Hey @pure.roboot

The error message states “error”: “Insufficient balance. You may need to wrap Ether.”
You can only place buy orders using ERC20 tokens, make sure to have enough wrapped eth.

ah thank you !

but how to know the type of the tocken

ETH is the native currency, WETH is the wrapped ETH that is an ERC20 token

What exactly are you trying to do there?
What command did you run?

making like this : https://moralis-opensea-plugins.on.fleek.co/

on what command (line of code) you get that error?
