Endpoint
POSThttps://quanta-roan.vercel.app/api/service/polymarket-gamma?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to access Polymarket Gamma prediction market data and want per-call micropayment billing via the x402 protocol rather than managing a full API subscription. Ideal for AI agents that need on-demand, low-cost access to Polymarket odds and market metadata without committing to a recurring plan.
