In the chat, type @ followed by the MCP server name and your instructions, e.g., "@x402-farm extract the main content from https://example.com"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
64 pay-per-call APIs that AI agents pay for autonomously — via the x402 protocol (USDC on Base). No account, no API key, no subscription: the agent gets an HTTP 402, signs a micro-payment, retries, gets the data. Settlement is on-chain, per call, from $0.002.

Free taste, no wallet — every client gets 1 free call per day on any data route ≤ $0.01. Just call:
curl "https://api.x-402.online/v1/weather?city=Tokyo"
curl "https://api.x-402.online/v1/crypto/price?ids=bitcoin,ethereum&vs=usd"Paid, with any x402 client (funded USDC wallet on Base):
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";
const f = wrapFetchWithPaymentFromConfig(fetch, {
schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(privateKeyToAccount(PRIVATE_KEY)) }],
});
const r = await f("https://api.x-402.online/v1/search?q=x402"); // $0.003, settled on-chain
console.log(await r.json());Related MCP server: x402-agent-data
