Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/polymarket-feed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events as priced by Polymarket traders. Prefer this over news APIs or sentiment tools when you want market-implied probabilities with volume and whale positioning signals rather than qualitative sentiment. Ideal for trading bots, research agents, or decision-support tools that need live prediction market consensus on a specific event.
Side effects
- Topic keyword matches no active Polymarket market — returns empty or no-match result
- Ambiguous topic resolves to wrong or unintended market
- Polymarket API or upstream data source is temporarily unavailable — upstream timeout or error
- Payment fails (x402) — endpoint returns 402 status before data is served
- Very new or niche topics may have low liquidity, resulting in unreliable probability estimates
