[FREE] Find out whether you can complete a payment to an x402 endpoint RIGHT NOW, before you sign anything. This answers a different question from check_x402_endpoint, which grades a seller's 402. This one runs the buyer's side of the handshake end to end: it reads the endpoint's terms, confirms they are complete enough to sign, calls the facilitator they name to see whether it actually answers /supported and /verify, prices the settlement against live Base gas and the Chainlink ETH/USD feed, and - when you pass a wallet - reads your on-chain balance to confirm it covers the price. Returns verdict.can_pay_now, a blocking list naming anything that genuinely stops the payment, and a warnings list for defects you can work around yourself. Two things it reports the way a buyer actually experiences them: * A missing or dead facilitator is a WARNING, not a blocker, because you can carry your own. * Gas is NOT needed to pay. Settling through a facilitator means signing an EIP-3009 authorization while the facilitator broadcasts, so the gas figures apply only if you broadcast the settlement yourself. endpoint_url is the full URL. method is the verb the endpoint expects, GET or POST. wallet is an optional 0x address; pass it to check funding and self-broadcast headroom. Free, unauthenticated, and it never sends a payment.
