Getting Started

Choose your integration method

Athenium offers two ways to access weather intelligence:

MCP Server (recommended for AI workflows)

The Weather MCP server lets AI assistants query weather data using natural language. No API integration code needed.

1. Add the MCP server to your AI client (see quickstart)
2. Authorize via OAuth when prompted (or use an API key with the Weather Risk MCP)
3. Start asking questions about weather data

REST APIs (for programmatic access)

5 OpenAPI 3.1 APIs for direct integration into your applications.

1. Get an API key from customer.support@athenium.com
2. Review the API reference
3. Make your first request:

curl "https://api.atheniumanalytics.com/v2/forecast?lat=39.74&lon=-104.99&startDate=2025-03-15&endDate=2025-03-21&userKey=YOUR_API_KEY"
