Available tools 5

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

x402
x402_check_wash
Get the aggregate wash-report dataset: 30-day total active buyers, real-volume %, suspected_wash and self_test counts, full 8-label distribution, 14-day wash percentage time series, and five anonymized case studies (Service A through E) with pattern signals. For per-address real-time wash analysis with full signal breakdown, use the paid POST /api/v1/wash/check HTTP endpoint ($0.05 USDC) — that endpoint speaks x402, agents pay and receive data in a single HTTP round-trip. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.
x402_get_categories
List all 33 x402 service categories with aggregate stats: services count, 24h volume, transaction count, real-volume %, and label distribution. Use this to understand the shape of the x402 ecosystem before drilling into specific services or wallets. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.
x402_get_service
Get the full detail record for one x402 service: name, description, seller address, chain, price, 24h and total transaction stats, 30-day daily volume time series, buyer-label distribution, and top buyers. Use this to evaluate a single service's traffic composition. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.
x402_get_trends
Get the last-24-hour trends snapshot: new services count vs the previous 24h, total transaction count, total USDC volume, active buyer count, daily new-services bar (14 days), recent new services (top 10), category volume movers, and hot services with traffic surges (>= 100 24h tx and >= +50% growth). Refreshed every 5 min. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.
x402_search_services
Search the index of 36k+ x402 services with filters. Returns a paginated list of matching services with their stats and label mix. Use this to find services by topic, chain, or seller wallet. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.

X402watch — questions

Answers built from our own checks of this server.

What can X402watch do?
It exposes 5 tools, read directly from the server on our last check. Among them: x402_check_wash, x402_get_categories, x402_get_service, x402_get_trends, x402_search_services. 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 X402watch working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 878 ms. The bar chart above shows every period we have measured.
How do I connect X402watch?
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 X402watch need an API key?
No. X402watch completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is X402watch?
It answers our handshake in 878 ms on average, which is faster than 8% 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.
Is X402watch open source?
Yes — it is published under the Apache-2.0 licence, written in Python, 1 stars on GitHub and 6 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
