How this service works
Images on a page with URL, alt text, declared size, lazy loading and format, counting images without alt text and flagging missing modern formats. For accessibility and SEO audits.
Output
Returns a JSON object containing: total image count, per-image detail array (URL, alt text, width, height, format, lazy flag, missing_alt flag), format breakdown by type (png, svg, webp, etc.), count of images missing alt text, count of images without dimensions, count of lazy-loaded images, the final resolved URL of the page, and an array of human-readable warning strings highlighting accessibility or SEO issues.
Example use cases
Accessibility compliance check for a landing page
“Check https://mycompany.com/landing for all images and tell me which ones are missing alt text — I need this for a WCAG accessibility review.”
SEO image format audit before launch
“Scan https://myblog.com for all images and flag any that are still in PNG or JPEG instead of WebP — I want to know what to convert before we go live.”
Inventory all images on a competitor page
“Pull a full list of every image on https://competitor.com/products, including their URLs, dimensions, and whether they're lazy loaded.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/page-images?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, per-image breakdown of all images on a specific webpage for accessibility audits (WCAG alt text compliance), SEO image optimization reviews (format modernization), or frontend quality checks. It is purpose-built for image-specific page audits rather than general page scraping, and returns pre-computed counts and warnings, saving downstream processing steps.
Side effects
- Invalid or unreachable URL returns an error with no image data
- Page with bot protection or CAPTCHA may return empty or partial results
- Very large pages may be truncated if limit parameter is not set
- Pages requiring authentication will not return protected image assets
- Malformed URL in input body causes validation error
