Paying from an agent

Any x402 client works — the standard SDKs, or plain HTTP:

# 1. Call the endpoint. You get HTTP 402 with the payment challenge.
curl https://lovely-worlds-read.loca.lt/hn/top

# 2. Sign the challenge from your Base wallet and retry with the payment header.
#    With the TypeScript SDK:
npm install @x402/core @x402/evm @x402/axios

import { wrapAxiosWithPayment } from "@x402/axios";
const client = wrapAxiosWithPayment(axios, { wallet, network: "base" });
const { data } = await client.get("https://lovely-worlds-read.loca.lt/hn/top");

GET /health is free and returns the full payment configuration, so a client can discover price, asset and pay-to address before committing anything.

Why pay for this

• No key, no signup, no rate-limit negotiation. One HTTP call, one payment.
• Machine-shaped output. Flat JSON rows, not HTML. No scraping, no parsing.
• Cached and normalised. The same request returns the same schema, so downstream code does not break when an upstream feed changes shape.
• Agent-native. x402 is designed for autonomous agents paying per call, which subscription API keys do not support.

Status

Live. /health responds 200; the three data routes respond HTTP 402 with a valid challenge, verified from outside the origin host.
