Bring coloring pages into the things you make

Generate from a text idea

Create a page for today's lesson, a customer's request, or the next theme in your publishing calendar. Send a prompt and poll for the finished image.

Personalize with a photo

Turn a pet portrait or family photo into a coloring page for a gift or personalized product. Your app sends a photo URL and gets an image back when it is ready.

Convert a batch of photos

Process up to 50 photo URLs in one request. Get a ZIP of individual PDFs by email, or use a signed webhook to bring the download into your workflow.

One request starts the page

Choose a style and quality, submit the job, then check its status. Completed pages are saved in the key owner's library.

API jobs use your existing credits

Business includes API access after approval. Completed jobs spend credits from the account that owns the key, just like work you create in the app. There is no separate API credit allowance.

Before you connect

How do I get API access?

Sign in and request access from your API settings. Business customers can submit a request for approval. On a lower plan, you will be prompted to upgrade to Business first. Once approved, you can create and manage API keys.

How are API jobs billed?

Completed API jobs use credits from the account that owns the key. Credit usage depends on the operation and quality. Your API jobs share your account balance with jobs you create in the app.

What files do I get back?

Individual prompt and photo jobs return a signed image URL after processing. Bulk photo jobs deliver a ZIP of individual PDFs by email, with an optional webhook for your integration. Finished pages are also saved in your ColorBliss library.

Can I sell the pages I make?

Business includes a commercial use license for coloring pages, books, and printables. You can use the API to make pages for your products or client work.
