The API covers 139 endpoints across 16 categories including weather, transport, economy, health, environment, parliament, police, education, and more. Args: - query (string, optional): Keyword to search across endpoint names, descriptions, and paths - category (string, optional): Filter by category name When called with no arguments, returns all available categories with endpoint counts. Examples: - Find weather endpoints: query="weather" - Browse transport category: category="Transport" - Find pension info: query="pension" - List all categories: (no arguments) Returns: Matching endpoints with their paths, parameters, and descriptions.govdata_queryCall any Apiverket API endpoint to retrieve Swedish government data. Use govdata_discover first to find the right endpoint path and required parameters. Then call this tool with the endpoint path and any path/query parameters. Args: - endpoint (string, required): The API path (e.g. "/v1/weather/{city}") - path_params (object, optional): Values for path parameters like {city}, {code}, {id} - query_params (object, optional): Query string parameters (q, limit, offset, lat, lon, etc.) Examples: - Current weather in Stockholm: endpoint="/v1/weather/{city}", path_params={"city": "stockholm"} - Search jobs: endpoint="/v1/jobs/search", query_params={"q": "developer", "limit": 5} - Train departures from Stockholm Central: endpoint="/v1/transport/trains/{station}", path_params={"station": "Cst"} - Exchange rates: endpoint="/v1/rates" - Population by municipality: endpoint="/v1/population/{municipalityCode}", path_params={"municipalityCode": "0180"} - Police events in Stockholm: endpoint="/v1/police/events", query_params={"location": "Stockholm", "limit": 10} - Find EV chargers near a location: endpoint="/v1/infrastructure/ev-chargers", query_params={"lat": 59.33, "lon": 18.07} Returns: The API response as JSON, containing a "meta" envelope with request info and a "data" object with the actual data. Error handling: - Returns clear error messages if the API is unreachable, the endpoint doesn't exist, or parameters are invalid - Large responses are automatically truncated with pagination guidance
