How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream response from the Polymarket CLOB API is passed through after successful x402 micropayment verification — including order book snapshots, trade data, market metadata, or any other CLOB API response, along with the content type header.
Example use cases
Check Polymarket market odds
“What are the current yes/no prices on the Polymarket market for whether the US will enter a recession in 2025? Give me the latest CLOB data.”
Fetch open orders for a market
“Show me all open orders on the Polymarket CLOB for the next US presidential election market — I want to see depth of book.”
Query recent trade history on Polymarket
“Get me the recent trade history from the Polymarket CLOB for the 'Bitcoin above $100k by end of year' market so I can analyze price movement.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/polymarket-clob?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use, no-subscription access to the Polymarket CLOB API and are already operating in an x402 micropayment context. Ideal for AI agents that need sporadic or low-volume access to Polymarket order book, pricing, or trade data without managing a Polymarket API key directly. Prefer over direct Polymarket API access when operating in a web3/DeFi agent stack that supports x402 payments natively.
Side effects
- Payment failure — insufficient USDC balance or invalid x402 payment header returns 402
- Invalid path — unrecognized or malformed Polymarket CLOB path returns upstream 404
- Malformed JSON body — invalid body string forwarded upstream may return 400
- Polymarket CLOB API downtime — upstream unavailability results in 502 or timeout
- Rate limiting — excessive calls may be throttled by upstream Polymarket API
