How this service works
VAPE prediction_market_odds — Live crypto/Base-relevant prediction-market odds from Polymarket and Kalshi — market-implied probabilities on hacks, depegs, price thresholds, and protocol milestones, ranked by volume. Keyless, free-source data — no API key required either side.
Output
A list of prediction market entries (up to `limit`, default 20) from Polymarket and Kalshi, each including the market question, market-implied probability, and trading volume, ranked by volume — covering crypto/Base-relevant events like hacks, depegs, price thresholds, and protocol milestones.
Example use cases
Stablecoin depeg risk assessment
“What are the current market-implied odds of a major stablecoin like USDC or USDT losing its peg? Pull the latest prediction market probabilities from Polymarket and Kalshi so I can gauge how nervous the crowd really is right now.”
ETH price milestone crowd odds
“I want to know what prediction markets are saying about ETH hitting key price levels — like $5k or $10k — by end of year. Grab the top crypto price threshold markets ranked by volume so I can see where the real conviction is.”
DeFi protocol hack probability check
“Before I deploy a chunk of liquidity into a DeFi protocol, I want to see what prediction markets think the odds are of a major hack or exploit happening this year. Show me the highest-volume markets on crypto security events from Polymarket and Kalshi.”
Technical details
Endpoint
GEThttps://vape-x402.vapex402.workers.dev/data/prediction_market_oddsWhen to prefer
Choose this endpoint when you need live, crowd-sourced probability estimates on crypto-specific risk events (hacks, depegs, price milestones, protocol outcomes) aggregated from both Polymarket and Kalshi in a single call, ranked by volume. Prefer this over raw exchange data when you want market-implied probabilities rather than price feeds, and over building your own aggregator when you need a keyless, low-cost, ready-to-use prediction market summary.
Side effects
- Upstream Polymarket or Kalshi API unavailable — returns empty or partial results
- limit parameter out of range — may return default count or error
- No active markets matching crypto/Base scope at query time — returns empty list
- Network timeout to workers.dev edge — transient 5xx error
- Payment of 0.01 USDC via x402 not processed — 402 Payment Required response
