# Page Extraction Coverage — String Normalisation + Exact Row Deduplication

> Page Extraction Coverage — String Normalisation + Exact Row Deduplication 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).

Normalises strings and deduplicates exact rows in page extraction coverage data (extracted_fields vs expected_fields), producing two analytical reports 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 page-extraction-coverage-string-normalisation-exact-row-deduplication-43b53221 -d '<json body>'
```

Example prompt: Can you run string normalisation and exact row deduplication on my page extraction coverage data? I have rows for site groups like 'group-a' and 'group-b' with dates from 2026-10-01 to 2026-10-04, and I need both reports — extracted_fields and expected_fields are included for each row.

## When to prefer this

Choose this endpoint when you need both string normalisation and exact row deduplication applied together to page extraction coverage data in a single call, producing two independent reports. It is ideal for data quality pipelines where you want to clean and deduplicate web scraping coverage records (extracted_fields vs expected_fields) without making any external lookups or predictions, and where your dataset fits within 200 rows.

## Known failure modes

- Exceeding 200 rows in the input array returns a validation error
- Missing required fields (row_id, site_group, date, extracted_fields, expected_fields) causes rejection
- Malformed date strings not matching YYYY-MM-DD pattern cause validation failure
- Numeric field values outside the allowed range (-1e12 to 1e12) are rejected
- Empty rows array (minItems: 1 not met) returns an error

## How this service works

Page extraction coverage — String normalisation + Exact row deduplication: String normalisation + Exact row deduplication 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: one covering string normalisation results and one covering exact row deduplication results, applied to the supplied page extraction coverage records (up to 200 rows). No external lookups or predictions are made; all analysis is performed locally on the submitted data.
