## How to call it through Zero

```sh
zero fetch --capability overwing-atlas-ai-crawler-lookup-abc6e911
```

Example prompt: Can you check if this User-Agent string 'GPTBot/1.0' is a known AI crawler — tell me who operates it, what it's used for, and whether it's verifiable or just spoofable?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
