# Page Weight Observations — Numeric Row Ordering + Keyed Dataset Comparison

> Page Weight Observations — Numeric Row Ordering + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Ranks page weight observation rows numerically and compares two keyed datasets across page_kb and resource_count fields, returning 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-weight-observations-numeric-row-ordering-keyed-dataset-comparison-a5650a40 -d '<json body>'
```

Example prompt: Rank my page weight observations by page_kb and compare them against a second dataset — I have two groups, group-a and group-b, with dates from 2026-10-01 through 2026-10-04 and page sizes ranging from 10 to 30 KB. Give me the numeric row ordering and keyed comparison reports.

## When to prefer this

Choose this endpoint when you have page weight observation data (page sizes in KB and resource counts per page/site) and need both a numeric ranking of rows and a keyed side-by-side comparison of two datasets in a single call. It is purpose-built for web performance data structured with site_group, date, page_kb, and resource_count fields. Prefer it over generic stats endpoints when you specifically need row ordering plus cross-dataset diff in one request at minimal cost.

## Known failure modes

- Fewer than 1 row supplied — validation error
- More than 200 rows submitted — request rejected
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Missing required fields (row_id, site_group, date, page_kb, resource_count) — rejected
- Invalid field enum value — must be page_kb or resource_count
- Mismatched row_ids between rows and other arrays may reduce keyed comparison coverage
- Null numeric values in page_kb or resource_count may affect ordering results

## How this service works

Page weight observations — Numeric row ordering + Keyed dataset comparison: Numeric row ordering + Keyed dataset comparison for supplied page weight observations records (page_kb, resource_count). 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 analytical reports: (1) a numeric row ordering of the supplied page weight observation rows ranked by the chosen field (page_kb or resource_count), and (2) a keyed dataset comparison between the primary rows array and the secondary other array, highlighting differences per shared row_id keys. No external data is fetched; analysis is performed on the submitted records only.
