How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream Polymarket API response, passed through after successful USDC micropayment — typically JSON containing market data such as event names, outcome probabilities, trading volumes, resolution status, and order book information.
Example use cases
Check prediction market odds on event
“What are the current Polymarket odds for the next Fed rate decision market? Fetch the most recent market data.”
Retrieve open DeFi prediction markets
“Can you get me a list of currently open Polymarket markets related to crypto price predictions, using the /markets endpoint?”
Look up specific Polymarket market by ID
“Fetch the full details for Polymarket market ID 0x1234abcd from their markets endpoint so I can see the current probability and volume.”

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/polymarket-data?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need Polymarket prediction market data and want to pay per-call with USDC via the x402 micropayment protocol, avoiding API key management. Prefer this over direct Polymarket API access when operating in a web3-native agent context that supports x402 payments.
Side effects
- Payment failure: insufficient USDC balance or wallet not configured for x402 protocol
- Invalid path: Polymarket endpoint path not found returns upstream 404
- Malformed query parameters: invalid filters or pagination params return upstream 400
- Upstream unavailability: Polymarket API downtime causes 502 or timeout
- Rate limiting: excessive calls may trigger upstream or gateway throttling
