Technical details
Endpoint
POSThttps://polymarket-markets.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need live, structured Polymarket prediction-market data without an API key, especially for querying active markets with volume and liquidity. Prefer this over directly calling Polymarket's Gamma API when you need a simple POST interface with per-call micropayment billing and no authentication setup.
Side effects
- Upstream Polymarket Gamma API unavailable — no charge applied, empty or error response returned
- Invalid limit value (non-integer) — likely 400 bad request
- Missing or malformed X-WALLET header — may result in rejection or billing error after free-call quota exhausted
- Rate limiting or quota exceeded per wallet address
- Network timeout reaching the proxy service
