# Wind Observations — Exact Row Deduplication + Trailing Mean Series

> Wind Observations — Exact Row Deduplication + Trailing Mean Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-03).

Deduplicates exact rows and computes a trailing mean series for supplied wind observation records (wind_speed_ms or gust_speed_ms) across up to 200 rows.

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-exact-row-deduplication-trailing-mean-series-b22d86ed -d '<json body>'
```

Example prompt: I have 50 wind observation rows with station_group, date, wind_speed_ms, and gust_speed_ms — can you deduplicate exact duplicate rows and compute a trailing mean series for wind_speed_ms using a window of 5?

## When to prefer this

Choose this endpoint when you have a batch of up to 200 wind observation records that need both exact duplicate removal and a rolling mean time series computed locally — without any live data lookup, external forecasting, or prediction. Ideal for data cleaning and trend smoothing pipelines on historical or ingested wind sensor data.

## Known failure modes

- Fewer than 1 row supplied — rejected by minItems validation
- More than 200 rows supplied — rejected by maxItems limit
- Window size larger than number of rows — trailing mean may produce nulls or partial results
- Invalid date format (not YYYY-MM-DD) — schema pattern validation error
- Missing required fields (row_id, station_group, date, wind_speed_ms, gust_speed_ms) — request rejected
- Non-numeric values in wind_speed_ms or gust_speed_ms — type validation failure
- Payment not included or insufficient — x402 payment required error

## How this service works

Wind observations — Exact row deduplication + Trailing mean series: Exact row deduplication + Trailing mean series 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 reports for the supplied wind observation data: (1) an exact row deduplication report identifying and removing duplicate records, and (2) a trailing mean series computed over the specified window for the chosen field (wind_speed_ms or gust_speed_ms), grouped by station and date order.
