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
Returns a JSON object with the current aggregated prediction market probability for the Super Bowl winner, including: team slug, question text, per-venue breakdown (Kalshi/Polymarket) with implied probability, 24h USD volume, and liquidity score, plus aggregate divergence across venues, 1-hour price movement, resolution date, and metadata including data freshness and source list.
Example use cases
Live Super Bowl odds dashboard
“Pull the latest prediction market probabilities for the Super Bowl winner right now — I want to see the implied odds, 24-hour volume, and how much they've moved in the last hour.”
Checking Chiefs championship chances
“What's the current market-implied probability that the Kansas City Chiefs win the next Super Bowl, according to prediction markets like Kalshi?”
Sports betting edge signal for newsletter
“Fetch today's real-time Super Bowl winner odds from prediction markets so I can include the current favorite and their probability in my weekly sports newsletter.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/evergreen/superbowl-winnerWhen to prefer
Choose this endpoint when you need real-time, aggregated prediction market probability for the Super Bowl winner from multiple venues (Kalshi, Polymarket) in a single call, with liquidity and volume metadata. Prefer it over scraping individual venue APIs when you want normalized, cross-venue signals with freshness guarantees. It is especially suited for AI agents that need a single authoritative probability figure with market microstructure context (volume, liquidity, 1h momentum).
Side effects
- 402 Payment Required — no X-PAYMENT header provided; response includes USDC payment requirements for retry
- Invalid or expired payment header — returns payment error
- Market data temporarily unavailable — upstream venue outage may cause stale or missing per-venue data
- Rate limit exceeded — too many requests in a short window
