Ambient Weather Network Realtime API (Socket.io WebSocket)

Ambient Weather Network Realtime API (Socket.io WebSocket) is a websocket from Ambient Weather providing weather data. A Socket.io-based WebSocket API that pushes live data from Ambient Weather's network of 250k+ personal/professional weather stations as each station reports. A Polymarket bot can subscribe to specific stations near a settlement point (e.g., NYC-area PWS close to Central Park / LaGuardia) to get sub-minute ground-truth temperature, humidity and rainfall for weather markets.

What data it provides

  • Live outdoor temperature (tempf) per station
  • Humidity (humidity / humidityin)
  • Precipitation: hourlyrainin, dailyrainin, eventrainin, totalrainin
  • Wind speed/gust/direction (windspeedmph, windgustmph, winddir)
  • Barometric pressure (baromrelin, baromabsin) and dew point / feels-like
  • Station/device metadata + geolocation (lat/lon) for picking stations near settlement sites

Features

  • Realtime push via Socket.io WebSocket at rt2.ambientweather.net (?api=1&applicationKey=...); subscribe with {apiKeys:[...]} and receive 'data' events on each station report
  • Network of 250,000+ personal/professional weather stations for hyperlocal coverage
  • REST companion API (api.ambientweather.net) for historical archive of your devices' past readings
  • JSON payloads; community SDKs/wrappers exist (Node, Python, Rust crate) plus official api-docs repo
  • Update cadence driven by each station's report interval (often ~every minute / few minutes), not a fixed server tick
  • Realtime API note: must reconnect/re-subscribe on disconnect; realtime subdomain (rt2) differs from REST
