# Schema Conformity — Trailing Mean Series + Adjacent Row Changes

> Schema Conformity — Trailing Mean Series + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Computes trailing moving average series and adjacent row delta changes for schema conformity metrics (valid_records, checked_records) over up to 200 supplied rows, returning two independent analytical reports.

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 schema-conformity-trailing-mean-series-adjacent-row-changes-004c256b -d '<json body>'
```

Example prompt: Analyze my schema conformity data for the valid_records field using a trailing mean window of 5 rows and also show me adjacent row changes — here are 20 rows with date, dataset_group, valid_records, and checked_records values I'll paste in.

## When to prefer this

Choose this endpoint when you need both a trailing moving-average time series and row-to-row delta analysis on schema conformity metrics (valid_records, checked_records) in a single cost-efficient call. It is ideal for offline or batch data quality analysis where no live data lookup, prediction, or external integration is needed, and when your dataset fits within 200 rows.

## Known failure modes

- Fewer than 2 rows supplied (minItems violation)
- More than 200 rows supplied (maxItems violation)
- Invalid date format not matching YYYY-MM-DD pattern
- Missing required fields: row_id, dataset_group, date, valid_records, or checked_records
- Window size outside valid range (2–200)
- Numeric values exceeding ±1,000,000,000,000
- Additional properties included in row objects (additionalProperties: false)

## How this service works

Schema conformity — Trailing mean series + Adjacent row changes: Trailing mean series + Adjacent row changes for supplied schema conformity records (valid_records, checked_records). 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 for the chosen field (valid_records or checked_records): (1) a trailing mean series showing the rolling average over the specified window for each row, and (2) adjacent row changes showing the delta between each consecutive row. Both reports cover up to 200 supplied rows and are computed locally without external lookups.
