alpha_vantage_stock

Small service to get data from alpha vantage API.

Invoke this API at: https://9mj1a85khj.execute-api.sa-east-1.amazonaws.com/v1/

Try a front-end example here.

Example input:

{
	"AtivoNome": "GOOGL",
	"DataPreco": "2018-07-04"
}

Example output:

{
	"AtivoNome": "GOOGL",
	"DataPreco": "2018-07-04",
	"Preco": "1116.28000000"
}

The stock price returned as "Preco" is obtained as follows:

1. A call to the Alpha Vantage API with the function TIME_SERIES_DAILY_ADJUSTED is made;
2. The stock value for that desired date is obtained from the "4.close" key. If the desired date is not present on the retrieved data, the day before is considered;
3. The stock value is formatted with 8 decimal places.
