Usage

Configuration (recommended)

Set up your API key and TLS support as ENV variables.

MARKETSTACK_API_KEY="xyz"
MARKETSTACK_TLS_SUPPORT="1"

Create your client

from marketstack.client import Client
import os

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")

Call operations

from marketstack.api.eod import eod
import os

response = eod.sync(
    client=client,
    access_key=os.getenv("MARKETSTACK_API_KEY"),
    symbols="AAPL,AMZN",
    limit=10,
)

All endpoint features are implemented and tested. For examples see the repository's tests/ directory.

from marketstack.models import ErrorCode, ErrorResponse

assert isinstance(response, ErrorResponse)
assert response.error.code == ErrorCode.FUNCTION_ACCESS_RESTRICTED

Map to Pandas dataframe

import pandas as pd

df = pd.DataFrame(map(lambda x: x.__dict__, response.data))
