# Wind Observations — Duplicate Key Report + Date by Category Pivot

> Wind Observations — Duplicate Key Report + Date by 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 2026-10-29).

Analyzes up to 200 wind observation records to produce two local analytical reports: a duplicate key report and a date-by-category pivot table for wind_speed_ms or gust_speed_ms.

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 wind-observations-duplicate-key-report-date-by-category-pivot-99905d92 -d '<json body>'
```

Example prompt: I have 150 wind observation records with row IDs, station groups, dates, wind speeds, and gust speeds — can you run a duplicate key report and a date-by-category pivot on the wind_speed_ms field for me?

## When to prefer this

Choose this endpoint when you need to simultaneously check for duplicate record keys and produce a date-by-category pivot table on wind observation data (wind_speed_ms or gust_speed_ms) in a single low-cost call. It is best suited for data quality auditing and exploratory summarization of up to 200 wind records without requiring any external data sources, live feeds, or predictions.

## Known failure modes

- Input array is empty or missing — returns validation error
- More than 200 rows submitted — rejected with maxItems error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Field enum value not recognized — schema validation error
- Null values in numeric fields may affect aggregation results
- Malformed row objects missing required fields cause request rejection

## How this service works

Wind observations — Duplicate key report + Date by category pivot: Duplicate key report + 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 duplicate key report identifying rows with repeated row_id or station_group/date combinations, and (2) a date-by-category pivot table cross-tabulating the selected numeric field (wind_speed_ms or gust_speed_ms) across dates and station groups. All computation is performed locally on the supplied data with no external lookups.
