Pre-requisites

To install and use the SDK you need:

• A fresh virtual environment
• Python 3.8 or higher
• API keys for the APIs you want to use

For development you need:

• Poetry 1.5.1 or higher
• ruff 0.0.256
• mypy 1.4.1
• black

Installation

To install the SDK in a virtual environment from the repo root run:

pip install ./openbb_sdk

This will install the SDK and all its dependencies into the site-packages directory of the virtual environment.

API keys

To use your API keys you need to configure them. Here are the 3 options on how to do it:

1. From local file
2. At runtime
3. From OpenBB Hub

1. From local file

You can specify the keys in the ~/.openbb_sdk/user_settings.json file.

Create this file using the following template and replace the values with your keys:

{
  "credentials": {
    "fmp_api_key": "REPLACE_ME",
    "polygon_api_key": "REPLACE_ME",
    "benzinga_api_key": "REPLACE_ME",
    "fred_api_key": "REPLACE_ME"
  }
}

2. From runtime

You can also specify your keys at runtime:

from openbb import obb
obb.user.credentials.fmp_api_key = "REPLACE_ME"
obb.user.credentials.polygon_api_key = "REPLACE_ME"

3. 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("AAPL")
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 this newly-built image:

docker run --rm -p8000:8000 -v ~/.openbb_sdk:/root/.openbb_sdk openbb-sdk:latest

This will mount the local ~/.openbb_sdk directory 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 directory and run:

pip install -U -e .

While we're still developing, it is often required to reinstall extensions:

python -c "import openbb; openbb.build()"

You need to do this every time you install or uninstall a new extension or to reinstall all extensions.

Import time

We aim to have a short import time. To measure that we use tuna.

• https://pypi.org/project/tuna/

To visualize the import time breakdown by module, run the following commands from openbb_sdk directory:

pip install tuna
python -X importtime openbb/__init__.py 2> import.log
tuna import.log
