# Wind Observations – Numeric Distribution & Missing-Value Fill

> Wind Observations – Numeric Distribution & Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Computes numeric distribution statistics and fills missing values (null) for wind_speed_ms and gust_speed_ms fields across up to 200 wind observation 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-numeric-distribution-missing-value-fill-ad7ef8c5 -d '<json body>'
```

Example prompt: I have up to 200 wind observation rows with some null wind_speed_ms and gust_speed_ms readings — can you compute the numeric distribution for wind_speed_ms and fill in all the missing values using the median method?

## When to prefer this

Choose this endpoint when you need to both characterize the distribution of wind speed or gust speed measurements and impute missing values in a single API call, without needing live weather lookups, forecasts, or external data. It is ideal for pre-processing historical or collected wind observation datasets before downstream analysis or model ingestion, and cost-effectively handles up to 200 rows for $0.01 USDC per call.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Unknown fill method value outside zero/mean/median is rejected
- Empty rows array causes a minItems validation failure
- Extremely large or small numeric values near the ±1e12 boundary may cause precision issues

## How this service works

Wind observations — Numeric distribution + Explicit missing-value fill: Numeric distribution + Explicit missing-value fill 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 for the specified wind field (wind_speed_ms or gust_speed_ms): (1) a numeric distribution report covering statistics such as min, max, mean, median, and spread across up to 200 rows; (2) a missing-value fill report showing which rows had null values and what replacement values were applied using the selected method (zero, mean, or median).
