check_x402_payability
For x402 sellers: can a real buyer actually pay this endpoint? Sends one payment signed by a fresh unfunded key through the endpoint's server and facilitator. Payable endpoints fail only on balance; anything else is reported with the exact reason (schema, description over 500 chars, EIP-712 domain, price over the $1 default client cap, paywall not enforcing).
