# Reserve a chunked upload

`POST /api/uploads/`

## Request

- Base URL: `https://api.overmindlab.ai`
- URL: `https://api.overmindlab.ai/api/uploads/`

  - HTTP bearer
  - API key in header `X-Api-Key`
  - API key in cookie `sessionid`
  - API key in header `X-Api-Key`
  - HTTP bearer

Parsers must stay declared on the class: ``@action`` initkwargs only apply
through the router, so an action-level parser silently reverts elsewhere.

## Request body

  - `filename` string, required

## Response `201`

- UploadReserved
  - `upload_id` string, required
  - `filename` string, required
  - `chunk_bytes` integer, required
