## 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 vextorium-boe-disposici-n-lookup-2a753281 -d '<json body>'
```

Example prompt: Can you look up BOE item BOE-A-2026-20025 and give me its official metadata — rank, department, dates, repeal status — plus an AI summary in Spanish explaining what it establishes, who it affects, and any deadlines?

## When to prefer this

Choose this endpoint when you need authoritative metadata and a plain-language AI summary for a specific Spanish BOE (Boletín Oficial del Estado) item identified by its BOE ID. It is ideal for legal research agents, compliance tools, or public administration workflows that need to quickly understand a specific Spanish regulation or disposition without reading the full official document. Prefer this over generic web search when you need structured fields (repeal status, department, dates) and a reliable AI explanation in Spanish from a local model.

## Known failure modes

- Invalid or non-existent BOE ID returns null fields or an error response
- BOE identifier format incorrect (must match pattern like BOE-A-YYYY-NNNNN)
- AI summary unavailable if local model is temporarily offline
- Slow response if the item is not cached and requires fetching from source
- Rate limiting or payment failure if x402 payment is not completed

## How this service works

Official data of any Spanish BOE item (rank, department, dates, subjects, repeal status) plus a clear AI summary in Spanish from a local model: what it is, who it affects, what it establishes and its deadlines.

## Output

Returns a JSON object with the BOE item's official rank (rango), issuing department, disposition date, publication date, effective date (fecha_vigencia), official number, repeal status (derogada), judicial annulment flag, list of subjects (materias), links to the PDF and HTML versions, a snippet of the opening text, character count of the full text, and optionally an AI-generated summary in Spanish (resumen_ia) explaining what the item is, who it affects, what it establishes, and its deadlines. A cache flag indicates if the response was served from cache.
