Code Examples

Node.js

// Monitor a competitor's pricing page for changes
const monitor = await fetch("https://api.snapapi.tech/v1/monitors", {
  method: "POST",
  headers: {
    "X-API-Key": "YOUR_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    url: "https://competitor.com/pricing",
    name: "Competitor Pricing Watch",
    interval: 60,
    webhook_url: "https://yourapp.com/webhooks/competitor-change"

const { id } = await monitor.json();
// When pricing changes, your webhook receives:

//   "url": "https://competitor.com/pricing",
//   "change_detected": true,
//   "diff_summary": "Price changed from $49 to $59 on Pro plan",
