How this service works
TCG card grading, conformal risk forecasting, and market intelligence. Powered by x402 micropayments — USDC on Base, USDC on Solana, or USDG on Robinhood Chain; the 402 offers all three and the agent picks a leg. Free tools require no payment. Paid tools return HTTP 402 — sign a payment and retry with the payment proof header.
Output
Returns a JSON object with a status field, a scan_type identifying the arbitrage strategy used, and an array of opportunities listing detected discrepancies between NWS forecast temperatures and Kalshi derivative prices that may represent exploitable edges.
Example use cases
Identify underpriced temperature contracts before earnings
“Look for mispriced temperature derivatives on Kalshi where the NWS forecast is cooler or warmer than what the market's currently pricing in — I want to catch these inefficiencies before they get corrected.”
Monitor precipitation arbitrage across regions
“Scan the Kalshi precipitation markets against the latest NWS data and flag anywhere we're seeing a statistical edge — especially in regions where the forecasts have high confidence but prices haven't caught up.”
Track wind speed derivative mispricings daily
“Check what NWS is predicting for wind speeds over the next week and compare it against Kalski's current wind derivative prices — alert me to any meaningful gaps that could represent a profitable trade.”
