Structured EU regulatory compliance data for developers

## What is Law4Devs? Law4Devs is a REST API and SDKs that turns EU regulatory texts into structured, queryable JSON. Instead of reading 300-page PDF regulations, your application queries articles, recitals, requirements, compliance deadlines, and tags via simple HTTP calls. **19 EU frameworks** — CRA, GDPR, NIS2, DORA, AI Act, eIDAS 2.0, DSA, DMA, Data Act, MiCA, and more. How It Works Zero-dependency. `pip install law4devs` Zero-dependency. `npm install law4devs` Composer package. `composer require law4devs/law4devs` Zero-dependency. Maven · Java 17+ pub.dev · Dart 3+ · Flutter & CLI crates.io · Rust 1.85+ · Tokio async Interactive docs for all 21 endpoints. All 19 EU regulations, with CELEX numbers.
