A paid canary buys tools over the Robinhood Chain rail daily (facilitator: operator-configured) - uptime proven with real settlements, not pings.

Accept the Robinhood Chain CAIP-2 network (eip155:4663) in your 402 challenge, asset USDG (Global Dollar) - set PAYMENT_NETWORKS=…,robinhood plus your own ROBINHOOD_FACILITATOR_URL (the rail settles through an operator-supplied facilitator, not CDP or PayAI). Use @x402/evm for the server-side scheme (EIP-712 domain "Global Dollar", version "1"), or agent402-tollbooth (TOLLBOOTH_NETWORK=eip155:4663 TOLLBOOTH_ASSET=USDG). The full integration guide covers chain parameters and how to recognize a settlement on Blockscout. Then serve /.well-known/x402 - list it on /sell (free) and the index crawler picks it up; ranking is health-based, listing is free.
