# marketstack-python
Inofficial Python OpenAPI implementation of the [marketstack API](https://marketstack.com/documentation) based on the [marketstack OpenAPI spec](https://github.com/mreiche/marketstack-openapi).
## Usage
### Configuration (recommended)
Set up your API key and TLS support as ENV variables.
```shell
MARKETSTACK_API_KEY="xyz"
MARKETSTACK_TLS_SUPPORT="1"
```
### Create your client
```python
from marketstack.client import Client
import os
def create_client() -> tuple[Client, str]:
access_key = os.getenv("MARKETSTACK_API_KEY")
assert access_key is not None and len(access_key) > 0, "Environment variable MARKETSTACK_API_KEY is not defined"
tls_support = os.getenv("MARKETSTACK_TLS_SUPPORT")
protocol = "https" if tls_support == "1" else "http"
client = Client(base_url=f"{protocol}://api.marketstack.com/v1")
return client, access_key
```
### Call operations
```python
from marketstack.api.eod import eod
client, access_key = create_client()
response = eod.sync(
client=client,
access_key=access_key,
symbols="AAPL,AMZN",
limit=10,
)
```
All endpoint features are implemented and tested. For examples see the repository's `tests/` directory.
### Multiple asynchronous calls
```python
import asyncio
from typing import List
from marketstack.api.intraday import intraday_latest
from marketstack.api.exchanges import exchanges
from marketstack.models import PagedResponseListmodelsIntervalPrice, PagedResponseListmodelsExchange
async def load_async(symbols: List[str]):
client, access_key = create_client()
prices_call = intraday_latest.asyncio(access_key=access_key, client=client, symbols=",".join(symbols))
exchanges_call = exchanges.asyncio(access_key=access_key, client=client)
# Type hints for future results
prices_response: PagedResponseListmodelsIntervalPrice
exchanges_response: PagedResponseListmodelsExchange
prices_response, exchanges_response = await asyncio.gather(prices_call, exchanges_call)
```
### Error handling
```python
from marketstack.models import ErrorCode, ErrorResponse
if isinstance(response, ErrorResponse):
assert response.error.code == ErrorCode.FUNCTION_ACCESS_RESTRICTED
```
### Map to Pandas dataframe
```python
import pandas as pd
df = pd.DataFrame(map(lambda x: x.__dict__, response.data))
```
## Developers area
### Generate the client
1. Install the OpenAPI client generator
```shell
pip install openapi-python-client
```
2. Regenerate the client
```shell
./regenerate.sh
```
### Run the tests
1. Setup your marketstack API key in `tests/test.env`
2. Run the tests via *pytest*
```shell
PYTHONPATH="." pytest --cov=marketstack tests/
```
### Release update
1. Update version in `setup.py`
2. Package library
```shell
python setup.py sdist
```
3. Publish library
```shell
twine upload dist/marketstack-[version].tar.gz
```
