# Validation Rule Results — Duplicate Key Report & Equal-Width Histogram

> Validation Rule Results — Duplicate Key Report & 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 2026-10-14).

Analyzes validation rule result records to detect duplicate row keys and compute an equal-width histogram over passed_rules or total_rules values.

## 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-duplicate-key-report-equal-width-histogram-e167b5e0 -d '<json body>'
```

Example prompt: Can you analyze these validation rule results for duplicate row keys and give me a 10-bin equal-width histogram over the passed_rules field? I have 4 records: row-1 (group-a, 2026-10-01, passed=10, total=1), row-2 (group-b, 2026-10-02, passed=20, total=2), row-3 (group-a, 2026-10-03, passed=15, total=3), row-4 (group-b, 2026-10-04, passed=30, total=4).

## When to prefer this

Choose this endpoint when you need both duplicate key detection and a histogram in a single call over validation rule result records with the specific schema (row_id, dataset_group, date, passed_rules, total_rules). It is purpose-built for data quality audit workflows where you want to spot repeated identifiers and understand the distribution of rule compliance metrics simultaneously, without building custom analytics code.

## Known failure modes

- Empty rows array or fewer than 1 item returns a validation error
- bins value outside 1–30 range is rejected
- Rows missing required fields (row_id, dataset_group, date, passed_rules, total_rules) fail schema validation
- date strings not matching YYYY-MM-DD pattern are rejected
- Numeric values outside ±1,000,000,000,000 are rejected
- Payment failure or insufficient USDC balance returns a 402 error

## How this service works

Validation rule results — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram 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 a duplicate key report listing any row_id values that appear more than once in the input, plus an equal-width histogram partitioned into the requested number of bins over the chosen field (passed_rules or total_rules), including bin boundaries and record counts per bin. Up to 200 input rows and up to 30 bins are supported.
