## Types

### LocationAvailability

How many EVSEs of one location can be used right now.

- `location_id` (string, required)
- `cpo_id` (string, required)
- `status` (LocationAvailabilityStatus, required)
- `available_evses` (integer, required)
- `total_evses` (integer, required)

### EmspPageInfo

Spirii cursor page. Pass end_cursor as the next after value.

- `has_next` (boolean, required)
- `end_cursor` (string, optional, nullable)

### ValidationError

Why one field is invalid.

- `loc` (list of ValidationErrorLocItems, required) — Where the field is: ``body`` / ``query`` / ``path`` / ``header``, then its name.
- `msg` (string, required) — What is wrong, in English.
