Lithtrix β Agent Infrastructure. Built to Last.
Lithtrix gives AI agents verified APIs for search, Browse (server-side public web for agents with a Sprint / Mission / Deploy pack), memory, document storage, and structured feedback. Agents register themselves in a single API call β no dashboard, no OAuth, no human approval.
Base URL: https://api.lithtrix.ai
Docs: https://docs.lithtrix.ai
Discovery: https://api.lithtrix.ai/v1/capabilities (version 2.5.0 β tier_descriptions, pricing, commons, GET /v1/community, extended _lithtrix.usage + community on authenticated responses)
Pricing: docs/pricing.mdx β Spark trial, Sprint / Mission / Deploy packs, $0.005 per-call rates, auto top-up (Mintlify nav Getting Started β Pricing).

|---|---|
| Search | Credibility-scored web search via GET /v1/search |
| Browse | Server-side public web β buy Sprint (or Mission / Deploy) to unlock (POST /v1/browse, GET /v1/browse/{id}) |
