Pre-requisites
To install and use you need:
- A fresh virtual environment
- Python 3.8 or higher
- API keys for the APIs you want to use
To develop you need:
- Poetry 1.5.1 or higher
- ruff 0.0.256
- mypy 1.4.1
- black
Installation
To install the SDK in the virtual environment from the repo root run:
pip install ./openbb_sdk
This will install the SDK and all the dependencies into the site-packages folder of the virtual environment.
API keys
To connect to APIs you need to provide the API keys. Here 3 options how you can provide them:
- From local file
- At runtime
- From OpenBB Hub
From local file
You can specify the keys from the ~/.openbb_sdk/user_settings.json file.
Create this file with the following template:
{
"credentials": {
"fmp_api_key": "REPLACE_ME",
"polygon_api_key": "REPLACE_ME",
"benzinga_api_key": "REPLACE_ME",
"fred_api_key": "REPLACE_ME"
}
}
Then add your API keys there and it should work.
From runtime
You can also specify the keys at runtime:
from openbb import obb
obb.settings.credentials.fmp_api_key = "REPLACE_ME"
obb.settings.credentials.polygon_api_key = "REPLACE_ME"
From OpenBB Hub
You can also load your the keys from the OpenBB Hub.
from openbb import obb
openbb.account.login(username="REPLACE_ME", password="REPLACE_ME")
Python Usage
Import and basic usage:
from openbb import obb
aapl = obb.stocks.load(symbol="AAPL", start_date="2020-01-01", provider="fmp")
df = aapl.to_dataframe()
df.head()
API Usage
Launch the API with:
uvicorn openbb_core.api.rest_api:app --host 0.0.0.0 --port 8000 --reload
Navigate to http://0.0.0.0:8000/docs to see the swagger API documentation.
Authorize with the developer credentials: openbb/openbb
Docker
You can use the API through docker.
To build the image from the repo root run:
docker build -f build/docker/api.dockerfile -t openbb-sdk:latest .
To run the image:
docker run --rm -p8000:8000 -v ~/.openbb_sdk:/root/.openbb_sdk openbb-sdk:latest
This will mount the local ~/.openbb_sdk folder into the docker container so you can use the API keys from there and it will expose the API on port 8000.
Development
From the root of the OpenBB Terminal repo run:
poetry install -C ./openbb_sdk
When developing a specific extension cd into the extension folder and run:
pip install -U -e .
While we're still developing it is required to create the static python interface:
import openbb
openbb._rebuild_python_interface()
exit()
Right now you need to do this before the first launch and every time you install or uninstall a new extension.
