Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-wisdom probability estimates for macro, crypto, political, or AI events from Polymarket's prediction market. Prefer this over news or sentiment APIs when you want a single implied probability figure backed by real money at stake. Ideal for trading decision support, risk assessment, or any use case where market-consensus event probability is more valuable than qualitative opinion.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Topic query is too vague and matches multiple markets ambiguously
- Polymarket API rate limits or downtime cause upstream data unavailability
- Payment via x402 fails or USDC balance is insufficient, blocking the request
- Stale or delayed data if the underlying orderbook feed has a lag
