Output Images
Most API endpoints return an OutputImageUrl — an annotated version of the input image with AI analysis results visually overlaid.
How It Works​
- You submit a dental image URL via the API
- Annie Insights AI processes and annotates the image
- The API returns a time-limited Azure Blob SAS URL to download the annotated result
SAS URL Behavior​
| Property | Value |
|---|---|
| Storage | Azure Blob Storage |
| URL validity | 72 hours (production), 24 hours (sandbox) |
| Auto-deletion | Output images are deleted after 3 days |
| Access | Read-only (sp=r) |
Time-Limited Access
Download or cache the output image immediately after receiving the API response. The SAS URL expires and the image is permanently deleted after 3 days.
Example URL​
https://annieapistorage.blob.core.windows.net/api-output-images/clinical-images/a1b2c3d4.jpg?se=2026-05-27&sp=r&sv=2021-08-06&sr=b&sig=...
Best Practices​
- Download immediately — Don't rely on the URL being available later
- Store locally — Save output images in your own storage system
- Cache results — Store the full API response JSON alongside the image
- Handle expiry — If a URL has expired, re-submit the original image for re-analysis
