Developers · API v1

One API. Every model.

Images, video, audio and 3D behind one API, paid from the same balance as the studio. Create a key in Settings; the CLI is coming soon.

Same call, any output

Swap the model ID to switch between image, video and speech. The fields follow the model.

First render in three steps

  1. 1

  2. 2

    The CLI is coming soon

    The command-line tool is not published yet. Until it is, everything runs in the studio.

    npm i -g @ducklygen/cli
  3. 3

    Make your first render

    Pick a model ID from the catalog and send a prompt. Add --dry-run to see the price without spending anything.

    ducklygen run <model> -p "duck on teal waves" -o ./out/
Coming soonDucklygen CLI

Render from the terminal

Run any model from a shell, a CI job or a coding agent. Every render is priced before it starts and drawn from the same balance.

Scripts and CIEvery field of a model is a flag; a local file is uploaded for you.
JSON on stdoutOne JSON document per run, progress and errors on stderr, a non-zero exit on failure.
Coding agentsA skill file teaches your agent to check the price first and cap it.

The @ducklygen/cli package is not published yet. The commands below show how it will work.

Built for production

Authentication

A Bearer token in the Authorization header. Create keys in Settings and revoke any of them at any time.

Authorization: Bearer dk_live_...

Background renders

Starting a render answers at once with status queued. Poll the render until it has succeeded, failed or been refunded.

{ "status": "queued" }

Price first

Ask for the exact price of your inputs without starting anything. Every amount is in euro cents.

POST /v1/quote

Safe retries

Send an Idempotency-Key header and a retried request never charges twice.

Idempotency-Key: render-042

Limits

Each key has a per-minute limit and an optional daily cap. Past the limit the API answers 429.

429 Too Many Requests

Errors and refunds

JSON errors with a code and a message. A render that fails is refunded to your balance automatically.

{ "status": "refunded" }
