# Validation Rule Results — Duplicate Key Report & Category Frequencies

> Validation Rule Results — Duplicate Key Report & Category Frequencies is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Analyzes validation rule result records to detect duplicate row keys and compute category-level frequencies of passed/total rules per dataset group.

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-duplicate-key-report-category-frequencies-1f6b65c7 -d '<json body>'
```

Example prompt: Check these 4 validation records for duplicate row IDs and give me a frequency breakdown by dataset group — rows are row-1 through row-4, dated 2026-10-01 to 2026-10-04, groups are group-a and group-b, with passed_rules of 10, 20, 15, 30 and total_rules of 1, 2, 3, 4.

## When to prefer this

Choose this endpoint when you need to simultaneously detect duplicate row identifiers and compute category-level frequency distributions from validation rule result records (passed_rules, total_rules). Ideal for data quality auditing pipelines where you want both key-collision detection and group-level aggregation in a single call for up to 200 records.

## Known failure modes

- Empty rows array or missing required fields (row_id, dataset_group, date, passed_rules, total_rules) causes validation error
- More than 200 rows submitted exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Numeric values outside ±1,000,000,000,000 range rejected
- Payment failure via x402 protocol blocks request

## How this service works

Validation rule results — Duplicate key report + Category frequencies: Duplicate key report + Category frequencies 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 identifying any row_ids that appear more than once across the submitted records, along with category frequency counts showing how often each dataset_group value appears and potentially summarizing passed/total rule statistics per category.
