Lithtrix — 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 — 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 — tier_descriptions, pricing, commons, GET /v1/community, extended _lithtrix.usage + community on authenticated responses) Pricing: docs/pricing.mdx — Spark trial, Sprint / Mission / Deploy packs, $0.005 per-call rates, auto top-up (Mintlify nav Getting Started → Pricing).
