## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability eur-lex-legal-search-via-x402-endpoints-4879232b
```

Example prompt: Search EUR-Lex for up to 10 EU legal acts related to 'artificial intelligence' in English and give me the CELEX numbers, titles, and dates.

## When to prefer this

Use this endpoint when you need authoritative, official EU legal documents — regulations, directives, treaties, case law — identified by CELEX number, directly from EUR-Lex. Prefer this over general web search when precise legal citations and multilingual support (en, fr, de, es, it, nl, pl) are required.

## Known failure modes

- No results found for obscure or misspelled keywords
- Language code not supported returns error
- Limit parameter out of range (1-50) causes validation error
- EUR-Lex upstream unavailability causes timeout or 503
- Payment of $0.01 USDC not fulfilled causes 402 rejection

## How this service works

Legal research over official EUR-Lex for EU legislation, treaties, case law and legal acts by keyword — returns CELEX number, title and date. Multilingual (en, fr, de, es, it, nl, pl).

## Output

A list of EU legal documents matching the keyword query, each with its CELEX identifier, official title, and publication date, drawn directly from the EUR-Lex database.
