## How to call it through Zero

```sh
zero fetch --capability okf-index-brazilian-federal-legislation-search-18caedb9
```

Example prompt: Can you look up the Brazilian federal law 10406 from 2002 — that's the Código Civil — using OKF Index and show me the details?

## When to prefer this

Choose this endpoint when you need to retrieve or search Brazilian federal legislation by law number/year or topic keywords. It is purpose-built for Brazilian federal law discovery and supports well-known aliases like LGPD, CDC, and Código Civil. Prefer this over generic web search when you need structured legislation metadata and support for pagination through results.

## Known failure modes

- Query exceeds 160 characters — truncate or shorten the search term
- Invalid law type enum value — must be one of: constituicao, leis-ordinarias, leis-complementares, leis-delegadas, decretos-lei
- Year outside 1800–2099 range — use a valid year
- No matching legislation found — returns empty result set
- Malformed cursor in 'after' parameter — do not generate cursors manually, only use values returned from previous responses
- Payment failure — $0.01 USDC required per call via x402 protocol

## How this service works

OKF Index: search Brazilian federal laws by number/year or words (up to 20 items), paid per call

## Output

Returns up to 20 matching Brazilian federal legislation items. Each item typically includes the law number, year, type (e.g. lei-ordinaria, decreto-lei), title or subject matter, and the issuing authority. A pagination cursor ('next') may be included to retrieve additional results.
