Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/crypto-betting-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for crypto, macro, political, or AI events from Polymarket's prediction market. Prefer this over news sentiment APIs when you want market-priced probabilities with volume and whale-activity signals rather than qualitative sentiment. Ideal for agents that need a quantified probability signal backed by real money at stake.
Side effects

- Stale or delayed data if Polymarket API is temporarily unavailable
- Payment failure via x402 protocol if USDC balance is insufficient
- Rate limiting or 402 payment required error if micropayment handshake fails
