Overview

The Ghost Content API provides read-only access to posts, pages, tags, authors, and settings published on a Ghost CMS instance — letting you pull your blog content into any frontend, app, or static site generator. A separate Admin API is available for write operations like creating or updating content. Each Ghost site exposes its own API endpoint with a site-specific Content API key.

💡

Beginner Tip

To use the Ghost API you need your own Ghost site (self-hosted or Ghost Pro) — there is no shared public endpoint. Find your Content API key under Ghost Admin > Integrations > Add Custom Integration. The base URL is always https://your-site.com/ghost/api/content/.

Available Data

Ghost data via REST API

  }
}

Implementation Example 

const url = "https://ghost.org/";
// 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 key query parameter is missing or the Content API key is wrong
✓ Append ?key=<your-content-api-key> to every request — find this in Ghost Admin > Integrations.
Empty posts array No posts have been published yet, or the requested filter does not match any content
✓ Make sure content is published (not draft) in Ghost Admin, and verify any filter parameters use Ghost NQL syntax.
CORS error from browser The Ghost site CORS settings do not allow requests from your frontend origin
✓ Add your frontend URL to the allowed origins in Ghost Admin settings, or use a server-side proxy to fetch content.
