Scored across 7 tools
Each tool targets a distinct query mode—schema, provenance, exact lookup, substring search, multi-value comparison, statistics, and top/bottom ranking. dataset_row and dataset_compare are arguably similar, but the compare tool is clearly scoped to ordered multi-value comparisons, so the overlap is manageable.
All tools share a consistent dataset_ prefix and snake_case naming, which makes them highly predictable. The suffixes mix nouns (columns, stats) and verbs (search, compare), so it is not a strict verb_noun pattern, but the convention is still coherent.
Seven tools is well-scoped for a dataset querying server. Each tool covers a distinct data exploration need without redundancy, and the count is comfortably within the ideal range.
The server covers schema discovery, provenance attribution, exact and fuzzy row retrieval, comparison queries, numeric aggregations, and ranking. For a read-only single-dataset server, there are no obvious gaps that would block normal usage.
Available Tools
7 toolsdataset_columnsDataset columns and shapeAInspect
The columns, which of them are numeric, the row count and the provenance banner of the Proofzo dataset. Call this first to learn the schema.
Inputs: no named parameters.
dataset_compareCompare rows side by sideAInspect
The rows of the Proofzo dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
Inputs: column (required), values (required).
dataset_provenanceWhere this data comes from, and how to cite itAInspect
The source, the date it was computed, the licence and the citation for the Proofzo dataset. Read this to attribute a figure correctly.
Inputs: no named parameters.
dataset_rowLook a row up by an exact keyCInspect
The rows of the Proofzo dataset where a column equals a value exactly (case-insensitive).
Inputs: value (required), column (required).
dataset_searchSearch the datasetBInspect
Rows of the Proofzo dataset whose cells contain the query (case-insensitive), up to 50.
Inputs: query (required), limit.
dataset_statsSummary statistics for a numeric columnAInspect
count, min, max, mean, median and sum of a numeric column of the Proofzo dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
Inputs: column (required).
dataset_topRank rows by a numeric columnCInspect
The highest (or lowest) rows of the Proofzo dataset by a numeric column — "which is the most/least X".
Inputs: column (required), limit, ascending.
