Endpoint
GEThttps://whale-momentum.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, political, or AI events sourced directly from Polymarket orderbooks. Prefer this over news sentiment APIs when you want market-implied probabilities backed by actual money, or over static odds providers when you need live orderbook depth and whale positioning data.
Side effects
- Topic keyword too vague or returns no matching market — response may be empty or return nearest match
- Polymarket API unavailability causes upstream data fetch failure
- Payment not processed (HTTP 402) if x402 micropayment is not properly handled
- Rate limiting if too many requests are made in a short window
- Topic string too short (minLength:1 required) triggers validation error
