01 — WHY THIS API

Legal intelligence that plugs in.

01

OpenAI-compatible

A drop-in base-URL swap. Standard chat completions, SSE streaming, and the usual usageobject reporting exactly what you're billed — your existing SDKs, tooling and retries just work.

02

Grounded in real law

Answers are generated from indexed legal sources through the snowLEX retrieval pipeline — statutes, cases and regulations, not blog posts. Finnish law (Finlex) has the deepest coverage today, with EU and Nordic material indexed progressively. Ask with include_sources and the API returns the citations behind every answer.

03

Token-metered, prepaid

Load a balance and pay per token. No subscriptions, no minimums, no expiry — every charge itemized per request in the console.
