Python client for the Polymarket CLOB. Full API documentation can be found [here](https://docs.polymarket.com/developers/dev-resources/main).

### Installation

`pip install py-clob-client`

Intended for use with Python 3.9

### Requisites

#### Allowances
Adjusting and setting allowances is only required when using an EOA or a web3 wallet like MetaMask. If you sign in with a Magic link or email login, allowances are automatically configured for you during account creation.

If you are interacting with the API with an EOA or web3/MetaMask wallet then correct token allowances must be set before orders can be placed. 
The following mainnet (Polygon) allowances should be set by the funding (maker) address. For additional documentation please refer to the [API documentation](https://polymarket.github.io/slate-docs/#introduction).

See [this gist](https://gist.github.com/poly-rodr/44313920481de58d5a3f6d1f8226bd5e) for a an example of how to set these allowances for an account using python.

### Usage

```py
from py_clob_client.client import ClobClient
from py_clob_client.clob_types import OrderArgs, OrderType
from py_clob_client.order_builder.constants import BUY

host: str = "https://clob.polymarket.com"
key: str = "" #This is your Private Key. Export from reveal.polymarket.com or from your Web3 Application
chain_id: int = 137 #No need to adjust this
POLYMARKET_PROXY_ADDRESS: str = '' #This is the address you deposit/send USDC to to FUND your Polymarket account.

#Select from the following 3 initialization options to matches your login method, and remove any unused lines so only one client is initialized.


### Initialization of a client using a Polymarket Proxy associated with an Email/Magic account. If you login with your email use this example.
client = ClobClient(host, key=key, chain_id=chain_id, signature_type=1, funder=POLYMARKET_PROXY_ADDRESS)

### Initialization of a client using a Polymarket Proxy associated with a Browser Wallet(Metamask, Coinbase Wallet, etc)
client = ClobClient(host, key=key, chain_id=chain_id, signature_type=2, funder=POLYMARKET_PROXY_ADDRESS)

### Initialization of a client that trades directly from an EOA. 
client = ClobClient(host, key=key, chain_id=chain_id)

## Create and sign a limit order buying 5 tokens for 0.010c each
#Refer to the Markets API documentation to locate a tokenID: https://docs.polymarket.com/developers/gamma-markets-api/get-markets

client.set_api_creds(client.create_or_derive_api_creds()) 

order_args = OrderArgs(
    price=0.01,
    size=5.0,
    side=BUY,
    token_id="", #Token ID you want to purchase goes here. 
)
signed_order = client.create_order(order_args)

## GTC(Good-Till-Cancelled) Order
resp = client.post_order(signed_order, OrderType.GTC)
print(resp)
```
