How this service works
Paid data APIs for AI agents: prediction-market analytics, weather intelligence, weather×market edge signals, and SEC/gov data. Paid endpoints use the x402 protocol (HTTP 402 + USDC on Base): call without payment to receive requirements, retry with an X-PAYMENT header. Machine-readable catalog: /llms.txt. Per-endpoint docs: /docs/{id}.
Output
A JSON object containing: aggregated consensus probability of Cat 3+ US hurricane landfall, per-venue breakdown (Kalshi and Polymarket) with implied probability, 24-hour USD volume, and liquidity score for each, the divergence between venues, the 1-hour probability move, resolution date (November 30), resolution criteria summary (NHC-confirmed Cat 3+ landfall), and metadata including freshness timestamp, data mode (live/realtime), and documentation URL.
Example use cases
Hurricane season risk briefing
“What's the latest cross-market probability that a major hurricane hits the US coast before December? I want to see the Kalshi and Polymarket numbers side by side and whether they're diverging.”
Catastrophe bond desk monitoring
“Pull me the current Cat 3+ US hurricane landfall probability from prediction markets right now — I need the implied probability, 24-hour volume, and liquidity scores from each venue.”
Weather-driven trading signal check
“Has the major hurricane US landfall probability moved in the last hour on Kalshi or Polymarket? Give me the current consensus probability and the one-hour change.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/evergreen/next-hurricane-cat3-us-landfallWhen to prefer
Choose this endpoint when you need a real-time, multi-venue consensus probability for a major (Cat 3+) hurricane making US landfall — especially when you want both Kalshi and Polymarket odds in a single call with liquidity and volume metadata. Prefer this over scraping individual venues manually, over weather-service storm-track APIs (which give physical forecasts, not market-implied probabilities), or over generic prediction-market search endpoints that require you to identify and query specific market IDs yourself.
Side effects
- HTTP 402 returned without X-PAYMENT header — caller must parse payment requirements and retry with USDC payment on Base
- Payment amount or token mismatch causes rejection
- Prediction market venues temporarily unavailable — stale or partial data may be returned
- No active market for the current season — endpoint may return empty or rolled-over data
- Network timeout on aggregation from upstream venues
