Clients & SDKs

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

```bash TypeScript theme={null} npm install @polymarket/clob-client-v2 viem ```

pip install py-clob-client-v2

cargo add polymarket_client_sdk_v2 --features clob

Quick Example

```typescript TypeScript theme={null} import { ClobClient } from "@polymarket/clob-client-v2";

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

const markets = await client.getMarkets();

```python Python theme={null}
from py_clob_client_v2 import ClobClient

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

markets = client.get_markets()

use polymarket_client_sdk_v2::clob::{Client, Config};

let client = Client::new("https://clob.polymarket.com", Config::default())?
    .authentication_builder(&signer)
    .authenticate()
    .await?;

let markets = client.markets(None).await?;
