# Wind Observations — Exact Row Deduplication + Secondary-Measure Weighted Mean

> Wind Observations — Exact Row Deduplication + 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 2026-10-29).

Deduplicates wind observation records exactly and computes a secondary-measure weighted mean across up to 200 rows of wind speed and gust speed data.

## 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-exact-row-deduplication-secondary-measure-weighted-33579f53 -d '<json body>'
```

Example prompt: Can you deduplicate these wind observation records and compute the weighted mean for wind_speed_ms? I have up to 50 rows with fields: row_id, station_group, date, wind_speed_ms, and gust_speed_ms — I need both the exact row deduplication report and the secondary-measure weighted mean.

## When to prefer this

Choose this endpoint when you have raw wind observation records (with wind speed and gust speed) that may contain exact duplicate rows and you need both a deduplicated dataset and a weighted mean of one of the two measures. Ideal for data cleaning and QA pipelines for meteorological or environmental sensor data, especially when working in batches of up to 200 rows with no need for live lookups or external data enrichment.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, station_group, date, wind_speed_ms, gust_speed_ms) causes validation error
- Invalid date format (not YYYY-MM-DD) fails schema validation
- Null values for both wind_speed_ms and gust_speed_ms may affect weighted mean computation
- Empty rows array rejected by minItems:1 constraint

## How this service works

Wind observations — Exact row deduplication + Secondary-measure weighted mean: Exact row deduplication + Secondary-measure weighted mean 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) the result of exact row deduplication applied to the submitted wind observation records, and (2) a secondary-measure weighted mean computed over the selected field (wind_speed_ms or gust_speed_ms), both processed locally against up to 200 supplied rows.
