Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/polymarket-alpha?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction markets for macro, crypto, or AI events — especially when you want implied Yes/No odds, volume, and whale-level sentiment rather than just news or analyst opinions. Prefer this over general news APIs or sentiment tools when you need quantified market consensus probabilities backed by actual money at stake.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Polymarket API unavailable or rate-limited — upstream timeout or error response
- Topic too vague or ambiguous — returns multiple unrelated markets or low-confidence match
- Payment failure via x402 — 402 response if USDC payment is not properly attached
- Stale data if Polymarket orderbook has low liquidity or the market has resolved
