Filter since v2.0.0

# fswa\_ai\_transport

Overrides the LLM transport the Build with AI agent talks through, bypassing built-in provider resolution.

/ Signature

```
apply_filters( 'fswa_ai_transport', $transport )
```

/ When it fires

Fires first in transport resolution, before the WordPress AI Client and stored provider keys are considered. Useful for routing the agent through a proxy or a custom backend without storing keys in WordPress.

/ Parameters

| Name | In | Type | Req | Description |
| --- | --- | --- | --- | --- |
| $transport | param | LlmTransportInterface|null | yes | Transport override. Default \`null\` (built-in resolution runs). |

/ Returns

`LlmTransportInterface|null` An object implementing \`LlmTransportInterface\` to route all agent LLM calls through it, or \`null\` to fall back to the WordPress AI Client / bring-your-own-key providers.

/ Examples

Route agent calls through a custom transport

```
add_filter( 'fswa_ai_transport', function ( $transport ) {
    return new My_Proxy_Transport(); // implements LlmTransportInterface
} );
```
