# Wind Observations — Exact Row Deduplication + Explicit Missing-Value Fill

> Wind Observations — Exact Row Deduplication + Explicit 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 2026-10-30).

Deduplicates exact duplicate rows and fills missing values in wind observation records (wind_speed_ms, gust_speed_ms) for up to 200 rows, returning 2 analytical reports.

## 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-explicit-missing-value-fill-d157ca3d -d '<json body>'
```

Example prompt: Clean up my wind observation dataset: remove any exact duplicate rows and fill missing wind_speed_ms values using the median method. Here are my records with row_id, station_group, date, wind_speed_ms, and gust_speed_ms fields — up to 200 rows.

## When to prefer this

Choose this endpoint when you have wind observation data (with wind_speed_ms and/or gust_speed_ms fields) that requires both exact duplicate row removal and explicit missing-value imputation in a single call. It is ideal for preprocessing batches of up to 200 meteorological records before downstream analysis, reporting, or storage. Prefer it over general-purpose data cleaning tools when you specifically need wind-domain records cleaned with configurable fill strategies (zero, mean, or median) and want two focused analytical output reports at low cost ($0.01 USDC).

## Known failure modes

- Exceeding 200 rows returns a validation error
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Missing required fields (row_id, station_group, date) causes row-level errors
- Specifying an unsupported fill method or field enum value causes parameter rejection
- Submitting an empty rows array (minItems:1 violated) returns a validation error
- Payment failure via x402 protocol prevents processing

## How this service works

Wind observations — Exact row deduplication + Explicit missing-value fill: Exact row deduplication + 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

Two analytical reports per call covering: (1) exact row deduplication results identifying and removing duplicate wind observation records, and (2) explicit missing-value fill results showing which rows had null wind_speed_ms or gust_speed_ms values filled using the chosen method (zero, mean, or median). Reports are generated from the supplied data using local analytical engines — no external data or live lookups.
