How this service works
AIScan audits any website for AI visibility in 60 seconds. 4 scores: AEO, GEO, Agent Readiness, MCP Readiness. Plus Brand Visibility: how often AI actually names your brand. The only scanner with MCP Readiness.
Output
Returns a capability string confirming the check was executed, plus the analyzed site URL and payment settlement info. The core result indicates whether the llms.txt check was performed — the capability field describes what was run.
Example use cases
Example prompt
“Can you check if openai.com has an llms.txt file set up and whether it's properly configured for AI agent discoverability?”
Technical details
Endpoint
POSThttps://api.getaiscan.app/api/agent/check_llms_txtWhen to prefer
Use this endpoint specifically when you need to determine whether a website has an llms.txt file in place — a key signal of MCP and AI agent readiness. Choose this over a general AI visibility audit when you only need the llms.txt check specifically, not a full 4-score AEO/GEO/Agent/MCP audit.
Side effects
- Invalid or malformed URL returns an error
- Site is unreachable or times out during the check
- Payment of $0.07 USDC not settled, resulting in 402 response
- URL missing scheme (e.g. missing https://) causes rejection
- Rate limiting or server errors on the target domain prevent analysis
