General

The Python “Try it” snippets attached to the Lightning v3.1 TTS and Pulse STT API reference operations used the pre-4.4.5 SDK constructor signature:

1
client = SmallestAI(token="YOUR_API_KEY")

The SDK kwarg was renamed in 4.4.5. Customers copy-pasting the old snippet hit:

TypeError: SmallestAI.__init__() got an unexpected keyword argument 'token'

All affected Python snippets in lightning-v3.1-openapi.yaml, pulse-stt-openapi.yaml, and their v4 overrides now use SmallestAI(api_key="YOUR_API_KEY"). No wire-protocol change. Existing customer code on smallestai >= 4.4.5 is unaffected.
