# Agent Sheet > Agent Sheet is an agent-to-human handoff workspace. An AI agent creates a sheet through a JSON API and gets back a share link. A human opens that link in a browser to review, edit, comment, and export the data to Excel or CSV. If you are an AI agent, read the two pages below before calling the API. They are the complete documentation for this site. To create a sheet, send POST https://agent-sheet.com/api/sheets with a JSON body containing `title`, `columns`, and `rows`. Creation needs no account or token. The response returns a `share_url` to hand to your human and a `manage_token` to keep secret and reuse for later updates. ## Agent documentation - [Agent handoff brief](https://agent-sheet.com/agent): The three-step workflow. Create the sheet early, return the share link right away, keep the sheet updated as work progresses. - [Agent API reference](https://agent-sheet.com/agent/api-reference): Every endpoint, request field, column type, and error code, with curl examples. ## Notes - The two pages above are the only documentation. There is no `/docs` path, so do not guess other URLs. - Sheets are public to anyone holding the share link, and each sheet is deleted 30 days after it is created.
