Two free services, no API keys needed. Use the http_client tool for all requests.

wttr.in (primary)

Quick one-liner:

http_client(method="GET", url="https://wttr.in/London?format=3")

Compact format:

http_client(method="GET", url="https://wttr.in/London?format=%l:+%c+%t+%h+%w")

Full forecast:

http_client(method="GET", url="https://wttr.in/London?T")

Format codes: %c condition, %t temp, %h humidity, %w wind, %l location, %m moon

Tips:

• URL-encode spaces: wttr.in/New+York
• Airport codes: wttr.in/JFK
• Units: ?m (metric) ?u (USCS)
• Today only: ?1 / Current only: ?0

Open-Meteo (JSON, for programmatic use)

Free, no key, returns structured JSON:

http_client(method="GET", url="https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&current_weather=true")

Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode.
