Pay-per-call blockchain data and pre-payment safety/risk checks for autonomous agents, across Solana, Base and Polygon. One MCP server, neutral tools with an explicit `chain`. Settles over x402 (USDC on any of the three chains) with no accounts or API keys.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"47620-multichain-data-api","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.
