The Web Accessibility Analyzer API is a comprehensive tool designed to help developers, designers, and accessibility professionals identify and fix accessibility issues on websites. Built with modern web technologies, it provides automated analysis of web pages and AI-powered suggestions for improving accessibility compliance.
The API analyzes websites for three critical accessibility areas:
- Detects missing alt attributes on images
- Identifies vague or non-descriptive alt text (e.g., "image", "photo", "picture")
- Provides actionable recommendations for meaningful alt text
- Supports all image formats found in HTML
<img>tags
- Analyzes anchor tag accessibility across multiple dimensions:
- Descriptive Link Text: Identifies non-descriptive links like "click here", "read more"
- External Link Handling: Checks if external links properly use
target="_blank" - Proper Link Usage: Validates correct use of
hrefattributes - Keyboard Navigation: Ensures links are accessible via keyboard
