What it is

Free public REST API to search 8,000+ agent-readable sites, ranked by agentic readiness (llms.txt, OpenAPI, ai-plugin, MCP, structured API, robots.txt, schema.org). Useful for agents discovering what services exist that they can consume.

Meets criteria

• Public: yes — free, no auth required for read operations
• Persistent: yes — active since April 2026, daily-refreshed index, weekly auto-discovery from 8 sources
• Useful: yes — agent-first search is a new primitive with growing adoption; useful to anyone building agents that need to discover third-party services

Endpoints

• GET /api/v1/search?q=<query> — full-text search with category/signal filters
• GET /api/v1/site/{domain} — full agentic-readiness report for a domain
• GET /api/v1/stats — index-wide aggregates
• GET /badge/{domain}.svg — shields.io-style score badge
• Plus POST /api/v1/submit and POST /api/v1/monitor/register
