# API Contracts — Record Quality Audit + Trailing Mean Series

> API Contracts — Record Quality Audit + Trailing Mean Series 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 two local analytical reports on API contract records: a record quality audit and a trailing mean time-series, covering fields_checked and incompatible_fields metrics for up to 200 rows.

## 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-trailing-mean-series-1163ddc6 -d '<json body>'
```

Example prompt: Can you run a record quality audit and trailing mean series on my API contract data — I have rows with fields_checked and incompatible_fields values by date and component, using a window of 3, and I want the analysis on the fields_checked field?

## When to prefer this

Choose this endpoint when you need both a data quality audit and a rolling average time-series on API contract records in a single cheap call ($0.01 USDC). It is ideal for offline/batch analysis of up to 200 contract records without requiring any live data lookups or external integrations. Prefer it over general analytics tools when your data is already structured with component, date, fields_checked, and incompatible_fields columns.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum batch limit
- Invalid date format (non-YYYY-MM-DD) causes row-level validation failure
- Window size larger than number of rows may produce sparse or empty series
- Missing required fields (row_id, fields_checked, incompatible_fields) causes schema rejection
- Numeric values outside ±1,000,000,000,000 range rejected

## How this service works

API contracts — Record quality audit + Trailing mean series: Record quality audit + Trailing mean series 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 reports: (1) a record quality audit summarizing data completeness, anomalies, and validity issues across the supplied rows, and (2) a trailing mean time series computed over the chosen field (fields_checked or incompatible_fields) using the specified window size — all processed locally with no external lookups.
