如何在每个请求仅支持一个 ID 的 API 端点中获取多个 ID？

Question

I'm using Coingecko API for price data and time (Unix) to output this in a chart, but the endpoint I'm using only supports one ID per request.

document.onreadystatechange = async () => {
  if (document.readyState === "complete") {
    const coin = "bitcoin";
    const currency = "brl";




const response = await fetch(

  `https://api.coingecko.com/api/v3/coins/${coin}/market_chart?vs_currency=${currency}&days=10&interval=hourly
  `
);

const data = await response.json();



const prices = data.prices.map((e) => e[1]);
const date = data.prices.map(i => i[0]);

i need that the function do the same also for solana, cardano, ripple, dash and litecoin

If your API only supports one ID per request, and you need multiple IDs, you're going to need to make multiple requests.

One way to do them in parallel and wait for all to complete before continuing would be

const data = await Promise.all([
    fetch(endpoint1).then(response => response.json()), 
    fetch(endpoint2).then(response => response.json()), 
    fetch(endpoint3).then(response => response.json())
]);
