polymarket code: how to use it for fast arbitrage

If you searched for "polymarket code" you likely want to know how to interact programmatically with Polymarket or how bots read its markets. Polymarket exposes three REST APIs and a market WebSocket; the CLOB surface is where order books live. PolyArb integrates with those exact endpoints to monitor spreads and execute arbitrage with low latency.

What "polymarket code" usually refers to

Traders mean one of three things by "polymarket code": calling the Gamma, Data, or CLOB REST APIs; connecting to the market WebSocket for real-time book updates; or using the Relayer and CTF primitives to split, merge, and redeem outcome tokens. The CLOB is where you’ll read best_bid_ask, midpoint, and order-book depth for arbitrage opportunities. Polymarket’s exact API base URLs are public and required for correct integration: https://gamma-api.polymarket.com, https://data-api.polymarket.com, and https://clob.polymarket.com. The market WebSocket is wss://ws-subscriptions-clob.polymarket.com/ws/market.

How developers actually wire bots to Polymarket

A practical bot subscribes to the WebSocket for price_change and best_bid_ask events, and falls back to CLOB REST reads for deeper snapshots. Order placement requires the CLOB API with API key + HMAC; reads are public. You must handle tick_size_change events because tick size moves to $0.001 near price extremes. Polymarket’s Relayer sponsors gas, and CTF operations (split/merge/redeem) are needed to mint and settle complete sets when you buy all outcomes. Builders routing orders can use attribution headers and earn builder fees if enrolled in the Builder Program.

Where PolyArb fits and why the code matters

PolyArb is a turn-key arbitrage bot that runs against the exact Polymarket endpoints listed above. For $99/month you get a non-custodial bot with ~40ms latency, Telegram and Discord alerts, and a $7.62 minimum guaranteed edge per trade. That latency and integrated handling of CTF operations reduce slippage and partial-fill complexity. Remember: captures of mathematical edge still carry risks—UMA disputes delaying settlement, partial fills, fee changes, and smart-contract risk. PolyArb automates monitoring and execution, but these platform risks remain.

Run arbitrage code without the infrastructure headache

Try PolyArb for $99/month to get low-latency execution, Telegram and Discord alerts, non-custodial operation, and the $7.62 minimum guaranteed edge per trade.

FAQ

Can I access Polymarket APIs without code?
Yes. Gamma and Data REST endpoints are public for reads. The CLOB REST read endpoints are public; creating or cancelling orders requires API key + HMAC and the trading flow handled by the Relayer.
Do I need pUSD or USDC to trade programmatically?
You need pUSD (Polymarket’s wrapped USDC) to trade. Polymarket sponsors gas via its Relayer, so you only need pUSD for trades and CTF operations.
Is PolyArb compatible with the Builder Program?
PolyArb routes orders through the CLOB and can include builder attribution. The Builder Program tiers and rewards are managed by Polymarket; PolyArb users should follow enrollment steps on Polymarket’s settings if they need direct builder benefits.
