import { Fewsats } from 'fewsats';

// Configure the SDK
const client = new Fewsats({
  apiKey: process.env.FEWSATS_API_KEY,
});

// Make HTTP request to external service
const response = await fetch('https://some-api.com/endpoint');

// Handle HTTP 402 payment required error
if (response.status === 402) {
  // The response contains information about available offers
  const data = await response.json();
  const offerId = data.offers[0].id; // Take first offer
  const resp = await client.payOffer(offerId, data);
