farcaster-py

farcaster-py is a modern Python SDK for the Farcaster protocol

Full documentation can be found here

Installation

pip install -U farcaster

or install with Poetry:

poetry add farcaster

Usage

This SDK leverages the Warpcast API. Warpcast is one of many Farcaster clients. As more APIs are created and hosted by different clients, these will be added to the SDK.

To use the Warpcast API you need to have a Farcaster account. We will use the mnemonic or private key of the Farcaster custody account (not your main wallet) to connect to the API.

First, save your Farcaster mnemonic or private key to a .env file. Now you can initialize the client, and automatically connect to the Farcaster API!

import os
from farcaster import Warpcast
from dotenv import load_dotenv # can be installed with `pip install python-dotenv`

load_dotenv()

client = Warpcast(mnemonic=os.environ.get("<MNEMONIC_ENV_VAR>"))

print(client.get_healthcheck())

Examples

Get a cast

response = client.get_cast("0x321712dc8eccc5d2be38e38c1ef0c8916c49949a80ffe20ec5752bb23ea4d86f")
print(response.cast.author.username) # "dwr"

Publish a cast

response = client.post_cast(text="Hello world!")
print(response.cast.hash) # "0x...."

Get a user by username

user = client.get_user_by_username("mason")
print(user.username) # "mason"

Get a user's followers using a fid (farcaster ID)

response = client.get_followers(fid=50)
print(response.users) # [user1, user2, user3]

Stream recent casts

for cast in client.stream_casts():
    if cast:
        print(cast.text) # "Hello world!"

Get users who recently joined Farcaster

response = client.get_recent_users()
print(response.users) # [user1, user2, user3]

Get your own user object

user = client.get_me()
print(user.username) # "you"

Recast a cast

response = client.recast("0x....")
print(response.cast.hash) # "0x...."

and many, many more things. The full specification can be found on the Reference page.

Please note that support for Python 3.7 is no longer actively maintained. Python 3.8, 3.9, or 3.10 are recommended.
