Read

To read the Base Account address associated with a given user_id and available on all EVM chains, use the Universal Resolver API. 👇
var myHeaders = new Headers();
myHeaders.append("Authorization", "Bearer {{access_token}}");
myHeaders.append("Content-Type", "application/json");
​
var raw = JSON.stringify({
"userIds": "twitter:elonmusk,email:[email protected],github:torvalds"
});
​
var requestOptions = {
method: 'POST',
headers: myHeaders,
body: raw,
redirect: 'follow'
};
​
fetch("https://paymagicapi.com/v1/resolver", requestOptions)
.then(response => response.text())
.then(result => console.log(result))
.catch(error => console.log('error', error));

Create

Base Account addresses are available instantly with no gas needed and can receive NFTs and tokens. But to sign or submit transactions, a Base Account contract must be deployed to the target EVM chain, which can be done via the create endpoint.

Submit Tx / Sign

Base Accounts can sign messages and submit transactions via the API.
