Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time prediction market crowd wisdom — implied probabilities, volume depth, and whale sentiment — specifically from Polymarket's orderbook. Prefer this over general news search when you want probabilistic forecasts rather than narrative coverage, and over static datasets when live, current odds are required for trading signals, macro positioning, or event-driven decision-making.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null market data
- Polymarket API rate limit or upstream outage causes stale or missing orderbook data
- Ambiguous topic string matches multiple markets — may return top result or require more specific query
- Payment failure (x402) if agent wallet lacks sufficient USDC balance
- Malformed or missing 'topic' parameter returns a 400 validation error
