Example use cases
Live prediction market odds lookup

Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/polymarket-bridge?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need programmatic access to Polymarket prediction market data and are operating in a web3/x402 micropayment context. Prefer this over direct Polymarket API access when your agent infrastructure is already set up for x402 payments and you want per-call billing at $0.01 USDC rather than managing API keys or subscriptions.
Side effects
- Payment failure: insufficient USDC balance or wallet not configured for x402 micropayments
- Invalid path: the specified Polymarket API path does not exist, returning a 404 from upstream
- Malformed query or body: Polymarket rejects the forwarded request due to invalid parameters
- Polymarket API downtime: upstream service unavailable, returning a 502 or 503
- Rate limiting: Polymarket upstream rate-limits the gateway IP, causing 429 errors
