Overview

Word Cloud API generates word cloud images from text you provide, with options for colors, fonts, shape masks, and layout. You submit a list of words with weights and receive back a PNG or JSON with word positions. It is useful for visualizing survey results, article topics, or any frequency-based text data.

💡

Common Errors & Troubleshooting

401 Unauthorized Missing or invalid API key in the request
✓ Include your API key as the api_key query parameter or in the Authorization header as specified in the docs
Empty or blank image returned Submitting too few words or all words with equal weight resulting in poor layout
✓ Provide at least 10-20 varied words; assign higher weights to important terms to improve visual hierarchy
