Add x402watch to ecosystem

[bakyang2]

Summary

Adds x402watch to the ecosystem partners directory.

x402watch is a wash-filtered intelligence layer for the x402 ecosystem — read-only dashboard, daily CC0 datasets, x402-native paid endpoints, and a remote MCP server.

Differentiation

• Wash filter: 8-label buyer detection (organic_user, suspected_wash, self_test, developer, ai_agent, analytics_bot, exchange_user, verifier) with daily live recomputation
• Open data: All datasets daily commit to CC0-licensed GitHub repo (printmoneylab/x402watch-data)
• AI native: Remote MCP server (streamable-http) at https://api.x402.printmoneylab.com/mcp + 5 paid endpoints settling in USDC
• Coverage: 36k+ services indexed across Base, Solana, Polygon, and Arbitrum, AI-classified into 33 categories

Settlement Wallet

0xcF9223eCe895258dEa8D288AEBcf846Ab8E342fB — already running successful settlements on Base mainnet via the CDP facilitator. The same wallet has 4 endpoints from a sister project (kr-crypto-intelligence) already indexed in CDP Bazaar discovery.

8-label buyer detection + a wash filter is something the ecosystem has been missing — read-only intelligence on x402 traffic patterns is genuinely useful. Filed #140 for x402-saas (hosted onboarding proxy + multi-tenant data plane). Different layer entirely (we sit on the request path; you analyze the resulting flows), but happy to contribute back tagged anonymized event-ledger data once we have real tenant volume — let me know if there's a shape that'd be useful for the dataset.

Thanks for the kind words and for sharing your project.

Re: data collaboration — happy to revisit once x402-saas has live tenant
volume and a verifiable production deployment. For now we'll continue
building the wash detection methodology in the open on our own data.

The full methodology will be public at https://x402.printmoneylab.com/docs/methodology
once finalized — feel free to use anything from there.

Best of luck with x402-saas.
