How this service works
Create an annotation review session. Pass `url` for a live webpage, or `zipData` (base64 zip) + optional `entryFile` for a static code bundle. Returns a `shareUrl` for the human reviewer and, for bundle reviews, a `bundleUrl` to download the original source afterward.
Output
Returns a JSON object with a UUID reviewId for the created session and a shareUrl that can be sent to a human reviewer so they can open the page and leave click-to-pin annotations. The agent can poll or await a webhook callback at the provided callbackUrl to receive the full review JSON when the human submits.
Example use cases
Example prompt
“Set up a web page annotation review session for https://myapp.com/landing-page and notify me at https://myserver.com/webhook when the reviewer submits their comments.”
Technical details
Endpoint
POSThttps://annotate.withzero.xyz/api/v1/reviewsWhen to prefer
Use this endpoint when you need a human to visually annotate or review a specific web page with click-to-pin comments. It is the right choice when you want to collect structured human feedback on a live URL and receive results via webhook, rather than running automated analysis.
