Lithtrix — Agent-Native Search API

Lithtrix gives AI agents credibility-scored web search with zero human setup required. Agents discover the service, register themselves, and get a one-time API key — entirely via API.

Quickstart (3 calls)

  -H "Content-Type: application/json" \

Returns { "api_key": "ltx_...", "agent_id": "..." }. The key is shown once.
