generate_alt_text

Generate Alt Text

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.

get_account

Get Account

Retrieve account information including plan details, credit usage, and billing period. Useful for checking remaining credits before processing images.

search_images

Search 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.

list_images

List Images

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.

get_image

Get Image

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.

bulk_generate_alt_text

Bulk Generate Alt Text

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.

update_image

Update Image

Edit stored alt text, rename an image asset ID, or replace its custom metadata. The source image URL cannot be changed.

delete_image

Delete Image

Delete an image record and its stored alt text from the image library. Returns the deleted image record.

scrape_page

Generate Alt Text for a Page

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.
