## Overview

The OpenBB Platform provides a convenient way to access raw financial data from multiple data providers. The package comes with a ready to use REST API - this allows developers from any language to easily create applications on top of OpenBB Platform.

## Installation

The command below provides access to the core functionalities behind the OpenBB Platform.

```bash
pip install openbb
```

This will install the following data providers:

>>> output = obb.equity.price.historical("AAPL")
>>> df = output.to_dataframe()
>>> df.head()

## API keys

To fully leverage the OpenBB Platform you need to get some API keys to connect with data providers. Here are the 3 options on where to set them:

1. OpenBB Hub
2. Runtime
3. Local file

### 1. OpenBB Hub

Set your keys at [OpenBB Hub](https://my.openbb.co/app/sdk/api-keys) and get your personal access token from https://my.openbb.co/app/sdk/pat to connect with your account.

```python
>>> from openbb import obb
>>> openbb.account.login(pat="OPENBB_PAT")

>>> # Persist changes in OpenBB Hub
>>> obb.account.save()
```

### 2. Runtime

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

>>> # Persist changes in ~/.openbb_platform/user_settings.json
>>> obb.account.save()
```

### 3. Local file

You can specify the keys directly in the `~/.openbb_platform/user_settings.json` file.

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

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

## REST API

The OpenBB Platform comes with a ready to use REST API built with FastAPI. Start the application using this command:

```bash
uvicorn openbb_core.api.rest_api:app --host 0.0.0.0 --port 8000 --reload
```

Check `openbb-core` [README](https://pypi.org/project/openbb-core/) for additional info.
