# Intraday Hub to Hub Capacities

`GET /api/v2/Intraday/HubToHubCapacities/ByAreaFrom`

Returns transmission capacity changes available between two areas, no matter the path through the power grid.
It's not a border/cable capacity but rather the sum of all available paths that power could flow.
Data is available with a delay of approximately 25 minutes.

**Note**: The delivery start time must be provided in a full-hour format, such as 2025-03-01T**01:00:00**Z.
Providing the delivery start time like 2025-03-01T**01:59:59**Z results in a bad request error,
as hub to hub capacities are updated on an hourly basis and such inputs would not give meaningful responses.
 
### Response field descriptions

- **areaFrom**: the outgoing delivery area
- **areaTo**: the incoming delivery area
- **deliveryStart**: the timestamp of delivery start
- **deliveryEnd**: the timestamp of delivery end
- **capacities**: a list of capacity changes 

  Each capacity contains:
  - **outCapacity**: the available capacity out from the "from" area (areaFrom -> areaTo capacity) in MW 

  - **inCapacity**: the available capacity in to the "from" area (areaTo -> areaFrom capacity) in MW
  - **publicationTime**: the timestamp when data has been received from the capacity system
