Image crop

$0.005 per call · USDC via x402 · POST /api/image-crop

Crop an image to a pixel box, and/or rotate (90/180/270) and flip it — applied in that order. Send a public image URL or a base64 image. Returns the result as binary, or as a JSON data URI with dataUri:true. Deterministic.

curl -i -X POST https://agent402.tools/api/image-crop \
  -H "Content-Type: application/json" \

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/image-crop", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "url": "https://raw.githubusercontent.com/ianare/exif-samples/master/jpg/Canon_40D.jpg",
    "left": 10,
    "top": 10,
    "width": 60,
    "height": 40,
    "dataUri": true
  }),
});
Wallet-only. This tool reaches the network/browser/storage, so it is paid in USDC via x402 (no proof-of-work tier).
