API for developers

Video through an API.
Cheaper than building it yourself.

One predictable API for video generation: current models, a price before you start, and async jobs. Wan 3 is in the catalog now — new models join the same integration.

Why Gensta API

Three reasons to use an API instead of a provider directly

We handle models, the queue, and pricing — you call one contract.

01

The best prices

Pay only for generations, no monthly plan. 720p for 5 seconds starts at $0.39. The margin stays in your product.

02

The best AI models

We start with Wan 3. The catalog will grow, and your code stays the same POST /v1/generations.

03

High reliability

Jobs do not get lost in the queue. The price is fixed before launch. A retry does not charge twice.

Catalog

Wan 3 is live. Next models use the same calls

Text, frames, references, and audio — one contract. You do not rewrite the integration when the next model arrives.

  • Text → video
  • Photo → video
  • References and edit
  • Synchronized audio

Pricing

Pay per second, not for a plan

No minimum package. The example below is text-to-video, 720p, 5 seconds.

FAQ

The short version

Details live in the docs. This is what you need before the first request.

Documentation
Which models are available?

The API currently includes Wan 3: text, image, references, edit, and extend. New models join the same contract without changing your integration.

How do I start?

Open the portal, create a project and key, then send POST /v1/generations. Read status and the video URL with a separate GET.

How do I pay?

Pay as you go from a USD balance. Top up in the developer portal — no monthly plan.

Do I need to keep the connection open?

No. Video creation is async: POST returns an ID and queued status immediately. You fetch the result with a later request.

Connect video models through one contract

Open the portal, get a key, and run the first generation.
