# Strale Beacon

> Free agent-readiness scanner. 32 automated checks across 6 categories. Scan any URL and see what AI agents can discover, understand, and do with your product.

Strale Beacon scans publicly accessible URLs and produces detailed agent-readiness reports. It checks for llms.txt, OpenAPI specs, MCP endpoints, A2A agent cards, structured data, authentication documentation, and 26 other signals that AI agents look for.

## Scan API

GET https://scan.strale.io/api/report/{slug}
