# Page Extraction Coverage — Record Quality Audit + String Normalisation + Date by Category Pivot

> Page Extraction Coverage — Record Quality Audit + String Normalisation + Date by Category Pivot is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-04).

Runs three analytical reports (record quality audit, string normalisation, and date-by-category pivot) on page extraction coverage data containing extracted_fields and expected_fields counts.

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-record-quality-audit-string-normalisation-e21a4a1b -d '<json body>'
```

Example prompt: Audit my page extraction coverage records — I have up to 50 rows with site_group, date, extracted_fields, and expected_fields — and give me all three reports: a record quality audit, string normalisation, and a date-by-category pivot, using extracted_fields as the target field.

## When to prefer this

Choose this endpoint when you need three simultaneous analytical passes — quality audit, string normalisation, and date pivot — on page extraction coverage data in a single cheap call. It is ideal for batch auditing scraper output quality across multiple site groups over time without needing an external analytics platform. Prefer it over single-report endpoints when you need all three report types at once and have up to 200 rows of extracted_fields/expected_fields data.

## Known failure modes

- Fewer than 1 row or more than 200 rows supplied — request rejected
- Missing required row fields (row_id, date, extracted_fields, expected_fields) — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- Numeric field values outside allowed range (±1,000,000,000,000) — rejected
- Invalid field enum value (must be 'extracted_fields' or 'expected_fields') — error response
- Payment of 0.01 USDC not provided via x402 protocol — 402 Payment Required

## How this service works

Page extraction coverage — Record quality audit + String normalisation + Date by category pivot: Record quality audit + String normalisation + Date by category pivot for supplied page extraction coverage records (extracted_fields, expected_fields). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Returns three independent analytical reports computed locally on the supplied rows: (1) a record quality audit flagging anomalies or completeness issues per row, (2) a string normalisation report standardising categorical string fields, and (3) a date-by-category pivot summarising the chosen numeric field (extracted_fields or expected_fields) grouped by date and site_group category. No external lookups are performed.
