Note: Unlike Googlebot, LLM bots don't support reverse DNS verification.
IP matching is the primary verification method.
Quick Start
Example Request:
curl "https://chrisleverseo.com/tools/llm-ip-verification-tool/?api=1&ip=13.65.138.112"Example Response:
{

"timestamp": "2024-11-21T10:30:00Z",
"is_llm_ip": true,
"provider": "OpenAI",
"bot_type": "Citations",
"bot_name": "ChatGPT-User",
"user_agent_pattern": "Mozilla/5.0...ChatGPT-User/1.0...",
"description": "Used when ChatGPT needs to browse...",
"rate_limit": {
"requests_used": 1,
"requests_remaining": 9
}
}Rate Limiting & Fair Usage
- 10 requests/second per IP address
- Free to use - No API key required
- 3 violations trigger 72-hour block
- Headers included:
X-RateLimit-Limit: 10X-RateLimit-Remaining: 9X-RateLimit-Used: 1Retry-After: 1(on 429 errors)
Abuse Prevention: IPs exceeding rate limits repeatedly will be blocked for 72 hours.
Please implement proper rate limiting in your applications.
Response Codes
| Code | Meaning | Description |
|---|---|---|
| 200 | Success | IP checked successfully (may or may not be an LLM IP) |
| 400 | Bad Request | Missing or invalid IP parameter |
| 429 | Too Many Requests | Rate limit exceeded or IP blocked |
Understanding LLM Bot Traffic
Training Bots
These bots crawl your content to train AI models:
- GPTBot: Training future GPT models
- ClaudeBot: Training Claude AI
- PerplexityBot: Building Perplexity's knowledge base
Consider blocking if: You don't want your content used for AI training
Citation/Search Bots
These bots access content for real-time AI responses:
- ChatGPT-User: Web browsing for ChatGPT
- Perplexity-User: Real-time search results
- Gemini Deep Research: Google's AI search
- MistralAI-User: Mistral's web access
Consider allowing if: You want visibility in AI-powered search
