import { wrapFetchWithPayment } from 'x402-fetch';
import { privateKeyToAccount } from 'viem/accounts';

const account = privateKeyToAccount(process.env.X402_WALLET_PRIVATE_KEY as `0x${string}`);
const fetchWithPay = wrapFetchWithPayment(fetch, account);

const res = await fetchWithPay('https://api.pdfasyougo.com/v1/pages/reverse', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ file: 'https://example.com/scanned-backwards.pdf' }),
});
console.log((await res.json()).output.url);

Response

{
  "output": {
    "url": "https://files.pdfasyougo.com/o/5e1b…?token=…",
    "expires_at": "2026-06-29T12:00:00Z",
    "pages": 12,
    "bytes": 98304
  },
  "operation": "pages.reverse",
  "cost": "0.05 USDC"
}

Notes

• The whole document is reversed; there are no parameters to select a subset.
• Page content and rotation are preserved — only the order changes.

Tip

Need to reorder only part of a document? Combine Extract pages and Merge — each step is its own $0.05 operation.
