## 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 invoket-legal-diff-batch-b12788d2 -d '<json body>'
```

Example prompt: Show me what changed in French civil code articles L1234-1 and L5678-2 between January 1 2024 and June 20 2026 — give me the word-level diff so I can see exactly which words were added or removed.

## When to prefer this

Use this endpoint when you need to compare multiple French legal article texts across two specific dates in a single batch call, receiving structured word-level diffs. Prefer this over single-article diff endpoints when processing multiple articles at once to save on per-call costs. Ideal for compliance monitoring, legal audits, or legislative change tracking workflows where precise textual changes matter.

## Known failure modes

- Invalid article code returns error or empty results
- Date range with no version boundary returns changed=false with identical text
- Incomplete coverage (coverage.complete=false) when full text is unavailable
- Payment failure via x402 if USDC balance is insufficient
- Malformed batch input returns 400 error
- Article not found in the legal database returns empty results array

## How this service works

Before your agent re-runs a contract review or due diligence after time has passed: a structured diff of the consolidated text — word-level segments plus a git-style unified patch — for up to 50 French or EU article references, each between its own two dates, in one call, from the official LEGI and EUR-Lex datasets. Covers 12 major French codes and statutes and key EU acts (GDPR, DSA, AI Act, MiCA and more).

## Output

A JSON object containing an array of per-article diff results. Each result includes the article code, from/to dates, from/to version metadata (version ID, etat, date_debut, date_fin), a boolean indicating whether the text changed, word-level diff segments (op: equal/insert/delete plus text), added/removed word counts, a unified diff string, and a coverage.complete flag. Also includes provenance metadata with source, fetched_at, and freshness info.
