// 02 · what you get

Three layers of market intelligence,
one API.

01 / DATA

Live market feed

Active Polymarket weather markets, refreshed every 30 seconds. Yes/no prices, bid/ask depth, 24h volume, spread — every bucket of every market.

/v1/markets
/v1/markets/{id}
/v1/markets/{id}/snapshots
02 / HISTORY

A growing history

Every price tick since launch. Use it to backtest your own strategies or analyze how each city's markets behave around resolution. Dataset grows daily.

/v1/markets/{id}/prices
filter by outcome, time
03 / WEATHER

Station data SOON

METAR observations and NOAA forecasts for the stations that resolve each market. The raw signal you need to build your own models — no opinions baked in.

// 03 · how it works

One API key. Three lines to live data.

# list active weather markets

  -H "X-API-Key: $WXSIGNALS_KEY"
// 04 · the models

Best-in-class regional models,
side-by-side.

Each station is automatically routed to its top 3 forecast models — two regional experts plus one global reference. You receive all three in a single API call so you can build your own ensemble, weight them by recency, or pick the one that fits your strategy.
