// 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.

→ /v1/stations/{icao}/observations

→ /v1/stations/{icao}/forecasts

// 03 · how it works

One API key. Three lines to live data.

# list active weather markets
curl "https://api.wxsignals.com/v1/markets?city=Tokyo&limit=10" \
  -H "X-API-Key: $WXSIGNALS_KEY"

import requests

r = requests.get(
    "https://api.wxsignals.com/v1/markets",
    headers={"X-API-Key": "pwk_..."},
    params={"city": "Tokyo", "limit": 10},
)
markets = r.json()["markets"]

const r = await fetch(
  "https://api.wxsignals.com/v1/markets?city=Tokyo&limit=10",
  { headers: { "X-API-Key": process.env.WXSIGNALS_KEY } }
);
const { markets } = await r.json();
