How this service works
Hybrid semantic + keyword search over the embedded German law corpus from https://www.gesetze-im-internet.de/(Gesetze). Submit a natural-language `query` in a JSON body (`{"query": "..."}`) and receive the most relevant law chunks fused from vector and full-text retrieval, ranked by score. Returns JSON results with full legal reference, and matched text.The database has been tested against GerLeRB as golden dataset
Output
A ranked JSON array of law chunks, each containing the full legal reference (e.g. paragraph and law name from gesetze-im-internet.de), the matched text excerpt, and a relevance score derived from the hybrid vector + full-text retrieval fusion.
Example use cases
Contract defect liability research
“Can you search German law for anything related to 'Rücktritt vom Kaufvertrag wegen Mängeln' — withdrawal from a purchase contract due to defects — and show me the top 3 most relevant legal paragraphs with their official references?”
Tenant eviction rights lookup
“I need to know what German law says about 'Kündigung des Mietverhältnisses durch den Vermieter' — landlord termination of a rental agreement. Search the German federal law corpus and return the top 5 relevant passages.”
Data privacy compliance check
“Look up German law on 'Datenschutz und Einwilligung' — data protection and consent — and retrieve up to 10 relevant law sections with their references so I can check compliance requirements.”
Technical details
Endpoint
POSThttps://amalgam.cc/api/lawsearch/searchWhen to prefer
Choose this endpoint when you need to search German federal law text with both semantic understanding and keyword precision — especially when the user asks a natural-language legal question in German or about German law, and you need specific statutory passages with official references. Prefer this over generic web search when you need structured, ranked legal excerpts directly from the gesetze-im-internet.de corpus rather than general web commentary.
Side effects
- Empty or vague query returning low-relevance results
- Query in a language other than German may yield poor matches since corpus is German
- Requesting more than 50 results returns an error (maximum limit is 50)
- Network timeout or service unavailability returning HTTP 5xx
- Query too broad returning only superficially related statutes
