Disable Authorization for your APIs

You can disable authorization for your APIs, allowing you to create APIs that are accessible to anyone with the URL. You can add authorized=False to REST APIs, Task Queues, Scheduled Jobs, and ASGI apps.

@app.rest_api(authorized=False)
def handler():
    ...

​
Task status included in webhook callbacks

Task status is now included in the header field for all webhook callbacks as x-beam-task-status:

curl -X 'POST' 'https://YOUR-WEBHOOK-URL' -H 'x-beam-task-status: COMPLETE' -H 'beam-task-id: 2171451e-3d8e-4e35-a06d-46f2817569ef'

​
New Examples

​
Adding multiple API routes per app

You can use ASGI apps along with FastAPI to add multiple API routes to a single deployment. For example, you might want an app with two separate routes: one to train a model, and one for running inference.

Endpoint 1

https://[APP-ID].apps.beam.cloud/divide?x=10

Endpoint 2

https://[APP-ID].apps.beam.cloud/square?x=100

from beam import App, Runtime, Image
from fastapi import FastAPI

app = App(
    name="square",
    runtime=Runtime(
        cpu=1,
        memory="1Gi",
        image=Image(
            python_packages=["fastapi"]
        )
    ),
)

api = FastAPI()


@app.asgi(authorized=False)
def handler():
    @api.get("/square")
    def square(x: int):
        return {"square": x**2}

    @api.get("/divide")
    def divide(x: int):
        return {"dividend": x / 2}

    return api
