Route Match

Compare the URL your client called with the resource.url declared in an x402 HTTP 402 challenge. Catch route mismatches before a buyer or strict client does.

Local-only parsing. This page does not fetch either URL, upload your input, connect a wallet, sign, or send a payment. Avoid pasting secrets, cookies, or private data.

URL the client actually requested HTTP response, JSON challenge, or PAYMENT-REQUIRED header

What it checks

Compares origin, path, and query string between the requested URL and the challenge's declared resource URL.
Parses common x402 v2 PAYMENT-REQUIRED headers and JSON challenge bodies.
Shows payment options the challenge declares, including network, asset, amount, and recipient when present.

Limits

A match is not a safety verdict. This tool cannot verify the recipient, token contract, network, facilitator, quote freshness, settlement, or whether a paid endpoint delivers what it promises. Confirm the provider and amount independently before authorizing a payment.

This checker never contacts the URL you enter. It parses only the text already in the page.

Optional support

If this saved you time, you may send a voluntary 1 USDC tip on Base. No purchase or wallet connection is required.
