# Numeric Precision Comparisons — Category Frequencies & Equal-Width Histogram

> Numeric Precision Comparisons — Category Frequencies & Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Generates two local analytical reports (category frequency breakdown and equal-width histogram) for supplied numeric precision comparison records containing source and transformed values.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability numeric-precision-comparisons-category-frequencies-equal-width-86782e68 -d '<json body>'
```

Example prompt: Can you run a category frequency breakdown and a 10-bin equal-width histogram on my numeric precision comparison data? I have source_value and transformed_value pairs for up to 50 rows across two dataset groups, and I want to analyze the source_value field.

## When to prefer this

Choose this endpoint when you have a moderate dataset (up to 200 rows) of numeric source-vs-transformed value pairs and need both a categorical frequency summary and a histogram distribution report in a single API call for $0.01 USDC. Prefer this over general-purpose analytics when you specifically need equal-width binning and category frequency analysis computed locally without any external data enrichment or prediction.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Invalid bin count outside 1–30 range is rejected
- Rows missing required fields (row_id, dataset_group, date, source_value, transformed_value) fail schema validation
- Malformed date strings not matching YYYY-MM-DD pattern cause rejection
- Values outside ±1,000,000,000,000 range fail validation
- Empty rows array returns an error

## How this service works

Numeric precision comparisons — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram 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) a category frequency report showing how often values fall into each category or group, and (2) an equal-width histogram report dividing the selected numeric field (source_value or transformed_value) into the specified number of bins (1–30, default 5) with counts per bin — all computed locally without external lookups or predictions, for up to 200 supplied rows.
