# Build Cache Quality Audit + Secondary-Measure Weighted Mean

> Build Cache 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 2026-10-24).

Runs a record quality audit and a weighted mean computation on supplied build cache rows (saved_seconds, cache_mb) — two analytical reports for up to 200 rows per call.

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 build-cache-quality-audit-secondary-measure-weighted-mean-e8a301b1 -d '<json body>'
```

Example prompt: Can you run a record quality audit and compute the weighted mean of saved_seconds on these build cache rows — I have about 12 rows with row_id, component, date, saved_seconds, and cache_mb fields?

## When to prefer this

Choose this endpoint when you need both a data quality audit and a weighted mean statistic on build cache metrics (saved_seconds, cache_mb) in a single low-cost call. It is ideal for CI/CD analytics pipelines where you want to validate data integrity and compute aggregate performance metrics without any external data sources or live lookups. Prefer it over general-purpose analytics tools when your dataset fits within 200 rows and you want a bundled two-report result at minimal cost.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, component, date, saved_seconds, cache_mb) cause row-level validation errors
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- All rows have null values for the selected field — weighted mean cannot be computed
- Malformed JSON payload returns 4xx error

## How this service works

Build cache — Record quality audit + Secondary-measure weighted mean: Record quality audit + Secondary-measure weighted mean for supplied build cache records (saved_seconds, cache_mb). 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) a record quality audit flagging missing, null, or anomalous values across the supplied rows, and (2) a weighted mean of the selected field (saved_seconds or cache_mb) as a secondary-measure statistic — computed entirely from the supplied data with no external lookups.
