# Wind Observations Grouped Summary & Date-Category Pivot

> Wind Observations Grouped Summary & Date-Category Pivot 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 grouped numeric summary and a date-by-category pivot table for supplied wind speed and gust speed observation records.

## 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 wind-observations-grouped-summary-date-category-pivot-d902d977 -d '<json body>'
```

Example prompt: I have up to 200 rows of wind observation data with wind_speed_ms and gust_speed_ms readings across different station groups and dates — can you give me a grouped numeric summary and a date-by-category pivot for the wind_speed_ms field?

## When to prefer this

Choose this endpoint when you have a batch of wind observation records (up to 200 rows) tagged with station groups and dates, and you need both a grouped statistical summary and a date-category pivot in a single low-cost call. Ideal for offline/post-collection analysis of meteorological or IoT wind sensor data where no live lookup or forecasting is needed. Prefer over general analytics tools when you want a pre-packaged dual-report output for wind speed and gust data specifically.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, station_group, date, wind_speed_ms, gust_speed_ms) cause validation errors
- Invalid date format (must be YYYY-MM-DD) causes schema rejection
- Null values in numeric fields may affect summary statistics
- Invalid field enum value (only 'wind_speed_ms' or 'gust_speed_ms' accepted)
- Payment failure via x402 protocol results in 402 response with no data returned

## How this service works

Wind observations — Grouped numeric summary + Date by category pivot: Grouped numeric summary + Date by category pivot for supplied wind observations records (wind_speed_ms, gust_speed_ms). 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 grouped numeric summary (e.g. count, mean, min, max, std) of the chosen field (wind_speed_ms or gust_speed_ms) broken down by station_group, and (2) a pivot table with dates as rows and station groups as columns showing aggregated values for the selected field. Results are derived entirely from the supplied rows (up to 200) with no external data lookups.
