Overview

Intelligence X is an OSINT search engine API that lets you search historical and leaked data including emails, domains, IPs, URLs, and more from the dark web and other sources. It is designed for security researchers and investigators who need to pivot across data sources quickly. Access requires an API key and usage is metered based on the plan you choose.

💡

Beginner Tip

Searches are asynchronous — first submit a search to get a search ID, then poll the results endpoint until the search completes. Always handle the "still searching" state in your code to avoid processing incomplete data.

Available Data

Intelligence X data via REST API
JSON-formatted response data
Requires API key authentication

Example Response

JSON Response 
{
  "status": "success",
  "data": {
    "result": "Data from Intelligence X",
    "description": "Perform OSINT via Intelligence X",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

id Unique search ID used to retrieve results via the polling endpoint.
status Search status code: 0 = success, 3 = still searching.
records Array of matching records found across indexed data sources.
records[].name File or source name where the match was found.
records[].date Date the record was indexed by Intelligence X.

Implementation Example 

const url = "https://github.com/IntelligenceX/SDK/blob/master/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

401 Unauthorized The x-key header is missing or the API key is invalid.
✓ Register at intelx.io to obtain an API key and pass it in the x-key header of every request.
Search returns no results immediately Intelligence X searches are asynchronous and results are not instantly available.
✓ Use the search ID from the initial response to poll the /intelligent/search/result endpoint until status indicates completion.
402 Payment Required Your account has exhausted its search credits or the requested feature requires a higher plan.
✓ Check your credit balance in the Intelligence X dashboard and upgrade if necessary.
