## 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 lilambd-language-search-9b8aaf56
```

Example prompt: Can you search for endangered languages spoken in Brazil, showing up to 100 results?

## When to prefer this

Choose this endpoint when you need to query a structured database of world languages with filtering by name, family, country, or endangerment status. It is suitable for linguistic research, building language-aware applications, or exploring language diversity. Prefer this over general web search when you need structured, filterable, attributed language data in a programmatic format.

## Known failure modes

- No results returned (empty data array) when the query term doesn't match any language
- Invalid country code yields no results or an error
- Limit values outside 1-200 range may be rejected or clamped
- Payment not included results in HTTP 402 response
- Misspelled language names may return zero results

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing a 'data' array of language records matching the query, a 'count' integer indicating total matches, and an 'attribution' string citing the data source licence. Each record likely contains language name, autonym, family, country, and endangerment status.
