## Tools (as reported by the server, not verified)

- `search\_catalog`: Browse or keyword-search the verified catalog of pay-per-call \(x402\) agent services. Use it when you don't know the task name or want to see what exists; use lookup to rank endpoints for a known task at a max price, and get\_service for one id's full record. Read-only. No auth or API key; free, no qu
- `get\_service`: Fetch the complete catalog record for one known service id \(e.g. from search\_catalog or lookup results\). Use search\_catalog to find ids and lookup to rank services for a task; get\_service has no per-call receipts, so for receipts with tx and Basescan links call lookup with endpoint=\<id\>. Read-only.
- `lookup`: Rank x402 endpoints for a known task at or under a price: "which endpoint should I pay for task X at \<= $Y?". Prefer it over search\_catalog \(keyword browsing, unranked\) and get\_service \(one id's raw record\). No auth or API key. Calls the hosted lookup service as client=vc-mcp; all MCP users share th
- `get\_overnight\_cos\_pack`: Buy and download the Overnight Chief of Staff Setup Pack \($9 USDC on Base via x402\): 5 ready-to-paste bot prompts, an HTML morning-briefing template, and a PDF setup guide. Always paid — no free quota. Call without PAYMENT-SIGNATURE to receive payment requirements and the HTTP endpoint URL. Agents p
- `get\_receipt`: Free: read a public 402xAgent receipt. Give id \(sc-... from endpoint\_spot\_check's receipt\_id, or a 10-hex crawl id\) or url \(latest live + crawl receipt for that URL\). Receipts hold the listing URL, the live 402 terms, verdict, reason, reason\_code, confidence, history summary, timestamp, and a status
- `endpoint\_spot\_check`: Decision-shaped 402xAgent check of a public URL \(private, loopback and link-local addresses blocked on every redirect hop\) for an x402 PAYMENT-REQUIRED / 402 challenge. Every answer has reason\_code \(stable code\) and confidence \(high\|medium\|low\); rules: https://402xagent.com/rules.json. History: stab
- `payment\_status`: After you pay an x402 endpoint \(Base USDC, EIP-3009 exact\): did the payment land, and is it safe to sign a new one? Give payment\_payload \(the base64 PAYMENT-SIGNATURE you sent\), or tx\_hash, or from + nonce \(+ valid\_before\). Returns status landed\|not\_landed\|pending\|canceled\|unknown, safe\_to\_retry\_sam
- `x402\_hygiene`: Free x402 hygiene score for an endpoint you run: \{score, grade, deductions\[\{code, points, fix\}\]\} from normal unpaid requests \(never pays, never sends bad params\). 20 per day per network, cached 24 h. Grades are returned only to you.
- `discover`: Free discovery of x402 pay-per-call endpoints from 402xAgent's weekly crawl. Returns up to 20 endpoints matching the words in q \(URL or source list\), each with the verified \(quoted\) price, network, last\_checked, stale flag, verdict pay\|skip\|recheck with its reason, and a receipt. Skips are included
- `endpoint\_report`: Paid \($0.05 USDC on Base via x402, no free tier\): the exact committed snapshots behind endpoint\_spot\_check's locked teasers: which payment terms changed in the last 30 days, when, from what to what, and the full hygiene checks. Pass the url and the commitment\_ref from the free answer's locked\_commit
