`POST /v1/boards/{board}/tabs/{tab}/revisions`

## TL;DR

| Question | Answer |
|---|---|
| What does it do? | Make a revision of a tab as an agent. |
| What does it take? | A JSON body of type [`AgentCreateBoardRevisionBody`](https://docs.plotwork.dev/api/schemas.md#agentcreateboardrevisionbody). |
| What does it return? | Status 201 with a body of type [`AgentBoardRevisionCreated`](https://docs.plotwork.dev/api/schemas.md#agentboardrevisioncreated). |
| What can go wrong? | `400` the body is not valid; `401` the API key is missing or not valid; `403` the account's plan does not include the REST API (plan.rest_not_included), the key is a person's own (boards.org_key_required), a trusted publisher (boards.publisher_not_allowed), an organisation key without the boards scope (key.scope_missing), boards are not on (boards.not_enabled), or the caller may look but not change the board (boards.forbidden); `404` no such board, tab or revision, or one not open to the caller (boards.revision_not_found): the cases look alike; `409` the tab has as many open revisions as it may (boards.revision_limit); `413` the body is larger than the API takes; `429` too many requests, or a daily limit is spent; `503` live whiteboards are not set up on this server. Every failure uses the one error envelope. |
