A simple Arduino library that retrieves live stock prices from www.robinhood.com in JSON format and processes it for ESP8266. In one example, we demonstrate a whole bunch of stock prices scrolling through a dot-matrix display.
An Arduino library to talk to Robin Hood using non-documented Rest API made for ESP8266. Some unofficial documentaion by @sanko is available at here]
To use in your sketch include these lines.
#include <ESP8266WiFi.h>
#include <RobinhoodAPI.h>
Declare WiFiClientSecure and pass it to RobinhoodAPI.
String fp_robinhood_042018 = "8F C1 46 FB 19 0A 16 FF F7 D1 E6 48 5C 74 54 0E 00 FF 36 A6"; // update with latest fp from https://www.grc.com/fingerprints.htm
WiFiClientSecure sclient;
//RobinhoodAPI rh(sclient); // Declare API with no fingerprint check!
RobinhoodAPI rh(sclient, fp_robinhood_042018); // Declare API with fingerprint check
Using the API to get live stock values.
String stocksybl = "TSLA";
if(rh.getStockQuote(stocksybl)) {
Serial.println(stocksybl);
Serial.printf("Latest Price : %.2f\n", rh.lastTradePrice());
Serial.printf("Percent Change: %.2f%%\n", rh.percentDiff());
}
