# UNE — Unified Norms Engine (AtoA)
> Deterministic cross-border legal computation, customs clearance, maritime carbon compliance, and sanctions screening infrastructure for autonomous agents (M2M), LLMs, and ERPs.

## Core Philosophy
UNE provides zero-entropy computation nodes. Unlike probabilistic LLMs that hallucinate regulatory interpretations, UNE delivers authoritative, strict statutory cutoff deadlines, cryptographic notices, and exact financial calculations executed in constant time (< 5ms). Every output includes an immutable SHA-256 state proof for auditability.

## Universal Access & Monetization
- **Discovery Tier (Free):** Public anonymous access, rate-limited. Ideal for testing and non-critical queries.
- **Developer Pass (29 €):** Universal API Key (sk_live_...) valid across all 6 nodes. 50,000 requests.
- Purchase: https://legal.une.education/checkout.php?pack=dev_50k&redirect=1
