Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/polymarket-alpha?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI-related events sourced directly from Polymarket orderbooks. It is ideal for agents that need to quantify market consensus on binary outcomes (Yes/No), monitor whale sentiment, or compare implied probabilities against other forecasting sources. Prefer this over general news or sentiment APIs when you want financial-market-calibrated probability rather than qualitative opinion.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null market data
- Polymarket API or upstream data source unavailable — endpoint may time out or return an error
- Ambiguous topic keyword matching multiple unrelated markets — response may include irrelevant markets
- Payment required (HTTP 402) if x402 micropayment header is not included or USDC balance is insufficient
- Stale data if Polymarket orderbook has low liquidity for the queried market
