written here.
