Web discovery
- Structured results with heuristic credibility scores (0–1) per source class
- Usage and quota returned on every call — agents know what remains
- Tier-aware rate limits; cache-friendly for repeat queries
GET /v1/search?q=...Agent infrastructure · Experimental Beta
Lithtrix is a private workspace for your agent to search, browse, and remember — verified web discovery, server-side Browse on paid packs, durable JSON memory, and blob-backed documents. Metered per call, MCP-ready. One API key, Bearer auth everywhere.
We're in the founding period. Paid packs (Sprint / Mission / Deploy) unlock at 500 registered agents — this is when we'll consider the service stable enough to charge for. Until then, Spark trial is free to register and the infrastructure is live. Help us get to 500. Live registration stats load here when this page can reach the Lithtrix API.
👋 Hey, human. Lithtrix is built for agents — they self-register via API. If you want your agent on Lithtrix, point it at lithtrix.ai and let it sign itself up. That's the whole onboarding.
Same ltx_ Bearer token and billing tier across search, memory, and documents. Register once, use everything.
Web discovery
GET /v1/search?q=...Memory
PUT /v1/memory/{key}
GET /v1/memory/search?q=...Documents
POST /v1/blobs/{blob_id}/parse
GET /v1/blobs/search?q=...Discover → register → call any service with the same ltx_ token.
Machine-readable discovery
GET /v1/capabilities
Endpoints, auth shape, rate limits, and scoring rules. No authentication. Discovery version is 2.5.0 (includes tier_descriptions, pricing, commons, public GET /v1/community, and _lithtrix.usage with credits, tier_label, commons_*, community, storage lifecycle; plus served_by, feedback_url, and browse_url). Buy Sprint (or Mission / Deploy) to unlock Browse — see POST /v1/browse and the browser block in capabilities.
One-time enrollment
POST /v1/register
Create an agent row and receive a single-use API key. Store it like any other secret.
Optional referral_agent on POST /v1/register — set to another agent's UUID (their referral_code from GET /v1/me). Each validated signup credits that referrer +$0.50 (no cap; self-referral excluded). After you register, share your own referral_code from GET /v1/me so others can refer you.
Use the platform
GET /v1/search?q=...
Query the web; every row carries a credibility score and usage metadata.
PUT /v1/memory/{key}
Persist JSON; optional vector index for semantic queries on /v1/memory/search when enabled.
Every paid pack is a private workspace for your agent to search, browse, and remember — no monthly subscription. Spark is your trial; Sprint, Mission, and Deploy add credits via the API (POST /v1/billing/packs/checkout). Pack credits are usable for 90 days from grant (UTC).
Referrals: +$0.50 in credits per successful signup you refer (see agent guide →). Every referral gets us closer to 500.
