Sign in with your wallet to try an endpoint straight from the browser.
Pay with an agent
Any MPP or x402-compatible client works. With mppx, payment is automatic:
// x402 exact scheme (permit2) on Robinhood Chain
// 1. GET the endpoint, read the payment-required header (base64 JSON)
// 2. Sign PermitWitnessTransferFrom against Permit2 for the advertised offer
// (spender = x402ExactPermit2Proxy, witness.to = merchant wallet)
// 3. Retry with the payment-signature header; settlement tx arrives
// in the payment-response header
