## Before you call it

1. Cache location keys. They don't change, and the lookup is the call worth saving
2. Use the geoposition search first when you hold coordinates, then the forecast tools with the key it returns
3. Send the key as a Bearer header, not in the MCP URL, so it stays out of logs
4. Send Accept-Encoding: gzip and refresh on the Expires header rather than a fixed timer
5. Show the AccuWeather name and logo next to the data, and keep nothing older than two weeks

## Connect
