Polymarket

Polymarket

Query Polymarket prediction markets and trade from the terminal.

Setup

Read-only commands work immediately (no install needed).

For trading, order books, and price history, install the Polymarket CLI:

curl -sSL https://raw.githubusercontent.com/Polymarket/polymarket-cli/main/install.sh | sh

For trading, set up a wallet:

python3 {baseDir}/scripts/polymarket.py wallet-setup

Or manually configure ~/.config/polymarket/config.json with your private key. See the CLI docs for details.

⚠️ Safety Notes

• Real money. Trades execute on Polygon with real USDC. Double-check everything.
• All trades require --confirm. Without it, you get a preview only.
• The CLI is experimental. The Polymarket team warns: "Use at your own risk and do not use with large amounts of funds."
• Private key security. Your key is stored in ~/.config/polymarket/config.json. Keep it safe.
• Gas fees. On-chain operations (approvals, splits, redeems) require MATIC for gas.

API

Read-only commands use the public Gamma API (no auth):

• Base URL: https://gamma-api.polymarket.com

Trading commands wrap the official Polymarket CLI (Rust binary).
