Wayback Machine snapshot

Look up a URL in the Internet Archive's Wayback Machine: returns the archived snapshot closest to an optional timestamp (default: most recent), with the snapshot URL, capture time, and archived HTTP status. Useful for citations, dead-link recovery, and checking what a page said at a point in time. URLs never archived return {available:false}.

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/archive-snapshot", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "url": "https://example.com"
  }),
});
