Build and run Xweather Weather API request URLs for data.api.xweather.com from plain-language requirements. Use when a task mentions the Xweather or legacy Aeris API, weather endpoints such as observations, conditions, forecasts, alerts, lightning, air quality, tropical cyclones, tides, or road weather; asks for an API URL or query; needs help debugging an empty or failed request; asks about access costs, endpoint multipliers, rate limits, or allowance usage; or needs guidance for the hosted Xweather MCP server at mcp.api.xweather.com, including availability, connection, authentication, and tool scoping. Also covers Xweather's attribution requirement — the 'Powered by Vaisala Xweather' credit and logo rules that apply wherever Xweather data or imagery is displayed.

## Install

```sh
git clone https://github.com/vaisala-xweather/xweather-agent-skills /tmp/xweather-agent-skills && ln -s /tmp/xweather-agent-skills/plugins/xweather/skills/weather-api ~/.claude/skills/weather-api
```

## From README

Xweather Weather API URL builder Turn a description of wanted weather data into a correct data.api.xweather.com URL — and, when credentials are available, execute it and return the data alongside the URL. Request anatomy | Segment | Example | Notes | |---|---|---| | endpoint | observations, conditions/summary | What data. 59 of them — see references/endpoints.md. | | action | closest, within, search, route, contains, affects | How to look it up. Omitted entirely for :id and :all. | | :id | seattle,wa, 98109, 44.97,-93.26, KMSP | The place or record identifier. Goes in p= instead when an action occupies the path slot. | | params | filter=, query=, fields=, limit=, from=/to=, format= | Shape the result. | | credentials | clientid + clientsecret | Query params on every request; no header form exists. | api.aerisapi.com is the legacy host and still works — always emit data.api.xweather.com.
