How this service works
Numeric precision comparisons — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied numeric precision comparisons records (source_value, transformed_value). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.
Output
Returns two independent analytical reports: (1) an equal-width histogram showing bin edges and counts for the selected field across up to 200 rows, and (2) a two-measure correlation report quantifying the linear relationship between source_value and transformed_value. No external data is fetched; all computation is performed locally on the supplied rows.
Example use cases
ETL pipeline numeric drift check
“I just ran a normalisation step on my sales figures and want to know if the transformed values still correlate tightly with the originals — can you run a histogram (5 bins) and correlation report on these 120 source/transformed pairs so I can see the distribution shift?”
Data quality audit for finance team
“Our finance team needs a statistical sanity check on a currency-conversion output: please compute an equal-width histogram with 8 bins and the two-measure correlation between the original USD amounts and the converted EUR values for the 80 rows I'm supplying.”
ML feature engineering validation
“Before I train my model, I want to confirm that my log-transform of the 'revenue' column didn't distort the distribution too badly — run a 10-bin equal-width histogram and correlation analysis on the raw vs log-transformed values for my 200 training rows.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-20-171?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, offline statistical analysis of paired numeric columns — specifically a distribution histogram plus a correlation coefficient — without any external data lookup or prediction. It is ideal for validating data transformations, auditing ETL outputs, or doing a quick quality check on numeric precision, especially when you have up to 200 pre-assembled rows and need both reports in a single $0.01 call.
Side effects
- More than 200 rows submitted — request rejected or truncated
- Missing required row fields (row_id, source_value, transformed_value) — validation error
- bins parameter outside 1–30 range — rejected
- Non-numeric or null values in source_value/transformed_value may reduce effective sample size
- Invalid date format (not YYYY-MM-DD) — schema validation failure
