Endpoint
GEThttps://workflows.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, political, or AI events from Polymarket's live orderbooks, especially when whale sentiment and volume context matter. Prefer this over static news or analyst forecasts when you want market-implied probabilities rather than opinion-based assessments.
Side effects
- No matching market found for the given topic keyword — returns empty or null results
- Stale data if Polymarket API is experiencing downtime or rate limits
- Ambiguous topic keyword matching multiple markets — results may be for wrong market
- Payment failure (HTTP 402) if USDC balance is insufficient for the $0.01 per-call fee
- Generic 500 error if the upstream Polymarket orderbook API is unavailable
