Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

sample

get_sample_score

Returns a clearly-marked stale sample counterparty score in the exact response schema of score_x402_counterparty (verdict, wash_trading_ratio, real_buyer_count, repeat_buyer_rate, source, updated_at, confidence). Free, no payment required, no input required. Sample data is fixed and expired by design — use it to validate response parsing, then call score_x402_counterparty ($0.02/call) for fresh decision-grade scores.

score

score_x402_counterparty

Returns trust verdict (trusted/caution/avoid) with wash-trading ratio, real-buyer count, and repeat-buyer rate for an x402 endpoint URL or pay-to address. $0.02/call. Computed from Base on-chain settlement data and the x402 Bazaar catalog; a score is sold only if refreshed within the past 24 hours.

x402 Counterparty Score — questions

Answers built from our own checks of this server.

What can x402 Counterparty Score do?

It exposes 2 tools, read directly from the server on our last check. Among them: get_sample_score, score_x402_counterparty. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is x402 Counterparty Score working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 77 of 91 checks got a reply (84.6%), average response time 1490 ms. The bar chart above shows every period we have measured.

How do I connect x402 Counterparty Score?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does x402 Counterparty Score need an API key?

No. x402 Counterparty Score completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is x402 Counterparty Score?

It answers our handshake in 1490 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
