In at present’s tutorial, we’ll present you tips on how to use the {industry}’s #1 crypto worth API – the Moralis Worth API – to fetch an asset’s real-time and historic worth. We’ll additionally briefly present you tips on how to make batch requests to fetch the costs of a number of belongings concurrently. When you’re wanting to get going, then listed here are three fast examples of the way it works:
Fetch Actual-Time PricesWith a single API name to the getTokenPrice() endpoint, you possibly can seamlessly fetch the real-time worth of an asset: import Moralis from ‘moralis’;
attempt {
await Moralis.begin({
apiKey: “YOUR_API_KEY”
});
const response = await Moralis.EvmApi.token.getTokenPrice({
“chain”: “0x1”,
“deal with”: “0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0”
});
console.log(response.uncooked);
} catch (e) {
console.error(e);
} Get Historic PricesBy specifying the toBlock parameter when calling the getTokenPrice() endpoint, you possibly can effortlessly get the value of an asset at a given cut-off date: import Moralis from ‘moralis’;
attempt {
await Moralis.begin({
apiKey: “YOUR_API_KEY”
});
const response = await Moralis.EvmApi.token.getTokenPrice({
“chain”: “0x1”,
“toBlock”: 18085987,
“deal with”: “0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0”
});
console.log(response.uncooked);
} catch (e) {
console.error(e);
} Make Batch RequestsYou could make batch requests by passing an array of addresses to get the value of a number of tokens in a single response:// Dependencies to put in:
// $ npm set up node-fetch –save
// add “sort”: “module” to bundle.json
import fetch from ‘node-fetch’;
const choices = {
methodology: ‘POST’,
headers: {
settle for: ‘utility/json’,
‘content-type’: ‘utility/json’,
‘X-API-Key’: ‘YOUR_API_KEY’
},
physique: JSON.stringify({
“tokens”: [
{
“token_address”: “0xae7ab96520de3a18e5e111b5eaab095312d7fe84”,
