How this service works
The live feed a Kalshi event settles on, from Kalshi's free live_data tier: a crypto event returns the CF Benchmarks price series, candlesticks (15M, 1M) and the maturity time; an economic-data event (CPI, jobs) returns the provider's series with the target period. Pass an eventTicker, or a seriesTicker (e.g. KXBTC) and the soonest open event is resolved for you. The type field names the schema of details.
Output
Returns a JSON object containing the latest price point with timestamp, a time series array, OHLC candlestick data grouped by interval, event metadata (ticker, maturity timestamp), the data source ('kalshi'), available range options, and a flag indicating whether the event is historical or live.
Example use cases
Monitor live BTC Kalshi contract
“What's the current price and latest candlestick data for the Kalshi BTC event KXBTC-26SEP1817? Give me the 1-hour chart view.”
Track CPI prediction market
“Fetch the live Kalshi data for the KXCPI series — I want to see the latest value, maturity time, and a 1-day chart range with up to 500 data points.”
Crypto event price alert
“Get me the most recent price point and OHLC candlesticks for the Kalshi event KXBTC-26SEP1817 using a 15-minute range so I can track short-term movement.”
Technical details
Endpoint
POSThttps://agent402.tools/api/kalshi-live-data?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live or recent Kalshi prediction market data — including price series, OHLC candlesticks, and event maturity details — for crypto or macro events like BTC price or CPI outcomes. Prefer it over generic crypto price APIs when you specifically need Kalshi contract pricing or want to track a prediction market rather than a spot exchange price.
Side effects
- Invalid or unknown eventTicker/seriesTicker returns an error or empty result
- Requesting a range not supported by the event type may return null range
- Exceeding limit max of 1000 is silently capped
- Event already resolved may return isHistorical=true with no live data
- x402 payment failure if insufficient USDC balance
