How this service works
Live directional read from a real-money Kalshi BTC hourly (KXBTCD) trading model: current near-the-money strike, model probability vs market price, and computed edge. Informational model output, not investment advice — the strategy's real historical win rate / P&L is public at the bot's dashboard, good and bad stretches included.
Output
Returns the current near-the-money strike for the active KXBTCD (Kalshi BTC hourly) contract, the model's estimated probability for the directional outcome, the current Kalshi market price, and the computed edge (model probability minus market price). This is model output intended as informational signal, not investment advice.
Example use cases
Live edge check before placing trade
“Before I place a bet on the Kalshi BTC hourly market, pull the latest KXBTCD signal and tell me what edge the model sees and whether the model probability is meaningfully above or below the current market price.”
Automated hourly signal monitoring
“Every hour, fetch the Kalshi BTC hourly signal and alert me if the computed edge is above 3% — I want to know the strike, model probability, and market price whenever there's a strong opportunity.”
Backtested model credibility check
“I've heard about this BTC hourly Kalshi trading model — can you pull the current signal and tell me what the model says directionally, and remind me where I can see its real historical win rate and P&L?”

Endpoint
GEThttps://backend-production-69ff.up.railway.app/x402/signal/btc-hourly?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-money-calibrated directional signal specifically for Kalshi's BTC hourly prediction market (KXBTCD) with model probability versus market price comparison. Prefer this over generic crypto price feeds or sentiment APIs when the goal is to assess edge in a Kalshi prediction market contract rather than raw price movement. The endpoint is distinct from order execution — it provides read-only signal output backed by a publicly auditable historical track record.
