Capabilities

Tools

7 tools
dataset_columns
Dataset columns and shape
The columns, which of them are numeric, the row count and the provenance banner of the ProbeLedger dataset. Call this first to learn the schema.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
dataset_compare
Compare rows side by side
The rows of the ProbeLedger dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column', 'values'], 'properties': {'column': {'type': 'string', 'minLength': 1}, 'values': {'type': 'array', 'items': {'type': 'string', 'minLength': 1}, 'maxItems': 10, 'minItems': 2}}, 'additionalProperties': False}
dataset_provenance
Where this data comes from, and how to cite it
The source, the date it was computed, the licence and the citation for the ProbeLedger dataset. Read this to attribute a figure correctly.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
dataset_row
Look a row up by an exact key
The rows of the ProbeLedger dataset where a column equals a value exactly (case-insensitive).
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column', 'value'], 'properties': {'value': {'type': 'string', 'minLength': 1}, 'column': {'type': 'string', 'minLength': 1}}, 'additionalProperties': False}
dataset_search
Search the dataset
Rows of the ProbeLedger dataset whose cells contain the query (case-insensitive), up to 50.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['query'], 'properties': {'limit': {'type': 'integer', 'maximum': 50, 'minimum': 1}, 'query': {'type': 'string', 'minLength': 1, 'description': 'text to look for in any cell'}}, 'additionalProperties': False}
dataset_stats
Summary statistics for a numeric column
count, min, max, mean, median and sum of a numeric column of the ProbeLedger dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column'], 'properties': {'column': {'type': 'string', 'minLength': 1}}, 'additionalProperties': False}
dataset_top
Rank rows by a numeric column
The highest (or lowest) rows of the ProbeLedger dataset by a numeric column — "which is the most/least X".
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column'], 'properties': {'limit': {'type': 'integer', 'maximum': 50, 'minimum': 1}, 'column': {'type': 'string', 'minLength': 1}, 'ascending': {'type': 'boolean', 'description': 'true for the lowest first; default highest first'}}, 'additionalProperties': False}
