Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/polymarket-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs current Polymarket prediction market odds on a specific topic without maintaining a direct Polymarket API integration. It is ideal for agents operating in an x402 micropayment environment settling in USDC on Base, where per-call pricing ($0.01) is preferable to subscription costs. Best used for one-off or infrequent odds lookups rather than high-frequency streaming data needs.
Side effects
- Payment not settled in USDC on Base — 402 Payment Required returned
- Invalid or missing 'topic' query parameter — may return empty or generic results
- Polymarket API unavailable upstream — data field may be empty or error returned
- Unsupported HTTP method used — schema requires GET or POST
