alphavantage-api-client

I use these functions in my AWS Step function statemachines. Each method for querying stock data has 2 params ( event,context). This will support AWS lambda functions, but also allow you to use it any way your want!

At present alphavantage isn't great at Delineating failed messages (has reached limit, error or invalid symbol). This client interprets the response and injects two fields into your response:

1. success (true/false) flag into your response. You can log response into splunk or cloudwatch and know when something fails
2. limit_reached (true/false) flag into your response. You can know the difference between an error and reaching limit so you can pause processing until you api key is allowed to make more requests

install from pip

pip install alphavantage_api_client

Sample Usage Specifying Api Key in Client Builder

from alphavantage_api_client import AlphavantageClient
import json

event = {
        "symbol":"TSLA"
}
result = {}
client = AlphavantageClient().with_api_key('[you key here]')
result['overview'] = client.get_company_overview(event)
result['latest_stock_price'] = client.get_latest_stock_price(event)
result['stock_price'] = client.get_stock_price(event)
result['earnings'] = client.get_earnings(event)
result['latest_earnings'] = client.get_latest_earnings(event)
result['cash_flow'] = client.get_cash_flow(event)
result['latest_cash_flow'] = client.get_latest_cash_flow(event)
result['income_statement'] = client.get_income_statement_for_symbol(event)
result['latest_income_statement'] = client.get_latest_income_statement_for_symbol(event)
print(json.dumps(result))

Sample Usage Specifying Api Key in request event

from alphavantage_api_client import AlphavantageClient
import json

event = {
        "symbol":"TSLA",
        "api_key":"[your api key here]"
}
result = {}
client = AlphavantageClient()
result['overview'] = client.get_company_overview(event)
result['latest_stock_price'] = client.get_latest_stock_price(event)
result['stock_price'] = client.get_stock_price(event)
result['earnings'] = client.get_earnings(event)
result['latest_earnings'] = client.get_latest_earnings(event)
result['cash_flow'] = client.get_cash_flow(event)
result['latest_cash_flow'] = client.get_latest_cash_flow(event)
result['income_statement'] = client.get_income_statement_for_symbol(event)
result['latest_income_statement'] = client.get_latest_income_statement_for_symbol(event)
print(json.dumps(result))

Sample Usage Specifying Api Key in ini file

On mac/linux based machines run the following command BUT use your own API KEY

echo -e "[access]\napi_key=[your key here]" > ~/.alphavantage

Now try the below

from alphavantage_api_client import AlphavantageClient
import json 

event = {
        "symbol":"TSLA"
}
result = {}
client = AlphavantageClient()
result['overview'] = client.get_company_overview(event)
result['latest_stock_price'] = client.get_latest_stock_price(event)
result['stock_price'] = client.get_stock_price(event)
result['earnings'] = client.get_earnings(event)
result['latest_earnings'] = client.get_latest_earnings(event)
result['cash_flow'] = client.get_cash_flow(event)
result['latest_cash_flow'] = client.get_latest_cash_flow(event)
result['income_statement'] = client.get_income_statement_for_symbol(event)
result['latest_income_statement'] = client.get_latest_income_statement_for_symbol(event)
print(json.dumps(result))

Sample Usage Specifying Api Key in environment variable

On mac/linux based machines run the following command BUT use your own API KEY

export ALPHAVANTAGE_API_KEY=[your key here]

Now try the below

from alphavantage_api_client import AlphavantageClient
import json

event = {
        "symbol":"TSLA"
}
result = {}
client = AlphavantageClient()
result['overview'] = client.get_company_overview(event)
result['latest_stock_price'] = client.get_latest_stock_price(event)
result['stock_price'] = client.get_stock_price(event)
result['earnings'] = client.get_earnings(event)
result['latest_earnings'] = client.get_latest_earnings(event)
result['cash_flow'] = client.get_cash_flow(event)
result['latest_cash_flow'] = client.get_latest_cash_flow(event)
result['income_statement'] = client.get_income_statement_for_symbol(event)
result['latest_income_statement'] = client.get_latest_income_statement_for_symbol(event)
print(json.dumps(result))

Get any data from alphavantage using get_data_from_alpha_vantage(...)

Get Economic indicators
