Get a smart-account address

POST /api/aa/account

Returns a user's (possibly counterfactual) ERC-4337 smart-account address for a chain, plus whether it is already deployed and the EntryPoint / factory / paymaster in use. owner defaults to the authenticated caller; supply it explicitly to look up another owner. Requires the chain to have smart accounts configured (account_factory + paymaster + a paymaster key).

Authentication

Send your API key in the api-key header.
