Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/macro-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events sourced directly from Polymarket's live orderbooks. It is ideal for agents that need to gauge market consensus, whale positioning, or implied odds on near-term events without building a Polymarket integration from scratch. Prefer this over general news or sentiment APIs when you specifically need quantified probability rather than qualitative opinion.
Side effects
- No matching market found for the given topic keyword — returns empty or null results
- Ambiguous topic matches multiple markets — response may include multiple or unexpected markets
- Stale data if Polymarket API is delayed — probabilities may lag real-time market state
- Payment failure (HTTP 402) if x402 micropayment is not completed before query
- Rate limiting or throttling if too many queries are made in rapid succession
