TalkPix API

TalkPix Developer API brings talking-photo video generation directly into your code. Key features: • One POST request turns a portrait and script into a lip-synced MP4 • 30 voices across 10 languages, or upload your own audio • POST /estimate shows credit cost before you render • Poll job status or receive a signed webhook on completion • Pay per rendered second from prepaid credits with no subscription • Automatic refunds when a render fails • Code examples in curl, Node and Python, plus an npm client. The API runs the same lip-sync pipeline behind the TalkPix web app, so output matches what studio users receive. Renders are asynchronous: you start a job, receive an ID, then either poll for the result or wait for a signed webhook when the MP4 is ready. Pricing is transparent at 1 credit per second for 720p and 2 credits per second for 1080p. Credits are reserved before the provider is called and refunded automatically if a render fails. Authentication uses API keys created in your account settings, which should be stored as secrets. Because there is no subscription, you spend credits only on videos you actually produce, and the same wallet works for studio renders. Commercial use is included. Ideal for developers and product teams adding personalized talking videos to apps, e-learning platforms, marketing tools, and customer messaging services. Teams can scale video renders programmatically without managing their own video infrastructure.
