Step by step

How to get a Wan 3.0 API key

  1. 1

    Create an account

    Sign up with Google or a magic link sent to your email. No sales call and no waitlist.

  2. 2

    Add credits

    Credits are prepaid in US dollars, from $10 by card. $10 covers about 138 2-second 480p clips with Wan 3.0 ($0.072 each). Turn on auto top-up if you don't want jobs to stop.

  3. 3

    Create the key

    Open Dashboard → API keys, name the key (e.g. “wan-prod”) and copy it. Keys start with cg_live_, and the full key is shown only once.

  4. 4

    Store it as an environment variable

    Put it in CHEAPERGEN_API_KEY on your server or in your secrets manager — never in a browser bundle, mobile app or public repository.

  5. 5

    Call Wan 3.0

    Send the request below. It costs $0.36 (28% below the official $0.50) and returns a generation id you can poll or receive by webhook.

Your first Wan 3.0 request

curl -X POST https://cheapergen.com/api/v1/run/alibaba/wan-3.0/text-to-video \
  -H "Authorization: Bearer $CHEAPERGEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "prompt": "A street-food vendor in Bangkok flips noodles in a flaming wok, night market bokeh, handheld",
  "aspect_ratio": "16:9",
  "resolution": "720p",
  "duration": 5
}'

Security

Keep your key safe

Anyone with the key can spend your balance. Details in the authentication docs.

Server-side only

Call the API from your backend. Never ship a key in a browser bundle, mobile app or public repository.

One key per app

Separate keys for production, staging and each integration let you revoke one without touching the others.

Rotate without downtime

Create a new key, deploy it, then revoke the old one. Revocation takes effect immediately.

Watch last-used times

The dashboard shows when each key was last used, so unused or unexpected keys stand out.

FAQ

Wan 3.0 API key questions

Creating a key is free, but generations are paid: there is no free tier. You add prepaid credits from $10, failed generations are refunded automatically, and the quote endpoint (POST /v1/quote/{endpoint}) prices any request for free before you run it. Wan 3.0 starts at $0.0362/s.

The key itself costs nothing. You pay per second of generated video: Wan 3.0 costs $0.0362/s at 480p, 28% below Alibaba's official $0.05/s. There is no subscription or monthly fee.

Yes. One Cheaper Gen. key works for all 41 models from 12 developers in the catalog — change the endpoint, keep the key and the balance.

The full key is shown once, when you create it. The dashboard keeps its name, prefix and last-used time; if you lose the key, create a new one and revoke the old one.

Revoke it in Dashboard → API keys — revocation takes effect immediately — then create a new key and deploy it. Use one key per app or environment so you can revoke one without touching the others.
