The questions every data team asks first.

Short answers, with the evidence one click away.

  • Why not scrape EUR-Lex ourselves?

    The text is free; the work is not. This is 16 jurisdictions and 20+ publication formats parsed to article level, 800k+ citation edges resolved and typed, withdrawals tracked as tombstones, and the reuse terms documented source by source. You get it as one schema, maintained monthly.

    Build vs buy, in detail
  • Is it licensed for AI training?

    Every record carries its upstream source, licence and attribution. Rights for RAG, fine-tuning, pre-training and model weights are set by tier in one licence agreement. What cannot be licensed for AI, such as UK case law, is left out and explained.

    Rights matrix
  • How fresh is it?

    Monthly delta snapshots: new and changed records as upserts, withdrawn ones as tombstones. The current snapshot runs to 12 November 2026. Version history records when each change was observed.

    Version history
  • What formats?

    Apache Parquet (zstd, about 512 MB shards) and gzip JSON Lines with identical fields. Each snapshot ships MANIFEST.json with a SHA-256 per shard, a datasheet and the attribution file; Croissant metadata is public.

    Formats and files
  • How is it delivered?

    By signed download or straight to your bucket. Custom cuts per jurisdiction, language, date range or document type are prepared within 5⁠–⁠6 business days.

Collection: Arieta Labs collected the upstream data through publishers' documented APIs, open-data dumps and official websites. Documents that a source lists for removal (for example takedowns listed in robots.txt) and documents withdrawn by the source are removed and delivered as tombstones. A per-source record of terms and access channels is supplied with each snapshot.

Personal data: national court decisions are not in this snapshot’s files; they are delivered separately, only after personal-data masking. CJEU case law is included as published by the Court. Documents withdrawn by their source are delivered as tombstones and deleted by the licensee.

Copyright and reuse: each record carries its source, licence and attribution. Reuse of EUR-Lex content is permitted under the EUR-Lex legal notice (Commission reuse policy, Decision 2011/833/EU); CJEU case law under the CURIA copyright notice; national texts under the terms listed per source. UK case law is not included: the Open Justice Licence does not cover computational analysis.

FAQ

Questions buyers ask first.

What is Arieta Data?

Arieta Data is a licensable dataset of European law for AI training, retrieval and evaluation, from Arieta Labs Ltd, the company behind LexAPI. It contains EU legislation, CJEU case law and national legislation from 15 countries, parsed to article level, with version history and a typed citation graph. As of the November 2026 snapshot the corpus holds 3.9M+ documents, of which 410k+ documents (4M+ articles) are ready to license.

Can I legally train an AI model on EUR-Lex data?

EUR-Lex’s legal notice allows reuse of the legal documents it publishes, including commercially, with acknowledgement of the source; Commission documents follow the Commission’s reuse policy (Decision 2011/833/EU) and CJEU case law the CURIA copyright notice. National sources each have their own terms, and UK case law needs a separate licence for computational analysis. Arieta Data documents the terms per source. See Is EUR-Lex data licensable for AI training?. Not legal advice.

Is national case law included?

Yes. CJEU case law is included as published by the Court. National case law is included too (3.4M+ decisions as of the November 2026 snapshot): court decisions name or pseudonymise people, so they are delivered with personal data masked, including magistrate and clerk names for France. Tell us which courts you need, subject to licence terms. UK case law is not offered: the Open Justice Licence does not cover computational analysis, and the separate licence from The National Archives cannot be passed on.

What formats, delivery and updates do you offer?

Apache Parquet (zstd, sharded at about 512 MB) and gzip JSON Lines with the same fields, by signed download or to a bucket you control. Each snapshot ships MANIFEST.json with SHA-256 checksums per shard, a datasheet and LICENCES.md. Updates are monthly deltas with upserts and tombstones.

How fast can we get the data?

The free sample downloads now, with no sign-up. Custom cuts per jurisdiction, language, date range or document type, and licensed deliveries, are prepared within 5⁠–⁠6 business days. We reply within one business day. See Request access.

How much does it cost?

Sample records are free to download. Research / Startup licences start at €7,000 a year, Commercial at €18,000 a year, and Foundation / Lab at €50,000 a year (custom terms). Commercial and Foundation / Lab include a perpetual right to the snapshots you received. See Licensing.
