# List manufacturer models

> Discover supported models for a manufacturer.

## Behavior

Replace `{make}` with a supported manufacturer and URL-encode spaces or Chinese characters. The response includes `make` and `models`. An unknown manufacturer returns `404`. This is an authenticated data request and consumes quota.

**Authentication:** Secret API key in `X-API-Key`. **Quota:** One successful call consumes one data request.

## Request example

```bash theme={"system"}
curl --fail-with-body "https://api.xapichina.com/v1/makes/BMW/models?lang=en" \
  -H "X-API-Key: $XAPICHINA_API_KEY"
```

## Illustrative response

The following example is abbreviated. It demonstrates the response shape rather than live inventory or guaranteed field coverage. The generated schema describes the complete contract.

```json theme={"system"}
{
  "make": "BMW",
  "models": [
    "3 Series"
  ]
}
```

Read the [integration guide](/makes-and-models) for parameter rules, source interpretation, and error handling. Use the generated request playground with your own server-side API key.
