Endpoint
POSThttps://onchain-risk.agentdiet.dev/v1/polymarket-alpha?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, crowd-sourced probability estimates from a live decentralized prediction market (Polymarket) rather than model-generated forecasts or news sentiment. Ideal for macro, crypto, and AI-policy events where market-implied probabilities and whale positioning provide unique signal unavailable from traditional data sources.
Side effects
- Topic keyword matches no active Polymarket market — returns empty or no-results response
- Polymarket API or data feed is temporarily unavailable — service may return an error or stale data
- Ambiguous topic keyword matches multiple markets — response may include multiple or unexpected markets
- Payment not processed (x402 flow failure) — endpoint returns 402 before delivering data
- Rate limiting or quota exceeded — returns error after repeated rapid calls
