# Wind Observations — Grouped Numeric Summary + Keyed Dataset Comparison > Wind Observations — Grouped Numeric Summary + Keyed Dataset Comparison 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). Computes a grouped numeric summary and a keyed dataset comparison for up to 200 rows of wind observation records (wind_speed_ms, gust_speed_ms) using local analytical engines. ## Facts - Endpoint: POST https://market.datapackvibe.com/x402/assistant-ib26-weather-03-098?utm_source=zero.xyz - Price: $0.01/call - Payment: x402 - Status: unknown - Last checked: 2026-10-30 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/wind-observations-grouped-numeric-summary-keyed-dataset-comparison-eb029b3e - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_kHbCuTdLkyMzzW8apbn68 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-grouped-numeric-summary-keyed-dataset-comparison-eb029b3e -d '' ``` Example prompt: I have two sets of wind station readings — a primary dataset and a comparison dataset, each with up to 200 rows including station_group, date, wind_speed_ms, and gust_speed_ms — can you run a grouped numeric summary and a keyed dataset comparison on wind_speed_ms for me? ## When to prefer this Choose this endpoint when you have wind observation data (wind speed and gust speed in m/s) organized by station group and date, and you need both a grouped statistical summary AND a side-by-side comparison of two datasets in a single API call. It is ideal for offline/batch analysis of already-collected records where no live lookup, forecast, or external data enrichment is needed. At $0.01 USDC for both reports on up to 200 rows, it is cost-effective for bulk analytical tasks on structured weather datasets. ## Known failure modes - Input array exceeds 200 rows — request will be rejected - Missing required fields (row_id, station_group, date, wind_speed_ms, gust_speed_ms) in any row — validation error - Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure - Empty rows array (minItems: 1 not met) — request rejected - Duplicate row_id values may cause undefined comparison behavior - Non-numeric values for wind_speed_ms or gust_speed_ms where number is expected — type error ## How this service works Wind observations — Grouped numeric summary + Keyed dataset comparison: Grouped numeric summary + Keyed dataset comparison for supplied wind observations records (wind_speed_ms, gust_speed_ms). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows. ## Output Returns two analytical reports: (1) a grouped numeric summary that aggregates wind_speed_ms or gust_speed_ms statistics (e.g. mean, min, max, count) broken down by station_group, and (2) a keyed dataset comparison that identifies differences between the primary and secondary wind observation datasets on a row-by-row basis using row_id as the key. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "rows": { "type": "array", "items": { "type": "object", "required": [ "row_id", "station_group", "date", "wind_speed_ms", "gust_speed_ms" ], "properties": { "date": { "type": "string", "default": "", "pattern": "^\\d{4}-\\d{2}-\\d{2}$", "maxLength": 10 }, "row_id": { "type": "string", "default": "", "maxLength": 80, "minLength": 1 }, "gust_speed_ms": { "type": [ "number", "null" ], "maximum": 1000000000000, "minimum": -1000000000000 }, "station_group": { "type": "string", "default": "", "maxLength": 80 }, "wind_speed_ms": { "type": [ "number", "null" ], "maximum": 1000000000000, "minimum": -1000000000000 } }, "additionalProperties": false }, "default": [ { "date": "2026-10-01", "row_id": "row-1", "gust_speed_ms": 1, "station_group": "group-a", "wind_speed_ms": 10 }, { "date": "2026-10-02", "row_id": "row-2", "gust_speed_ms": 2, "station_group": "group-b", "wind_speed_ms": 20 }, { "date": "2026-10-03", "row_id": "row-3", "gust_speed_ms": 3, "station_group": "group-a", "wind_speed_ms": 15 }, { "date": "2026-10-04", "row_id": "row-4", "gust_speed_ms": 4, "station_group": "group-b", "wind_speed_ms": 30 } ], "maxItems": 200, "minItems": 1 }, "field": { "enum": [ "wind_speed_ms", "gust_speed_ms" ], "type": "string", "default": "wind_speed_ms" }, "other": { "type": "array", "items": { "type": "object", "required": [ "row_id", "station_group", "date", "wind_speed_ms", "gust_speed_ms" ], "properties": { "date": { "type": "string", "default": "", "pattern": "^\\d{4}-\\d{2}-\\d{2}$", "maxLength": 10 }, "row_id": { "type": "string", "default": "", "maxLength": 80, "minLength": 1 }, "gust_speed_ms": { "type": [ "number", "null" ], "maximum": 1000000000000, "minimum": -1000000000000 }, "station_group": { "type": "string", "default": "", "maxLength": 80 }, "wind_speed_ms": { "type": [ "number", "null" … (truncated) ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/wind-observations-grouped-numeric-summary-keyed-dataset-comparison-eb029b3e/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from market.datapackvibe.com](https://www.zero.xyz/host/market.datapackvibe.com/llms.txt)
