Questions.

Common questions about the Crossword Generator API.

Read the docs →
Which plan fits generating 10,000 crosswords a month?
The Starter plan easily covers this volume. At 4 credits per call, 10,000 crosswords require 40,000 credits, leaving plenty of room within Starter's 200,000 monthly credits. That works out to about $0.60 per 1,000 crosswords. The Free plan gives you 50 crosswords per month for testing.
Are puzzle image downloads and HTML exports included on the Free plan?
No, rendered HTML grids and downloadable puzzle and solution PNG images are premium features reserved for paid plans. The Free plan returns raw puzzle data, giving you the full 2D grid layout along with all across and down clue lists, answers, and word lengths.
What themes and grid sizes are supported?
You can generate puzzles in small, medium, or large grid sizes. Built-in themes include animals, food, sports, science, geography, or a random selection across categories.
Can I adjust the difficulty of generated crosswords?
Yes, you can set the difficulty parameter to easy, medium, or hard. Crossword Generator adapts the word selection and grid layout to suit the requested challenge level.
Can I link to the crossword and solution images permanently?
No. On paid plans, the image and solution image objects include an expiration timestamp alongside the download URL. If you plan to serve or publish these PNG files later, download them to your own storage before the link expires.
