> Official open-source libraries for interacting with Polymarket

Polymarket provides official open-source clients in TypeScript, Python, and Rust. All three support the full CLOB API including market data, order management, and authentication.

## Installation

<CodeGroup>
  ```bash TypeScript theme={null}
  npm install @polymarket/clob-client ethers@5
  ```

  ```bash Python theme={null}
  pip install py-clob-client
  ```

  ```bash Rust theme={null}
  cargo add polymarket-client-sdk
  ```
</CodeGroup>

## Quick Example

<CodeGroup>
  ```typescript TypeScript theme={null}
  import { ClobClient } from "@polymarket/clob-client";

  const client = new ClobClient(
    "https://clob.polymarket.com",
    137,
    signer,
    apiCreds,
  );

  const markets = await client.getMarkets();
  ```

  ```python Python theme={null}
  from py_clob_client.client import ClobClient

  client = ClobClient(
      "https://clob.polymarket.com",
      key=private_key,
      chain_id=137,
      creds=api_creds,
  )

  markets = client.get_markets()
