Nero Labs Agent Tools

Joins two lists of JSON rows on one or more key fields, like a VLOOKUP or SQL join: inner, left, right, full or anti. Keys match exactly, or normalized (case, spacing and number-as-text differences ignored). Returns joined rows plus match counts and unmatched rows. Up to 500 rows a side. $0.002 per left row sent (right rows free), $0.002 minimum. Same engine as nerolabs/dataset-join-merge.

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/join", { method: "POST" });
console.log(await res.json());
