# Wind Observations — String Normalisation + Duplicate Key Report

> Wind Observations — String Normalisation + Duplicate Key Report 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).

Runs string normalisation and duplicate key detection on up to 200 wind observation records (wind_speed_ms, gust_speed_ms), returning two analytical reports.

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-string-normalisation-duplicate-key-report-0d41434a -d '<json body>'
```

Example prompt: Can you check these wind observation records for string normalisation issues and duplicate keys? I have up to 50 rows with fields like row_id, station_group, date, wind_speed_ms, and gust_speed_ms — I want both reports back.

## When to prefer this

Choose this endpoint when you need two simultaneous data quality reports — string normalisation and duplicate key detection — on wind observation records (wind_speed_ms, gust_speed_ms) in a single low-cost call. It is best suited for pre-ingestion data cleaning, batch QA, or pipeline validation steps where no external lookups, forecasts, or live data enrichment are needed.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, station_group, date, wind_speed_ms, gust_speed_ms) causes row rejection
- Invalid date format (not YYYY-MM-DD) triggers schema validation failure
- Malformed numeric values outside allowed range cause rejection
- Empty rows array returns an error
- Payment failure via x402 protocol prevents processing

## How this service works

Wind observations — String normalisation + Duplicate key report: String normalisation + Duplicate key report 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 independent analytical reports: (1) a string normalisation report identifying inconsistencies or anomalies in string fields (station_group, row_id, date) across submitted rows, and (2) a duplicate key report flagging rows with repeated key combinations, all processed locally against the up to 200 supplied wind observation records.
