Get detailed information for a cell measurement

Retrieves detailed information for a specific cell measurement by measurement ID.

Deprecated: prefer the individual endpoints GET /steps, GET /cycles, GET /time_series, and GET /steps_and_cycles instead.

Supports zoom-based resampling: specify x_min, x_max, and x_column to fetch higher resolution data for a specific x-axis range.

Show child attributes

protocol · Protocol · object

Protocol information. Typical keys: 'name' (str), 'ambient_temperature_degc' (float), 'definition' (dict | str — a UCP protocol definition or another protocol format).

start_time · string<date-time> | null

ISO 8601 datetime with timezone (UTC preferred) marking when the test started.

test_setup · Test Setup · object

Physical test setup. Typical keys: 'cycler' (model), 'operator', 'lab', 'channel_number' (int).

step_labels_validated · boolean · default: false

Set to true only once step-type labels (Rest, CC charge, CV, discharge, etc.) have been manually reviewed. Server-inferred labels should leave this false.

notes · string | null

Free-text notes about the cell measurement

measurement_type · enum<string> · default: time_series

What shape of data this measurement holds. Determines which fields are populated and which upload flow applies. See the class docstring.

Available options: time_series, file, properties

properties · Properties · object

Flat key/value measurements, populated only when measurement_type is 'properties'. Numeric values use the Quantity format. Example: {'thickness': {'value': 0.52, 'unit': 'mm'}, 'DCIR': {'value': 12, 'unit': 'mohm'}}.

file_metadata · File Metadata · object

Metadata about uploaded files (MIME types, dimensions, etc.)

organization_id · string | null

Organization this measurement belongs to.

created_by · string | null

User ID of the user who created this measurement

created_by_email · string | null

Email of the user who created this measurement
