# Page Extraction Coverage — Numeric Row Ordering + Adjacent Row Changes

> Page Extraction Coverage — Numeric Row Ordering + 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 2026-10-29).

Analyzes page extraction coverage records by computing numeric row ordering and adjacent row change reports for up to 200 rows of extracted_fields vs expected_fields data.

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 page-extraction-coverage-numeric-row-ordering-adjacent-row-changes-6801ff75 -d '<json body>'
```

Example prompt: I have page extraction records for group-a and group-b from October 2026 — can you rank them numerically by extracted_fields and show me where adjacent row values change most between rows? Here are 4 rows: row-1 (2026-10-01, group-a, expected 1, extracted 10), row-2 (2026-10-02, group-b, expected 2, extracted 20), row-3 (2026-10-03, group-a, expected 3, extracted 15), row-4 (2026-10-04, group-b, expected 4, extracted 30).

## When to prefer this

Choose this endpoint when you need quick, low-cost dual analytics (numeric ordering + adjacent row change detection) on page extraction coverage data without requiring any external data lookup, prediction, or live service — especially when you have up to 200 rows of extracted_fields vs expected_fields records across multiple site groups and dates.

## Known failure modes

- Missing required fields (row_id, date, extracted_fields, expected_fields) causes validation rejection
- Date strings not matching YYYY-MM-DD pattern are rejected
- Submitting more than 200 rows exceeds the row limit
- Null values in numeric fields may affect ordering and delta calculations
- Invalid field enum value (not 'extracted_fields' or 'expected_fields') causes error

## How this service works

Page extraction coverage — Numeric row ordering + Adjacent row changes: Numeric row ordering + Adjacent row changes for supplied page extraction coverage records (extracted_fields, expected_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

Two analytical reports for the submitted rows: (1) a numeric row ordering ranking rows by the selected field (extracted_fields or expected_fields), and (2) an adjacent row changes report showing value deltas between consecutive rows — both computed locally with no external lookups, covering up to 200 rows.
