What teams actually run.

Three patterns teams run with AltText.ai on day one. Each one is a plain-English prompt — no canvas, no glue code — and you can remix them into anything.

Multi-provider routing

│ Persona decides which model fits

│ Calls this provider when its strengths apply

└ Falls back to alternatives on rate-limits

Specialised pipeline

│ Use this provider for one stage

│ Pipe to a different model for the next

└ Combine outputs in the response

10 tools available

The AltText.ai toolbox.

Every AltText.ai capability your agents can call, each with a typed schema the planner reads. The router picks the right tool per step; the verifier checks the result.

Bulk Create Images

Tool to bulk upload and process a CSV file of image URLs for alt text generation. Use when you need to process multiple images at once (up to 100,000 URLs). Invalid rows are returned in row_errors for debugging.

Create Image

Tool to add an image and generate alt text. Supports both URL and base64-encoded file upload. Use when you need to generate alt text for images, with options for custom prompts, keywords, multiple languages, and ecommerce data. Rate limited to 4 calls per second.

Delete Image by Asset ID

Tool to delete an image from your library by its asset ID. Use when you need to remove a specific image permanently from your AltText.ai account.

Get Account

Tool to retrieve account settings and usage information. Use when you need to check your AltText.ai account configuration and usage limits before generating alt text.

Get Image by Asset ID

Tool to retrieve detailed information about a specific image using its asset ID. Use when you need to fetch alt text, metadata, or status of a previously processed image.

Get Images

Tool to retrieve a paginated list of images in your library, including their alt text and metadata. Use when you need to browse or filter images programmatically after authentication.

Scrape Page for Images

Tool to scrape a web page or HTML document and queue all images for alt text generation. Images are processed asynchronously. Does not execute JavaScript. Use when you need to batch-process images from a website or HTML content.

Search Images

Search for images in your AltText.ai library by keywords. Searches through your previously processed images to find matches based on URLs, alt text content, and metadata. Useful for finding specific images in large libraries. Returns paginated results with alt text and metadata. Note: This searches your own image library, not a public image database. Images must be added via the Create Image endpoint before they can be searched.

Update Account

Tool to update account settings (e.g., webhook_url, name). Use after confirming current account details to modify settings.

Update Image by Asset ID

Tool to update an image with new data including asset ID, alt text, and metadata. Use when you need to modify existing image information. Note: You cannot update the URL of an existing image.
