API Reference

Welcome to the Nexus API Reference. This section contains detailed documentation for all available API endpoints.

Base URL

All API requests should be made to:

https://api.nexusgpt.io/api/public

The Nexus API provides the following endpoints:

POST /sessions - Initialize a new chat session

POST /messages - Send messages to an active session

GET /sessions/ - Retrieve session information

GET /messages - Get conversation history with pagination

All endpoints require authentication via API key in the api-key header:

api-key: YOUR_API_KEY

All endpoints return JSON responses with consistent structure:

{
  "success": true,
  "data": {
    // Endpoint-specific response data
  }
}

For a comprehensive integration guide including authentication, error handling, and best practices, see the Nexus API Integration Documentation.
