Welcome to the LLMGenerator API documentation. Our API provides programmatic access to the core features of LLMGenerator, allowing you to integrate llms.txt generation and management directly into your applications.

​
Base URL

All API endpoints are relative to the following base URL: 
https://api.llmgenerator.com/api/v1

​
Authentication

The LLMGenerator API uses API keys to authenticate requests. You can create and manage your API keys in Settings → API Keys. All authenticated requests must include an Authorization header with your API key as a Bearer token. 
Authorization: Bearer YOUR_API_KEY
Keep your API keys secure. Do not share them in publicly accessible areas such as GitHub, client-side code, etc.

​
Generation Methods

The API supports two distinct generation methods:
MethodDescriptionCredit Cost
SimpleFast generation using page metadata. Best for quick results.1x
EnhancedAI-powered generation with improved titles and descriptions.2x
You can specify the method using the generationMethod parameter in the /generate endpoint. Free plan users can only use the simple method.

​
Credit System

API usage is tracked through credits:
  • Simple generation: Base credit cost per URL processed
  • Enhanced generation: 2x credit multiplier for AI processing
  • Full text: Additional credits for including full page content
Check your balance using the /credits/balance endpoint.

​
Rate Limiting

API requests are rate-limited based on your subscription plan. If you exceed the rate limit, you will receive a 429 Too Many Requests response. The response headers contain rate limit information:
  • X-RateLimit-Limit: Maximum requests per minute
  • X-RateLimit-Remaining: Requests remaining in current window
  • X-RateLimit-Reset: Time when the window resets (UTC epoch seconds)

​
CORS Support

Public file endpoints (/file/:siteId) support CORS and can be accessed directly from browsers. These endpoints don’t require authentication.

​
Errors

The API uses standard HTTP status codes:

400Bad request (validation error)
401Unauthorized (invalid/missing API key)
403Forbidden (insufficient permissions)
404Resource not found

}
