Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/polymarket-alpha?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for binary macro, crypto, political, or AI events, particularly when you want market-implied odds rather than model predictions. It is ideal for agents monitoring live event probabilities, performing sentiment analysis on prediction markets, or incorporating Polymarket whale activity into financial decision logic. Prefer this over news search endpoints when you want a quantified probability signal, not narrative coverage.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Topic is too ambiguous and matches multiple unrelated markets — may return mixed or irrelevant data
- Polymarket API or data feed is temporarily unavailable — upstream timeout or error
- Payment failure via x402 protocol — call not executed if USDC payment is rejected
- Rate limiting or quota exceeded — HTTP 429 or 402 payment required response
