Before the payment prompt
Read the quote.
Keep the choice.
Paste an x402 v2 PAYMENT-REQUIRED header or a v1/v2 JSON response. This page decodes the offered network, token, atomic amount, and pay-to address in your browser—without contacting the seller, connecting a wallet, or signing anything.
Paste the response
Accepted: the base64 value after PAYMENT-REQUIRED:, the complete header line, or a JSON payment-requirements object.
A parsed quote is only a seller's claim. This tool does not authenticate the endpoint, verify the recipient's control or balance, validate settlement, or tell you that a payment is safe.
