The function of the API is basically to access the images' metadata stored in the database.
## Usage
The API exposes some endpoints to interact with the database.
### GET `/images`
Allows to get a list of image documents.
#### Query params
-`limit`: an optional parameter, which accepts a non-negative integer that dictates the number of documents that the list will have. If its value is equal to `0`, or if this parameter is missing, the endpoint will return all the image documents in the database.
-`status`: an optional parameter, which accepts the values `consumed`, `available` and `unavailable`. It filters the documents that have only the `status` attribute equal to that indicated in the parameter's value. If the parameter is missing, no filter will be applied to the document.
#### Example
-`GET /images?limit=5&status=available`: will return 5 documents that have the `available` value in their `status` attribute.
### PUT `/images/<id>`
Modifies an existing image document. The request must provide a JSON-formatted body, with one or more valid document attributes. The existing document attributes will be replaced with the provided new ones.
#### Params
-`id`: the id of the document to be modified.
#### Example
-`PUT /images/61f7e48f0c651345677b7775` with body `{ "status": "consumed" }`: will modify the document referenced by the `id` param, changing their `status` value to `consumed`.
