Accept the Arbitrum CAIP-2 network (eip155:42161) in your 402 challenge - the PayAI facilitator verifies and settles, gas sponsored. Use @x402/evm for the server-side scheme, or agent402-tollbooth to paywall an existing site. Then serve /.well-known/x402 - the index crawler lists you automatically; ranking is health-based, listing is free. Want a guaranteed crawl? Open a seed request.
