**APIs profiled:** 4

Smallest AI builds ultra-low-latency voice infrastructure - the Waves text-to-speech engine (Lightning / Lightning v2 models) for realtime speech synthesis and instant voice cloning, plus the Atoms platform for building and deploying production voice agents. The Waves REST API at https://waves-api.smallest.ai/api/v1 generates speech with sub-100ms latency, supports SSE and WebSocket streaming, and exposes voice listing and cloning via a Bearer-authenticated interface.
