# Wind Observations — Duplicate Key Report + Category Frequencies

> Wind Observations — Duplicate Key Report + Category Frequencies 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).

Analyzes up to 200 wind observation records to produce a duplicate key report and category frequency breakdown for wind_speed_ms and gust_speed_ms fields.

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-duplicate-key-report-category-frequencies-ea74aeae -d '<json body>'
```

Example prompt: Check my wind observation records for duplicate row keys and give me a category frequency breakdown — here are 4 rows: row-1 on 2026-10-01 in group-a with wind_speed 10 m/s and gust 1 m/s, row-2 on 2026-10-02 in group-b with wind 20 m/s and gust 2 m/s, row-3 on 2026-10-03 in group-a with wind 15 m/s and gust 3 m/s, and row-4 on 2026-10-04 in group-b with wind 30 m/s and gust 4 m/s.

## When to prefer this

Choose this endpoint when you need to simultaneously audit a wind observation dataset for duplicate row keys AND understand the distribution of categorical values (station groups) — all in a single API call at low cost. It is ideal for data quality checks on meteorological datasets before downstream analysis, and when you have up to 200 rows of wind speed and gust speed records. Prefer this over generic deduplication tools when your data specifically includes wind_speed_ms and gust_speed_ms fields with station group categorization.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, station_group, date, wind_speed_ms, gust_speed_ms) cause validation errors
- Invalid date format (must match YYYY-MM-DD pattern) causes schema rejection
- Empty rows array (minItems: 1 not satisfied) results in error
- row_id exceeding 80 characters triggers schema validation failure

## How this service works

Wind observations — Duplicate key report + Category frequencies: Duplicate key report + Category frequencies 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 independent analytical reports: (1) a duplicate key report identifying any rows sharing the same key within the supplied wind observation records, and (2) category frequency counts for the categorical fields (station_group) across all supplied rows — covering up to 200 input records.
