Built by Metorial, the integration platform for agentic AI.
Generate AI-powered alternative text for an image. Provide an image via URL or base64-encoded data and receive descriptive alt text optimized for accessibility and SEO. Supports 130+ languages, custom SEO keywords, e-commerce product context, configurable writing styles, and optional ChatGPT post-processing.
Retrieve account information including plan details, credit usage, and billing period. Useful for checking remaining credits before processing images.
Search the image library by exact asset ID, URL substring, or alt text. HTTP and HTTPS queries search source URLs; other queries first try an exact asset ID, then fall back to alt-text search.
Retrieve a paginated list of images from your AltText.ai library. Each image includes its alt text, language, and metadata. Use this to browse or audit processed images.
Retrieve a previously processed image and its generated alt text by asset ID. Returns the full image record including alt text, language, keywords, and processing status.
Submit a CSV of image URLs for batch alt text generation. Returns upload acceptance, processed row count, and per-row errors; final alt text is generated separately.
Edit stored alt text, rename an image asset ID, or replace its custom metadata. The source image URL cannot be changed.
Delete an image record and its stored alt text from the image library. Returns the deleted image record.
Find image elements in a page URL or raw HTML and queue them for background alt text generation. Returns scrape and queue results, not the final alt text.
