Overview

The StackExchange API gives you programmatic access to all Stack Overflow and Stack Exchange network sites, including questions, answers, users, tags, and comments. You can use it without authentication for read-only access, making it easy to pull developer Q&A content into your own apps. OAuth is needed only for write operations like posting answers or voting.

💡

Beginner Tip

Always include a site parameter (e.g., site=stackoverflow) in your requests, and add a key parameter with your registered app key to get a higher daily request quota.

Available Data

Use case: Integrate q&a forum for developers data into web and mobile applications
StackExchange data via REST API
JSON-formatted response data
Requires OAuth authentication

Example Response

JSON Response 
{
  "status": "success",
  "data": {
    "result": "Data from StackExchange",
    "description": "Q&A forum for developers",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

items Array of question objects matching your query
items[].question_id Unique numeric identifier for the question
items[].title Title text of the question
items[].score Net vote score (upvotes minus downvotes) for the question
has_more Whether additional pages of results exist beyond the current page
quota_remaining Number of API requests remaining in your current daily quota window

Implementation Example 

const url = "https://api.stackexchange.com/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "Authorization": "Bearer YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

400 bad_parameter - site is required The site query parameter is missing from the request
✓ Add &site=stackoverflow (or another network site name) to every request URL
502 throttle_violation Exceeded the daily request quota (300/day without a key)
✓ Register a free app at stackapps.com to get an API key, which raises the quota to 10,000 requests/day
Empty items array Filter or date range returned no matching results
✓ Broaden your query parameters — remove strict date filters or use a popular tag like javascript to confirm the API is working
