​
Authentication

All Stru AI APIs require authentication. Different APIs use different methods:

​
Memory API

Requires an API key in the X-API-Key header. Get your API key from app.stru.ai. 
X-API-Key: YOUR_API_KEY

​
Search, Mathcad, Excel APIs

Require a Bearer token generated from app.stru.ai: 
Authorization: Bearer YOUR_API_KEY
Get your API key by signing in to app.stru.ai and navigating to your dashboard.

​
Blogs API (Internal Only)

Uses internal proprietary authentication handled by the backend. Not available for external use.
