LemonSlice
Interactive video avatar API that streams video back from your audio
LemonSlice turns any image into a real-time interactive avatar for voice agents and chatbots. You send audio, it streams video back.
It animates photorealistic humans, cartoons and non-human characters from a single photo with no training or rigging. The API is bring-your-own-model: any LLM, STT and TTS provider can sit behind it, with plugins for Pipecat, LiveKit and Agora, or a hosted widget that drops in with two lines of code. The vendor reports 471ms p99 latency and support for 70+ languages.
Plans start at $8 per month including 41 minutes, billed at $0.164 per included minute and $0.22 on overage. Enterprise adds 1000+ concurrency, zero data retention and EU or US data residency. A free preview lets you chat with featured avatars, but creating your own avatars and API access both require a paid plan.
