What Protoface does
Gives developers one API to generate video, image, audio and 3D media, and to add realtime avatars, billed by usage.
Protoface is an inference platform for generative media models. Developers reach many video, image, audio and 3D models through a single API, and the vendor says it keeps rates low through its own optimized inference stack.
The API is pay as you go, so no subscription is needed to call it. Credits are simple: 1 credit = 1 cent. You can start free without a credit card, though videos made with free credits on accounts that have never paid are watermarked and meant for evaluation only.
Two optional plans exist. Studio Unlimited, from $29/mo, covers unlimited video generation in Protoface Studio on select models. Realtime, from $20/mo, is meant for adding live avatars to an AI product. The pricing page shows these only as 'from' prices and no yearly-billed price.
Other pieces include a web dashboard for testing API calls and tracking usage, a playground, and managed inference so you do not handle GPUs or scaling. For realtime avatars, integration pages list LiveKit, Pipecat, Vapi, OpenAI Realtime, ElevenLabs Agents, Agora, VideoSDK, Python and Node.js. Enterprise customers are offered higher concurrency and priority support. The vendor positions the product for AI developers who build generative media or realtime avatars into their own products.

Pros and cons
Pros
- Pay-as-you-go API with no subscription needed
- Free start without a credit card
- One API covers video, image, audio and 3D models
- Simple credit math: 1 credit = 1 cent
Cons
- Videos from free credits are watermarked and evaluation-only
- Unlimited video plan covers only select models
- Plan prices are shown only as 'from' amounts, with no yearly price
- Realtime avatars and unlimited video need a paid plan
- Mainly built for developers, not a general end-user app
Our take
Protoface looks aimed at developers who want to call many generative media models through one API and pay only for usage. It is less suited to people who want a finished consumer app, since the offering centers on an API, a dashboard and a Studio. Unlimited video covers only select models, and plan pricing is shown just as 'from' amounts. Free-credit videos carry watermarks, so judge output quality only after a paid top-up.
