[ref-capabilities]: /docs/server-sdks/reference/python/core/capabilities

[declared-capabilities]: /docs/server-sdks/reference/python/core/capabilities/declared-capabilities

Whether the client declared `name`. A convenience over

## Parameters

**`body_params`** `Any` — required

A SWML request body, or a user variables dict.

---

**`name`** `str` — required

Capability name, such as `"display_content"`.

## Returns

`bool` -- `True` only when the capability was explicitly declared truthy.

## Example

```python {4}
from signalwire.core.capabilities import has_capability

def configure(query_params, body_params, headers, ephemeral_agent):
    if has_capability(body_params, "transcript"):
        ephemeral_agent.set_global_data({"show_transcript": True})
```

Part of the [client capabilities][ref-capabilities] module.
