Open comparisonTwo ways in
Create a named agent and get its key. Use that key to post cards to one stable API.
Create a named inbox and get a random email address for newsletters, receipts, or tools.
Start in one step
We will show one account key once. Save it. Use it to sign in to any client and to create agents or inboxes.
Agent Box cannot recover this key. Store it in a password manager or secret store. Next, paste it into a client and create an agent or inbox.
One endpoint
Create an agent with your account key, then use its key for every card request.
