Connect X402 List and your agent gets 7 tools, among them x402_assess_services, x402_change_events, x402_check_health. It answers at https://mcp.x402-list.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Find and vet x402 payment APIs before your agent pays one: uptime, price, on-chain volume.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
x402_assess_services | Call this when the free signals have run out: you hold 2 to 8 finalists from x402_search_services or x402_find_best_service, their stored fields do not separate them for YOUR stated need, and choosing wrong costs more than a quarter. It buy Inputs: question, services, payment_signature_b64, probe |
x402_change_events | Call this before you trust anything you cached about a service, and right after a payment failed for no obvious reason: the monitor's log of what moved under you. Returns payTo, price and 402-schema changes observed on listed services, most Inputs: service, type, days, page, per_page |
x402_check_health | Call this before you send a payment, or right after a call unexpectedly failed: is this service up right now. With no slug, the directory snapshot: five status counts across 500+ services (include_services=true attaches every row). With a s Inputs: slug, uptime_period, include_services |
x402_facilitator_volumes | Call this when the question is about the rail rather than the service: which x402 facilitator actually settles money, and how much. Returns on-chain-verified settlement volume and transaction counts per facilitator for today (UTC), 7d, 30d Inputs: timeframe, include_timeseries, include_chains, days, page, per_page |
x402_find_best_service | Call this when you have a need in words and want one service to call rather than a list to read: it is the free ranking step between searching and paying. Pass the need as q, plus any category, network, price cap or verification requirement Inputs: category, network, q, max_price_usd, require_verified, prefer |
x402_get_service | Call this once you hold a slug and are deciding whether to commit to that service: the full record behind a directory row. Live status, uptime over 24h/7d/30d/90d, average response time, networks and settlement asset, every priced endpoint, Inputs: slug, include_series |
x402_search_services | Your first call when you do not know which x402 service exists for a job: it narrows a directory of 500+ listed services to candidates. Filter by free-text query, category, network, live status, and whether the last observed 402 envelope is Inputs: q, category, network, status, verified_only, signable |

It answered our last check on 19 October 2026 in 191 ms. Over 6 checks since 10 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by x402-list.com and served from mcp.x402-list.com, the vendor's own domain: https://mcp.x402-list.com/mcp.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.x402-list.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
