How this service works
🆕 Queries Polymarket's Gamma CLOB for active prediction markets. Resolves event outcome probabilities (Yes/No %), 24h volume, liquidity, and resolution date in one call. Designed for AI agents that need a real-world reality check before trading, hedging, or rebalancing treasury. Pass query= (e.g. 'fed', 'btc', 'kraken-ipo-in-2025'). A probabilistic signal, not financial advice.
Output
Returns active Polymarket prediction market data for the queried topic, including: Yes/No outcome probabilities (as percentages), 24-hour trading volume, available liquidity, resolution date, and the market question text. Multiple matching markets may be returned if several are active for the query.
Example use cases
Pre-trade probability reality check
“Before I rebalance my treasury, what does Polymarket say about the probability of BTC hitting $100k by end of year? Show me the Yes/No odds, liquidity, and resolution date.”
Macro event hedging signal
“What are the current prediction market odds for a US recession in 2025? I want the Yes/No percentages and how much volume has traded in the last 24 hours.”
IPO timing assessment
“What's the Polymarket probability of a Kraken IPO happening in 2025? Give me the current odds and how much liquidity is in that market.”

Endpoint
GEThttps://402.com.tr/api/x402/polymarket-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time crowd-sourced probability signal from Polymarket's prediction markets before making a trading, hedging, or rebalancing decision. Prefer this over general news or sentiment APIs when you want a market-priced probability with liquidity data and a defined resolution date. Best suited for macro events, crypto milestones, regulatory decisions, and corporate events where Polymarket has active markets.
Side effects
- No active markets found for the query — returns empty results or a not-found response
- Query too broad or ambiguous — may return unrelated markets
- Market recently resolved — endpoint may return stale or no data
- Gamma CLOB API unavailable — upstream timeout or error
- Rate limiting or payment failure — 402 payment required error
