## Tools available

**10** tools available. First 10:

- `ALTTEXT_AI_CREATE_BULK_IMAGES` — 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.
- `ALTTEXT_AI_CREATE_IMAGE` — 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.
- `ALTTEXT_AI_DELETE_IMAGE_BY_ASSET_ID` — 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.
- `ALTTEXT_AI_GET_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.
- `ALTTEXT_AI_GET_IMAGE_BY_ASSET_ID` — 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.
- `ALTTEXT_AI_GET_IMAGES` — 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.
- `ALTTEXT_AI_SCRAPE_PAGE` — 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.
- `ALTTEXT_AI_SEARCH_IMAGES` — 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.
- `ALTTEXT_AI_UPDATE_ACCOUNT` — Update Account — Tool to update account settings (e.g., webhook_url, name). Use after confirming current account details to modify settings.
- `ALTTEXT_AI_UPDATE_IMAGE_BY_ASSET_ID` — 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.

## How agents use AltText.ai

Inside a Definable workflow, AltText.ai is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → AltText.ai** — the Researcher (GPT-5.5) pulls context from AltText.ai (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → AltText.ai** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into AltText.ai (create record, post message, draft email).
- **Designer / Engineer → Distributor → AltText.ai** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via AltText.ai (attach file, open PR comment, post status).

The Verifier checks every AltText.ai call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
