Weather

Two free services, no API keys needed. Use exec or web_fetch to query them.

wttr.in (primary)

Quick one-liner via exec:

curl -s "wttr.in/London?format=3"
# Output: London: ⛅️ +8°C

Compact format with multiple fields:

curl -s "wttr.in/London?format=%l:+%c+%t+%h+%w"
# Output: London: ⛅️ +8°C 71% ↙5km/h

Full forecast:

curl -s "wttr.in/London?T"

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

Tips:

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

Open-Meteo (fallback, JSON)

Free, no key, good for programmatic use. Use web_fetch:

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

Requires knowing coordinates. Look up coordinates first if needed:

web_fetch(url="https://geocoding-api.open-meteo.com/v1/search?name=London&count=1")

Returns JSON with temp, windspeed, weathercode.
