Search for electricity meters at a specific address.

This endpoint allows searching for meters by postcode and optionally by building identifier. For data protection and contractual reasons, meter details are returned in an encrypted format that can be used in subsequent API calls to retrieve the full meter information.

The search works in two steps:
1. Search for meters at the specified address using this endpoint
2. Call the /meter/by-ref/{meter_ref} endpoint with the returned reference to get the full meter details.

Search meters

Retrieve detailed information about a meter using its MPAN.

This endpoint allows direct lookup of meter information when the MPAN is already known.

Get meter info by MPAN

Retrieve meter information using an encrypted reference.

Get meter info by meter ref

Retrieve detailed information about a meter using its address.

This endpoint allows direct lookup of meter information by address, when the MPAN is not already known (if the MPAN is known, use the /meter/{mpan} endpoint).

Handle notification of an event happening on an asset.

This endpoint allows reporting various events related to an asset, such as:
- Plug-in/plug-out events
- Updates to charging intent
- Charge now events

If a tariff is included, it must comply with the OSM opening hours standard (https://wiki.openstreetmap.org/wiki/Key:opening_hours) for off-peak times and have a valid timezone, or a 400 error will be returned.

Handle asset event

Provide an update on the handling of a given event by a given asset.

This endpoint allows asset controllers to report back the status of event handling. The `asset_id` can be either the Axle UUID or an external ID if `asset_id_is_external` is true.

Note: This will not work for non-UUID external asset IDs.

Update event status

Send asset readings data to Axle.

This endpoint accepts compressed data using gzip encoding. Returns statuses of the processed data, indicating whether the data were accepted or rejected.
