Turn a prompt into a hosted clip, billed by the second
Text-to-video and image-to-video across every major video model through one endpoint. Billed per second of output in USDC, quoted before generation starts.
The call
One endpoint, priced in dollars before it runs and settled in USDC. No API key and no account — the request pays for itself.
POST /api/v1/videos/generations
Host: blockrun.aiWhat it costs
Why per call
No seat, no minimum, no contract per vendor. Each request is quoted in dollars before it runs and settles on-chain, so an agent can pay for its own work without a human holding a credit card. How the payment works →
Questions
Text-to-video or image-to-video?
Both. Every model on the rate card below accepts an image input as well as a prompt.
How is a clip priced?
Per second of generated video at the resolution you request, quoted in dollars before the job starts.
How do I get the finished clip?
Generation is asynchronous: the call returns a job you poll, and the finished clip is served from a hosted URL.
How long can a clip be?
It depends on the model — each row on the rate card links to that model's page with its duration ceiling.
