How this service works
M2M Trust deterministic analysis tool: Deterministic flat-JSON dataset audit for missingness, invalid values, duplicates, cardinality and numeric ranges.
Output
A structured JSON report detailing: missingness counts and percentages per field, invalid value instances, duplicate record counts, cardinality statistics per column, and numeric range violations — all computed deterministically with no probabilistic inference.
Example use cases
Example prompt
“Run a full data quality audit on this flat JSON dataset and tell me about any missing values, duplicate rows, invalid entries, cardinality issues, and numeric fields that fall outside expected ranges.”
Technical details
Endpoint
POSThttps://energybilltoolkit.co.uk/m2m-trust/api/tools/data-quality-auditWhen to prefer
Use this endpoint when you need deterministic, reproducible data quality checks on a flat JSON dataset — specifically when you need missingness, duplicate, cardinality, and range analysis in a single call. Prefer this over probabilistic or ML-based validators when audit reproducibility and exact counts matter, such as in compliance pipelines or before loading data into a database.
Side effects
- Non-flat (nested) JSON structure returns schema validation error
- Empty dataset returns trivial audit with zero counts
- Malformed JSON returns parse error
- Extremely large dataset may exceed payload limits
- Non-numeric fields passed as numeric columns return type mismatch error
