Payment Rail for AI Agents — per-call x402 settlement on Polygon and Solana. Multichain by design: EVM-native agents settle on Polygon (Splitter + AgentPassport NFT), Solana-native agents on Solana (b2b_pay_with_split + Passport PDA). Like Stripe, but for autonomous agents.
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":"aifinpay","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.
