Hello!
Thanks for reaching out. I just tested this both via the sandbox console and JS axios and all seems to be working as intended. Are you still having this issue? Here’s some example code to try with.

const axios = require("axios");

const options = {
    method: 'GET',
    url: 'https://stock-price4.p.rapidapi.com/price/TSLA',
    headers: {
        'X-RapidAPI-Host': 'stock-price4.p.rapidapi.com',
        'X-RapidAPI-Key': 'YOURKEY'
    }
};

axios.request(options).then(function (response) {
    console.log(response.data);
}).catch(function (error) {
    console.error(error);
});
