How this service works
Overwing Atlas: identify a User-Agent string against a registry of AI crawlers, fetchers and browser agents. Returns the claimed agent, operator, purpose, verification method (Web Bot Auth vs spoofable) and a trust note. GET ?user_agent=... $0.001 USDC.
Output
Returns structured information about the matched AI crawler or agent including: the claimed agent name, operator organization, stated purpose, verification method (Web Bot Auth vs spoofable), and a human-readable trust note. If the User-Agent is not in the registry of 241 agents, the response indicates no match.
Example use cases
Gating AI crawler access to content
“I'm getting traffic from a bot with User-Agent 'ClaudeBot/1.0' — can you look it up and tell me if it's a real AI crawler, who runs it, and whether I can actually trust it or if anyone could spoof it?”
Auditing server logs for AI bots
“I found this User-Agent in my server logs: 'PerplexityBot/1.0'. Can you check if it's in the AI crawler registry and tell me its purpose and whether it uses Web Bot Auth or is just spoofable?”
Bot policy enforcement for a web app
“Before I decide whether to block or allow this request, can you identify this User-Agent 'Applebot/0.1' — I need to know the operator, what it's crawling for, and how trustworthy it is?”
Technical details
Endpoint
GEThttps://overwing.ai/api/x402/atlas/lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to classify incoming User-Agent strings as AI crawlers specifically, especially when you need trust-level context (Web Bot Auth vs spoofable) and operator identity — not just a generic bot-detection yes/no. Ideal for AI-aware access control, log auditing, or bot policy enforcement where knowing the difference between a verified AI agent and a spoofed one matters.
Side effects
- User-Agent not found in the 241-agent registry — returns no match or unknown status
- Malformed or empty User-Agent string — may return an error or empty result
- Spoofed User-Agent that matches a known bot name — flagged as spoofable rather than verified
- Network or payment (x402) failure — request not completed
- Rate limiting or API quota exceeded
