Weather
Free: wttr.in (text) and Open-Meteo (JSON). No keys.
Default: one small request
Prefer a short forecast to save tokens and latency:
- 1–2 days (typical “today / tomorrow / morgen”):
https://wttr.in/PLACE?2&m— spaces →+.2= two-day forecast,m= metric. - Full multi-day table only if the user asks for the week, several days, or
?2is not enough:https://wttr.in/PLACE?T&m(T= full terminal layout).
If the body looks like a real forecast → summarize and stop. No Open-Meteo unless wttr failed, error page, or you need JSON.
How to answer
Chat, not a datasheet: short intro on how it _feels_, then compact day lines (date, °C, rain when it matters). No lat/long, WMO codes, or bold datasheet headings unless the user asked for technical detail.
wttr.in (curl / fetch)
| Goal | Example |
|---|---|
| Short (default), 1–2 days | curl -s "wttr.in/London?2&m" |
| Full week-style table | curl -s "wttr.in/London?T&m" |
| One line now | curl -s "wttr.in/London?format=3" |
| Custom one-liner | curl -s "wttr.in/London?format=%l:+%c+%t+%h+%w" |
Tips: + for spaces; ?m / ?u units; ?1 today only; ?0 now only; airports wttr.in/JFK; PNG wttr.in/Berlin.png.
Open-Meteo (fallback)
Hosts: geocoding-api.open-meteo.com, api.open-meteo.com only — not open-meteo.com HTML.
Flow (max 2 geocode + 1 forecast):
https://geocoding-api.open-meteo.com/v1/search?name=PLACE&count=10(spaces as+)- If
resultsmissing/empty: one retry — shortername+countryCodePick the row whoseadmin3/admin2/admin1matches the user phrase. https://api.open-meteo.com/v1/forecast?latitude=LAT&longitude=LON&daily=temperature_2m_max,temperature_2m_min,precipitation_probability_max,weathercode&forecast_days=7&timezone=auto— extendforecast_daysto 7–16 if they asked for more days.
Current only: curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12¤t_weather=true"
JSON: daily.time, temperature_2m_max / _min, precipitation_probability_max, weathercode — translate codes to plain words (see weather codes); never paste codes to the user unless asked.
When to use
Named place — current weather or forecast.
