## What it is
A Python client library for the Polymarket Central Limit Order Book (CLOB), enabling programmatic trading on prediction markets via the Polygon blockchain. The repository has been archived and the client is no longer functional; users should migrate to the new unified Polymarket SDK.

## Use cases
- place and cancel orders on Polymarket prediction markets programmatically
- query market data and order book state from Polymarket CLOB API
- sign and submit trades with EOA, Magic email, or proxy wallet signatures
- build automated trading bots for prediction markets
- derive API credentials for authenticated Polymarket endpoints

## When to choose
- you are maintaining a legacy integration that already depends on py-clob-client
- you need reference code for how Polymarket CLOB signing worked historically

## When to avoid
- starting any new Polymarket integration - the client is archived and non-functional
- production trading systems, since the API client no longer works
- you want an actively maintained SDK - use Polymarket's new unified py-sdk instead
