# Page Weight Observations — String Normalisation + Secondary-Measure Weighted Mean

> Page Weight Observations — String Normalisation + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Runs string normalisation and secondary-measure weighted mean analysis on supplied page weight observation records (page_kb, resource_count) 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-string-normalisation-secondary-measure-df1c6971 -d '<json body>'
```

Example prompt: Can you run string normalisation and a secondary-measure weighted mean on these page weight records — I have 4 rows with site groups group-a and group-b, dates from 2026-10-01 to 2026-10-04, page_kb values of 10, 20, 15, and 30, resource counts of 1, 2, 3, and 4, and I want to analyse the page_kb field?

## When to prefer this

Choose this endpoint when you have tabular page weight observation data (page_kb and resource_count per site group and date) and need both string normalisation and a secondary-measure weighted mean in a single call at low cost ($0.01 for up to 200 rows). It is a good fit for offline, batch-style analytical passes on already-collected web performance data where no live lookup or external prediction is needed.

## Known failure modes

- Rows array empty or missing — validation error
- More than 200 rows submitted — rejected with item limit error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- page_kb or resource_count out of allowed numeric range — validation error
- Field enum value not 'page_kb' or 'resource_count' — schema rejection
- row_id exceeds 80-character max length — validation error

## How this service works

Page weight observations — String normalisation + Secondary-measure weighted mean: String normalisation + Secondary-measure weighted mean 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 independent analytical reports: (1) string-normalised representations of the supplied page weight records, and (2) a secondary-measure weighted mean computed over the selected field (page_kb or resource_count), both derived entirely from the supplied data with no external lookups.
