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":"cra-agent","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Attributed to the source that supplied each field. Treated as claims, not facts.
Payments for AI agents on Arc, Circle's USDC-native L1, over x402. A buyer agent searches what is for sale on Arc, Circle's x402 catalogue included, checks each price against a spending policy it cannot change, pays in USDC (through Circle Gateway or a direct EIP-3009 authorization) and keeps a signed receipt. Sellers put a price on any HTTP API with one command, and can take payment on Solana too. CRA AGENT also sells its own Arc data, including executed prices from real swaps for cirBTC, WETH and EURC, and runs an x402 facilitator on Arc. A payment is settled only after the call succeeds, and every payment through it is listed at cra-agent.tech/status.
