# Robots Review Observations — Weighted Mean & Date Pivot Analytics

> Robots Review Observations — Weighted Mean & Date Pivot Analytics 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).

Computes a secondary-measure weighted mean and a date-by-category pivot table for up to 200 rows of robots.txt review observation data (checked_paths, restricted_paths).

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 robots-review-observations-weighted-mean-date-pivot-analytics-ab21b01f -d '<json body>'
```

Example prompt: I have 4 robots review observation records — row-1 (group-a, 2026-10-01, checked_paths=10, restricted_paths=1), row-2 (group-b, 2026-10-02, checked_paths=20, restricted_paths=2), row-3 (group-a, 2026-10-03, checked_paths=15, restricted_paths=3), row-4 (group-b, 2026-10-04, checked_paths=30, restricted_paths=4) — can you compute the weighted mean of restricted_paths and also give me a pivot of dates by site group?

## When to prefer this

Choose this endpoint when you have up to 200 robots review observation records and need both a weighted mean summary of a numeric measure (checked_paths or restricted_paths) and a date-by-category pivot in a single low-cost call ($0.01 USDC). It is ideal for offline/batch analysis of crawl access data without requiring external data sources, live lookups, or ML predictions. Prefer this over general analytics services when your data fits the robots review schema and you want two complementary statistical views in one request.

## Known failure modes

- Fewer than 1 row supplied — minimum 1 row required
- More than 200 rows supplied — exceeds maximum row limit
- Invalid date format — must match YYYY-MM-DD pattern
- Missing required fields (row_id, site_group, date, checked_paths, restricted_paths) on any row
- Invalid field enum value — must be 'checked_paths' or 'restricted_paths'
- Numeric values out of allowed range (±1,000,000,000,000)
- Payment not provided or insufficient — requires 0.01 USDC via x402

## How this service works

Robots review observations — Secondary-measure weighted mean + Date by category pivot: Secondary-measure weighted mean + Date by category pivot for supplied robots review observations records (checked_paths, restricted_paths). 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 secondary-measure weighted mean calculation for the selected field (checked_paths or restricted_paths) across all supplied rows, and (2) a date-by-category pivot table grouping values by site_group and date. Both reports are computed locally from the supplied data with no external lookups.
