Why use Ceven?

  1. AI native AltText.ai integration

    • Describe the outcome and Ceven picks the right AltText.ai calls, fills the parameters, and checks the result.
    • Structured, agent friendly tool schemas so each call runs reliably instead of by guesswork.
    • Rich coverage for reading, writing, and querying your AltText.ai data, across all 10 of its actions.

  2. Managed auth

    • Built in OAuth with automatic token refresh and rotation.
    • One place to manage, scope, and revoke AltText.ai access.
    • Per user and per environment credentials instead of shared keys.

  3. Agent optimized design

    • Actions are tuned from real success and error rates so reliability climbs over time.
    • Full execution logs so you always know what ran in AltText.ai, when, and on whose behalf.
    • The agent pauses and asks when AltText.ai is unclear instead of plowing ahead.

  4. Enterprise grade security

    • Fine grained access so you control which agents and people can reach AltText.ai.
    • Least privilege by default, read scopes first and only the writes a workflow needs.
    • A full audit trail of every AltText.ai action to support review and sign off.

Frequently asked questions

Ceven uses a paginated approach to interact with your image library. Instead of attempting to pull every image in one request, the agent requests small batches of records. It iterates through these pages, processing each image through your defined workflow and then moving to the next set. This prevents timeout errors and ensures that no images are skipped during a bulk update. If your library contains tens of thousands of images, the agent will track its progress and can resume from the last successful page if the process is interrupted, ensuring total coverage of your site assets.
Yes. You can manage the global settings within your AltText.ai account to influence how descriptions are phrased. Ceven can trigger these updates via the Update Account action. Once you set the preferred tone or length in the account settings, all subsequent generation calls made by the agent will follow those rules. For specific images that require a different approach, you can use the Update Alt Text action to manually refine the output after the AI provides the first draft, which then stores the corrected version in the library.
AltText.ai enforces strict credit limits based on your subscription tier. If the agent hits a credit limit, the API returns a specific error code indicating insufficient balance. Ceven is designed to catch this error immediately. The agent will stop the current workflow to prevent repeated failed calls and will send you a notification stating exactly how many images were processed and that the run paused due to credit exhaustion. You can then top up your credits in the AltText.ai dashboard and tell the agent to resume from where it left off.
No. Ceven never stores your actual image files. The integration works by passing image URLs between your storage provider and the AltText.ai API. The agent only handles the text descriptions and the metadata associated with the image IDs. When the agent syncs a description to your CMS, it reads the text from AltText.ai and writes it to your destination system. This ensures that your media assets remain in your secure storage and that Ceven only acts as the orchestration layer for the descriptive text.
Yes. The agent uses the Get Images or Search Images actions to inspect the current state of your library. It can filter for images where the alt text field is empty or contains placeholder text. By comparing the AltText.ai library against your actual website source code, the agent can identify gaps where images are missing descriptions entirely. This allows you to run highly efficient workflows that only spend credits on images that actually need new descriptions rather than wasting resources on already optimized content.
You can configure a webhook URL in AltText.ai that points to a Ceven listener. When AltText.ai finishes processing an image, it sends a POST request to that URL containing the image ID and the generated text. The Ceven agent detects this incoming event and immediately triggers the next step in your workflow, such as updating a product page in your store. This creates a real time loop where images are tagged and published almost instantly after upload, removing the need for the agent to constantly poll the API for updates.
While AltText.ai allows for bulk processing, there are API rate limits on how many requests can be sent per second. If the agent detects a rate limit error, it automatically implements a back off strategy. This means the agent will pause for a few seconds and then retry the request at a slower pace. This ensures that your account does not get flagged for abuse and that every image is processed successfully. For extremely large libraries, we recommend scheduling the agent to run during low traffic hours to ensure maximum stability.
The ability to generate alt text in different languages depends on the current capabilities of the AltText.ai engine. Ceven passes the request to the API and returns whatever language the service provides. If you have account settings configured for a specific language, the agent will receive descriptions in that language. If you need to translate those descriptions into multiple languages for a global site, you can add a translation step in your Ceven workflow immediately after the AltText.ai generation step to ensure every regional site is accessible.
