Factline

Use when an agent calls Factline often: one 2 USDC x402 payment returns an API key with 1,250 credits (20% cheaper than paying per call), valid 12 months, bound to the paying wallet. Send it as x-api-key on any paid endpoint. One settlement instead of many small ones. GET or POST, no parameters.

Call it from code

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://factline.dev/v1/credits/topup", { method: "GET" });
console.log(await res.json());
