Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/macro-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market orderbooks — particularly for macro events, crypto milestones, AI developments, or political outcomes. Prefer this over news sentiment tools when you want quantified implied probability with volume and whale flow data rather than qualitative opinion. Best suited for agents performing event-driven financial analysis, risk assessment, or real-time forecasting grounded in market participant behavior.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or low-confidence result
- Polymarket API or orderbook data temporarily unavailable — upstream fetch failure
- Topic query too vague or ambiguous — may return unrelated markets
- Payment not processed (HTTP 402) — x402 micropayment required before response is returned
- Rate limiting or timeout on downstream Polymarket data source
