43 production products/endpoints serving prediction markets, sports odds, financial data, regulatory filings, weather, FX rates, crypto prices, QR codes, timezones, utility wrappers, MCP tools, AI sentiment, and more — paid via x402 micropayments on Base mainnet, with a small free tier on selected utility endpoints.

Quick start

npm install @x402/fetch viem

import { fetchWithPayment } from '@x402/fetch';
import { createWalletClient, http } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';
import { base } from 'viem/chains';

const account = privateKeyToAccount('0xYOUR_PRIVATE_KEY');
const wallet = createWalletClient({ account, chain: base, transport: http() });

const res = await fetchWithPayment('https://api.devdrops.run/api/fx/latest', { wallet });
