How much does the Text to Video API cost?

Each model has its own rate, shown in the table above and on the pricing page. The lowest listed rates right now are $0.007/sec (SeeDance 1.5 Pro) and $0.075 per video (Veo 3.1). You pay per generation from a prepaid balance: no subscription, no monthly minimum, and the balance does not expire. Failed generations are not charged, and a request with dry_run set to true returns the exact price without running the job.

How do I call these text to video models from code?

Send POST https://api.unifically.com/v1/tasks with your API key, a model ID (for example google/veo-3.1-fast) and an input object. The response holds a task_id: poll GET /v1/tasks/{task_id} until the status is completed, or pass a callback_url to receive the result by webhook. The request shape is the same for every model; only the model ID and the input fields change.

Can the same API turn an image into a video?

Yes. Every model on this page also accepts a start image; the full image to video list is on the Image to Video API page. The image goes in the model's input as a URL, for example start_image_url for Veo 3.1.

Can I try the text to video models before topping up?

Yes. A new UnificAlly account starts with a $0.50 signup balance, and every model page has a browser playground that runs on it, so you can compare outputs before writing any code.

How to call the Text to Video API

Every model takes the same request: a model ID and an input object. This example uses google/veo-3.1-fast; swap in any model ID from the table and the input fields from its model page.

# 1. Start a task
curl -X POST https://api.unifically.com/v1/tasks \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "google/veo-3.1-fast",
    "input": {
      "prompt": "A cinematic shot of a cat walking through a garden",
      "aspect_ratio": "16:9",
      "duration": 4,
      "resolution": "1080p"
    }
  }'

# 2. Read the result with the task_id from step 1
curl https://api.unifically.com/v1/tasks/TASK_ID \
  -H "Authorization: Bearer YOUR_API_KEY"
