How this service works
Live directional read from the Kalshi bot's SOL hourly (KXSOLD) model (same volatility model as the BTC and ETH signals): 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
A JSON object containing: the current SOL spot price, the near-the-money Kalshi strike price, the model's probability estimate, the market's implied probability, the computed directional edge, the recommended side (yes/no), the active event and market ticker, the contract close time, annualized volatility, and the timestamp when the signal was generated.
Example use cases
Live SOL edge monitoring for trading bot
“Check the current Kalshi SOL hourly signal and tell me if the model edge is above 0.05 — include the strike, side, model probability, and market probability so I can decide whether to place a trade.”
Comparing SOL vs ETH Kalshi mispricing
“Pull the latest Kalshi SOL hourly signal and compare the model probability to the market price — I want to see how big the edge is and which direction the model is leaning right now.”
Hourly SOL volatility snapshot
“Get me the current SOL Kalshi hourly signal including the annualized volatility and the close time for the active contract — I'm tracking how vol changes throughout the day.”
Technical details
Endpoint
GEThttps://backend-production-69ff.up.railway.app/x402/signal/sol-hourly?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a live, model-driven directional signal specifically for SOL on Kalshi hourly contracts, including quantified edge. Prefer this over generic price feeds when you want model probability vs market probability comparison and a computed edge for prediction market trading decisions. Use the sibling BTC or ETH endpoints for those assets instead.
Side effects
- No active hourly contract available — close time may have passed and the next contract hasn't opened yet
- Stale signal — generatedAt timestamp is older than expected if the underlying model hasn't refreshed
- Invalid or unexpected response structure if the Railway backend is down or overloaded
- Payment failure — x402 payment of $0.02 USDC not accepted, resulting in 402 response
- Edge may be near zero if model and market probabilities are tightly aligned
