โ ๏ธ Under construction. Until the 1.0.0 release, I am not going to care about backward compatibility between versions.
Code snippet:
from atproto import Client, models
def main():
client = Client()
profile = client.login('my-handle', 'my-password')
print('Welcome,', profile.display_name)
response = client.send_post(text='Hello World from Python!')
client.like(models.create_strong_ref(response))
if __name__ == '__main__':
main()
Code snippet of async version
import asyncio
from atproto import AsyncClient, models
async def main():
client = AsyncClient()
profile = await client.login('my-handle', 'my-password')
print('Welcome,', profile.display_name)
response = await client.send_post(text='Hello World from Python!')
await client.like(models.create_strong_ref(response))
if __name__ == '__main__':
# use run() for a higher Python version
asyncio.get_event_loop().run_until_complete(main())
๐ฟ Example project with custom feed generator
๐ฅ Firehose data streaming is available!
This SDK attempts to implement everything that provides ATProto. Due to the unstable state of the protocol (it grows and changes fast) and a bit of outdated documentation, only the client side is supported for now. There is support for Lexicon Schemes, XRPC clients, and Firehose. All models, queries, and procedures are generated automatically. The main focus is on the lexicons of atproto.com and bsky.app, but it doesn't have a vendor lock on it. Feel free to use the code generator for your own lexicon schemes. SDK also provides utilities to work with CID, NSID, AT URI Schemes, DAG-CBOR, CAR files.
- Python 3.7.1 or higher.
- Access to Bsky if you don't have an own server.
pip3 install -U atproto
First of all, you need to create the instance of the XRPC Client. To do so, you have two major options: asynchronous, and synchronous. The difference only in import and how you call the methods. If you are not familiar with async, use sync instead.
For sync:
from atproto import Client
client = Client()
# By default, it uses the server of bsky.app. To change this behavior, pass the base api URL to constructor
# Client('https://my.awesome.server/xrpc')
For async:
from atproto import AsyncClient
client = AsyncClient()
# By default, it uses the server of bsky.app. To change this behavior, pass the base api URL to constructor
# AsyncClient('https://my.awesome.server/xrpc')
In the snippets below, only the sync version will be presented.
Right after the creation of the Client instance, you probably want to access the full API and perform actions by profile. To achieve this, you should log in to the network using your handle and password. The password could be app-specific.
from atproto import Client
client = Client()
client.login('my-username', 'my-password')
You are awesome! Now you feel to pick any high-level method that you want and perform it!
Code to send post:
from atproto import Client
client = Client()
client.login('my-username', 'my-password')
client.send_post(text='Hello World!')

You can get help in several ways:
- Report bugs, request new features by creating an issue.
- Ask questions by starting a discussion.
- Ask questions in Discord server.
I'll be honest. The high-level Client that was shown in the "Quick Start" section is not a real ATProto API. This is syntax sugar built upon the real XRPC methods! The high-level methods are not cover the full need of developers. To be able to do anything that you want, you should know to work with low-level API. Let's dive into it!
The basics:
- Namespaces โ classes that group sub-namespaces and the XRPC queries and procedures. Built upon NSID ATProto semantic.
- Model โ dataclasses for input, output, and params of the methods from namespaces. Models describe Record and all other types in the Lexicon Schemes.
The client contains references to the root of all namespaces. It's com
and app
for now.
from atproto import Client
Client().com
Client().app
To dive deeper, you can navigate using hints from your IDE. Thanks to well-type hinted SDK, it's much easier.
from atproto import Client
Client().com.atproto.server.create_session(...)
Client().com.atproto.sync.get_blob(...)
Client().app.bsky.feed.get_likes(...)
Client().app.bsky.graph.get_follows(...)
The endpoint of the path is always the method that you want to call. The method presents a query or procedure in XRPC. You should not care about it much. The only thing you need to know is that the procedures required data objects. Queries could be called with or without params.
To deal with methods, we need to deal with models! Models are available in the models
module and have NSID-based aliases. Let's take a look at it.
from atproto import models
models.ComAtprotoIdentityResolveHandle
models.AppBskyFeedPost
models.AppBskyActorGetProfile
# 90+ more...
The model classes in the "models" aliases could be:
- Data model
- Params model
- Response model
- Record model
- Type model
The only thing you need to know is how to create instances of models. Not with all models, you will work as model-creator. For example, SDK will create Response models for you.
There are a few ways how to create the instance of a model:
- Dict-based
- Class-based
The instances of data and params models should be passed as arguments to the methods that were described above.
Dict-based:
from atproto import Client
client = Client()
client.login('my-username', 'my-password')
# The params model will be created automatically internally for you!
print(client.com.atproto.identity.resolve_handle({'handle': 'marshal.dev'}))
Class-based:
from atproto import Client, models
client = Client()
client.login('my-username', 'my-password')
params = models.ComAtprotoIdentityResolveHandle.Params(handle='marshal.dev')
print(client.com.atproto.identity.resolve_handle(params))
Tip: look at typehint of the method to figure out the name and the path to the input/data model!
Pro Tip: use IDE autocompletion to find necessary models! Just start typing the method name right after the dot (models.{type method name in camel case
).
Models could be nested as hell. Be ready for it!
This is how we can send a post with the image using low-level XRPC Client:
from atproto import Client, models
client = Client()
client.login('my-username', 'my-password')
with open('cat.jpg', 'rb') as f:
img_data = f.read()
upload = client.com.atproto.repo.upload_blob(img_data)
images = [models.AppBskyEmbedImages.Image(alt='Img alt', image=upload.blob)]
embed = models.AppBskyEmbedImages.Main(images=images)
client.com.atproto.repo.create_record(
models.ComAtprotoRepoCreateRecord.Data(
repo=client.me.did,
collection=models.ids.AppBskyFeedPost,
record=models.AppBskyFeedPost.Main(
created_at=client.get_current_time_iso(), text='Text of the post', embed=embed
),
)
)
I hope you are not scared. May the Force be with you. Good luck!
Things that a want to do soon:
- Provide autogenerated Record Namespaces with more high-level work with basic operations upon records (CRUD + list records)
