Context layer

Developers & AI tools

overview.legal is built to be read by machines as well as people: 8,000+ documents of EU data protection law — legislation, case law, 3,300+ enforcement decisions with fine metadata, guidance and news — cross-linked by topic and citation, and exposed as context bundles, a REST API and an MCP server. Free to use; get an API key for higher limits.

Context bundles (markdown)

One curated, cited markdown file per topic or per law — drop it into your LLM's context, RAG store or project knowledge:

  • GET /topics/{slug}/context.md — topic bundle: editorial overview + key law text + case law + enforcement + guidance. Example: /topics/consent/context.md (?lang=nl for Dutch)
  • GET /laws/{law}/context.md — full text of a law, cited per provision. Example: /laws/gdpr/context.md — law slugs: gdpr, avg, ai-act, dsa, nis2, uavg, …
  • GET /laws/{law}/{article}/context.md — focused per-article bundle: the provision text, related recitals, citing case law, enforcement stats + top fines, guidance and related topics. Example: /laws/gdpr/art-6/context.md
  • GET /llms.txtsite summary for AI assistants

MCP server

Connect Claude, or any MCP-capable tool, directly to the corpus. Streamable HTTP, stateless, no auth required (optional Authorization: Bearer olk_… for higher limits):

{
  "mcpServers": {
    "overview-legal": {
      "type": "http",
      "url": "https://overview.legal/api/mcp"
    }
  }
}

Tools exposed:

  • search_legal — hybrid search across all content types, results carry the matched passage + topic slugs; mode scopes by jurisdiction (eu default, nl, all), court narrows case law to cjeu or national
  • build_overview — CJEU-first, authority-ranked overview of a topic or question (leads with CJEU/EU courts + EDPB, then national case law), with verbatim quotes for the leading judgments
  • get_document — one document with topics + citation counts; long judgments/decisions are split into ¶/§ sections — pass query to get the matching passages (quotable verbatim) instead of a top-of-document slice
  • get_article — verbatim text of one law article by law + article number (no id guessing)
  • verify_quote — anti-hallucination check: confirm a citation (e.g. a C-…/… reference or ECLI) exists, or that a passage appears verbatim
  • get_citations — citation graph (law articles ↔ cases ↔ decisions)
  • list_topics — find topic slugs by name (EN/NL) to feed get_topic_context
  • get_topic_context — the full topic context bundle as markdown
  • enforcement_stats — GDPR fine statistics by article, country, authority, year

REST API

EndpointWhat it does
GET /api/hybrid-search?q=…Hybrid full-text + semantic search. Params: types, topics, language, mode (eu|nl jurisdiction scope), limit, offset
GET /api/similar?id=…Semantically similar documents (pgvector)
GET /api/citations/{id}Citation graph for a document
POST /api/askRAG answer with citations. Single-shot {"q": "…"}, or grounded/conversational {"messages": […], "source_ids": [1,2], "language": "nl"}source_ids are preferred sources, hybrid search tops up (quota: 5/day anonymous, 25 with account, 100 with API key)
GET /api/statsLive corpus counts
curl "https://overview.legal/api/hybrid-search?q=consent+cookies&types=case-law,enforcement&limit=5" \
  -H "Authorization: Bearer olk_YOUR_KEY"
curl -X POST https://overview.legal/api/ask \

API keys & limits

  • Anonymous: 60 requests/min per IP on search/citations, 120/min on similar.
  • With a free API key: 300 requests/min per key, usage visible in your account.
  • Keys are free while the platform grows. Heavy or commercial integrations: mention it via the contact below so we can plan capacity (a paid tier with SLAs will follow demand).

Fair use

  • Content is aggregated from official sources (EUR-Lex, curia.europa.eu, rechtspraak.nl, EDPB, national DPAs) and organized by overview.legal; it is legal information, not legal advice.
  • Attribute answers and datasets to overview.legal with a link to the canonical URL.
  • No bulk scraping of HTML pages — the bundles and API exist so you don't have to.
