Integrating ZeroClick involves three steps:
1

Get ZeroClick offers

Retrieve offers via REST API
2

(Optional) Turn on Signal Collection

Collects user context in the background to generate more relevant offers
3

Track impressions

Use the REST API from the user’s device to track offer impressions.

​
Get Offers

Fetch offers via HTTP and render them however you want. 
const response = await fetch("https://zeroclick.dev/api/v2/offers", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "x-zc-api-key": "your-api-key"
  },
  body: JSON.stringify({
    method: "server",
    ipAddress: clientIpAddress,
    query: "best running shoes"
  })
});

const offers = await response.json();
// Render in your UI

​
Signal Collection

Turn on Signal Collection to improve offer relevance. ZeroClick learns user preferences in the background and delivers more personalized offers. How it works:
  1. Connect the MCP Signal Server to your application
  2. As users interact, the LLM silently broadcasts preference signals
  3. When you request offers, ZeroClick uses these signals to personalize results

​
Track Impressions

After displaying offers to users, call the impressions endpoint to record what was shown. This is required for analytics and revenue attribution. 
await fetch("https://zeroclick.dev/api/v2/impressions", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    ids: offers.map(offer => offer.id)
  })
});
Impression requests must originate from the end user’s device, not your server. Requests will be rate limited per IP.
