Step 4 – Write a Script Calling the Optimism API
On this part, we’ll present you the right way to name the varied endpoints of Moralis’ Optimism API. To take action, we’ll write a brief script for fetching the native stability of a pockets with the getNativeBalance() endpoint. Nonetheless, that is merely an Optimism API instance, and you may comply with roughly the identical process for any of our endpoints!
Earlier than persevering with, be sure to have the next prepared:
From right here, arrange a brand new folder in your IDE and initialize a brand new undertaking by working the next command in a brand new terminal:
npm init
Subsequent, set up the Moralis SDK with the next terminal command:
npm set up moralis @moralisweb3/common-evm-utils
You then have to open your ”bundle.json” file and add ”sort”: ”module” to the checklist:
Subsequent, create a brand new ”index.js” file and add the next code:
import Moralis from ‘moralis’;
strive {
await Moralis.begin({
apiKey: “YOUR_API_KEY”
});
const response = await Moralis.EvmApi.stability.getNativeBalance({
“chain”: “0xa”,
“deal with”: “0xCBA6a2397b322CF1389f6d1adc05F75F36B20116”
});
console.log(response.uncooked);
} catch (e) {
console.error(e);
}
From right here, you now have to configure the code barely by changing YOUR_API_KEY together with your Moralis API key, together with modifying the chain and deal with parameters to suit your question.
That’s it; you’re now able to run the script!
Step 5 – Run the Code
To execute the script, open a brand new terminal and run the command under in your undertaking’s root folder:
node index.js
In return, you’ll get a response that appears one thing like this:
{
“stability”: “57881481011270850225”
}
That’s it! You now know the right way to fetch all the pieces from pockets balances to token costs utilizing Moralis’ Optimism API suite. Consequently, you’re now outfitted with the abilities to fetch on-chain information and might begin to construct your personal dapps on Optimism!
