Signal Sol Hourly

by Kalshi SOL Hourly Signal in Markets & finance

x402 APIPassing, checked 5 h ago

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.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://backend-production-69ff.up.railway.app/x402/signal/sol-hourly'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://backend-production-69ff.up.railway.app/x402/signal/sol-hourly' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
