Nero Labs Agent Tools

Compares an old and a new list of JSON rows by a key field and returns what was added, removed and changed, with the old and new value of every changed field. Use it to spot new leads, price changes or deleted items between two scrapes. Up to 500 rows a side. $0.001 per new row sent (old rows free), $0.002 minimum. Same engine as nerolabs/dataset-diff-detector.

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://x402-agent-tools.nerolabs.workers.dev/data/diff", { method: "POST" });
console.log(await res.json());
