Get wallet address information

For a client to request a grant from an authorization server, the client must first verify the validity of the wallet address and get the URL of the wallet’s authorization server.

These code snippets enable an authenticated client to verify a wallet address, get the basic information required to construct a new transaction, and discover the auth server’s URL. Note that unauthenticated clients can also call the OP API to get wallet address information.

Before you begin

We recommend creating a wallet account on Rafiki.Money, a test wallet provider that’s part of the Interledger testnet. Creating an account allows you to test your client against the Open Payments API using an ILP-enabled wallet funded with play money.
