# API Contracts Record Quality Audit + Secondary-Measure Weighted Mean

> API Contracts Record Quality Audit + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Runs a record quality audit and a secondary-measure weighted mean analysis on API contract data rows containing fields_checked and incompatible_fields metrics.

## 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 api-contracts-record-quality-audit-secondary-measure-weighted-mean-b0c44e0e -d '<json body>'
```

Example prompt: Can you run a record quality audit and weighted mean on these API contract records — I have 4 rows for components group-a and group-b from 2026-10-01 to 2026-10-04, with fields_checked values of 10, 20, 15, 30 and incompatible_fields of 1, 2, 3, 4 — use fields_checked as the weighting measure.

## When to prefer this

Choose this endpoint when you have up to 200 API contract inspection records and need both a data quality audit and a weighted mean statistic in a single low-cost call. It is ideal for offline or batch analytical workflows where no live data lookup, external enrichment, or predictive output is needed — just local statistical computation over supplied rows. At $0.01 USDC for two reports, it suits lightweight QA pipelines, sprint retrospectives, or compliance checks on exported contract data.

## Known failure modes

- Missing required fields (row_id, component, date, fields_checked, or incompatible_fields) cause row-level validation errors
- More than 200 rows submitted results in rejection or truncation
- Invalid date format (not YYYY-MM-DD) causes parsing failure
- Non-numeric values in fields_checked or incompatible_fields cause computation errors
- Empty rows array returns an error
- Invalid field enum value (not fields_checked or incompatible_fields) causes report failure

## How this service works

API contracts — Record quality audit + Secondary-measure weighted mean: Record quality audit + Secondary-measure weighted mean for supplied api contracts records (fields_checked, incompatible_fields). 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 record quality audit flagging issues such as null values, out-of-range entries, or malformed dates across the supplied rows; and (2) a weighted mean calculation for the selected secondary measure (fields_checked or incompatible_fields), computed locally with no external lookups. Both reports cover up to 200 input rows.
