How this service works
HALOWERK rechtwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
A structured response containing all equivalent identifiers for the legal act (CELEX, ELI URI, EUR-Lex URI, Cellar URI, etc.), a list of available language expressions (e.g. EN, FR, DE), and for each expression the available manifestation formats (PDF, HTML, DOCX, etc.) with their respective download links — organized around the FRBR-inspired distinction between work (language-independent act), expression (language version), and manifestation (file).
Example use cases
GDPR identifier cross-reference
“I need to find every equivalent identifier for the GDPR — I have the CELEX number 32016R0679 but I also need the ELI URI and EUR-Lex URL, plus a list of all the languages it's officially published in.”
Locating a directive in a specific language
“I have an ELI URI for an EU directive and I want to know if it's available as a PDF in French — can you resolve the identifier and show me all the available language expressions and their file format manifestations?”
Building a legal citation resolver
“I'm building a compliance tool and I need to normalize EU legal act references — take this EUR-Lex URL for Directive 2018/2001 and give me all the equivalent identifiers like CELEX and ELI so I can store them consistently.”
Technical details
Endpoint
POSThttps://recht.halowerk.com/v1/eu-law-resolver?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to cross-reference or normalize EU legal act identifiers across systems — particularly when moving between CELEX numbers, ELI URIs, EUR-Lex URLs, and Cellar URIs. It is specifically designed for the EU Publications Office's FRBR-based data model, making it the right choice when you need to enumerate language versions or file format manifestations of EU legislation. Prefer this over generic legal search tools when you already have one identifier and need the others, or when building multilingual legal compliance pipelines.
Side effects
- Unknown or malformed identifier returns an error indicating the act could not be resolved
- Identifier refers to an act not yet indexed in EUR-Lex/Cellar, returning no results
- Ambiguous identifier that matches multiple acts may return an error or require disambiguation
- Network or upstream EUR-Lex/Cellar API unavailability may cause timeout or 5xx errors
- Providing a non-EU legal act identifier (e.g. national law) will not be resolved
