AgentSearch HTTP API is one of 6 APIs that [Luther Systems](https://apis.io/providers/luthersystems-com/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Agents, Agent Discovery, and Search. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and rate-limit docs.

Public, no-auth HTTP API for AgentSearch, Luther Systems' daily-scored index of AI agents and MCP servers, at https://agentsearch.luthersystems.com. Six operations described by a provider-published OpenAPI 3.1.0 (POST /api/search, GET /api/agent/{name}, POST /api/found-agent, GET /api/browse, GET /api/stats, GET /.well-known/agent.json) that the spec itself says mirrors the @luthersystems/agentsearch MCP server; POST /api/submit-agent is documented on /api-docs but not in the spec. Read-only, best-effort ~60 requests/minute/IP, MIT-licensed surfaces on GitHub.
