# Languages

Turn language codes into labels your humans can understand.

Paid API live · this page does not check availability. Approval describes permitted release scope; it does not mean this collection is serving.

## When to choose it

A content agent labels a language code clearly when preparing multilingual content for review.

## Dataset facts

Source: Unicode CLDR · English labels (`unicode-cldr`)

Identifier: CLDR language code

Coverage: English display labels; no translation or language detection.

Freshness: Pinned CLDR 48.0.0 edition; no live release freshness is claimed.

Limitations: A language label does not identify or translate the language of a document.

Access: Paid data operation after live availability and price checks. Discovery is free.

Usage terms: Unicode-3.0 permits redistribution with attribution. Preserve the complete Unicode License V3 notice published at the API attribution endpoint.

Reference domain: `cldr-languages-en`

## Approved source fields

- Language code
- English display name

Source fields describe the collection; use the API schema for response structure. No record counts or ingestion timestamps are asserted here.

## Query capabilities

- Exact language codes
- Case-insensitive substring query against code or English label
- Validity selection
- Cursor pagination, 1–500 values per page

## Reference request shape

Illustrative arguments for `get_reference_data`, not an executed request or a sample result. Check live availability and authorize the quoted spend before calling.

```
{
  "domain": "cldr-languages-en",
  "codes": [
    "en"
  ],
  "include_inactive": true,
  "limit": 1
}
```

`include_inactive: true` intentionally includes values whose validity is unknown. Preserve `active: null` and `reference_value_validity_unknown`; do not relabel them as known active. Use `include_inactive: false` if your task accepts only known-active values.

## Before accepting a result

Inspect the response’s source licenses, public-use terms, version, warnings and available source timestamps. An absent retrieval timestamp is unknown freshness, not today’s data.
