Technical details
Endpoint
POSThttps://polymarket-odds.agentdiet.dev/v1/macro-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, AI, or geopolitical events from Polymarket's live orderbooks — particularly when you want implied probabilities derived from actual financial stakes rather than polling or sentiment analysis. Prefer this over generic news or sentiment APIs when you need quantified market consensus (e.g. 73% Yes) with volume and whale activity context.
Side effects
- Topic keyword too vague — no matching Polymarket market found, returns empty or low-confidence results
- Polymarket API unavailable or rate-limited — upstream timeout or partial data
- Misspelled or ambiguous topic returns wrong market odds
- Very niche or newly created markets may have low liquidity and unreliable implied probabilities
- Payment failure via x402 — call not executed if USDC balance insufficient
