# Validation Rule Results Analytics — Equal-Width Histogram & Missing-Value Fill

> Validation Rule Results Analytics — Equal-Width Histogram & Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Generates an equal-width histogram and explicit missing-value fill report for validation rule results data (passed_rules, total_rules) across up to 200 rows.

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 validation-rule-results-analytics-equal-width-histogram-missing-value-c3b7348d -d '<json body>'
```

Example prompt: Can you run an equal-width histogram with 10 bins on the passed_rules field from my validation results dataset — using median to fill any missing values? I have about 50 rows with row_id, dataset_group, date, passed_rules, and total_rules.

## When to prefer this

Choose this endpoint when you need fast, local statistical analysis of validation rule result records — specifically equal-width histogram computation and missing-value imputation — without any external data lookups or predictions. Ideal for data quality auditing workflows where you want to understand the distribution of passed_rules or total_rules across dataset groups. Best suited for datasets of up to 200 rows where a low-cost ($0.01 USDC) dual-report output is sufficient.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — request rejected
- Invalid date format (not YYYY-MM-DD) — schema validation error
- bins value outside 1–30 range — rejected
- Missing required fields (row_id, dataset_group, date, passed_rules, total_rules) — validation error
- All values null in selected field — histogram may be degenerate or empty

## How this service works

Validation rule results — Equal-width histogram + Explicit missing-value fill: Equal-width histogram + Explicit missing-value fill for supplied validation rule results records (passed_rules, total_rules). 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 analytical reports: (1) an equal-width histogram showing the bin distribution of the selected field (passed_rules or total_rules) across submitted rows, and (2) a missing-value fill report showing how null values were replaced using the specified method (zero, mean, or median). Both reports are computed locally on the supplied data with no external lookups.
