# Facilities Usage Numeric Row Ordering + Secondary-Measure Weighted Mean

> Facilities Usage Numeric Row Ordering + 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).

Ranks facilities usage rows numerically by occupied_seats or available_seats and computes a secondary-measure weighted mean across up to 200 supplied records, delivering two analytical reports in one call.

## 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 facilities-usage-numeric-row-ordering-secondary-measure-weighted-mean-5a04d0cc -d '<json body>'
```

Example prompt: I have up to 200 daily facilities usage records with occupied_seats and available_seats per team group — can you rank them numerically by occupied_seats and compute a weighted mean using available_seats as the secondary measure?

## When to prefer this

Choose this endpoint when you need both a ranked ordering of facilities usage rows AND a weighted mean computation in a single paid call, without requiring external data lookups or predictions. Ideal for operations teams analyzing seat utilization across up to 200 date-stamped records by team group.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, date, occupied_seats, available_seats) cause validation errors
- Invalid date format (must match YYYY-MM-DD pattern) triggers schema rejection
- Null values in numeric fields may affect weighted mean accuracy
- Invalid field enum value (anything other than occupied_seats or available_seats) causes error

## How this service works

Facilities usage — Numeric row ordering + Secondary-measure weighted mean: Numeric row ordering + Secondary-measure weighted mean for supplied facilities usage records (occupied_seats, available_seats). 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: (1) the input rows ranked in numeric order by the selected field (occupied_seats or available_seats), and (2) a weighted mean computation using the secondary measure across the supplied records, covering up to 200 rows total.
