wallets is an array of objects. See Create customer wallets for the per-wallet field table (chain, address, balance, network, balanceUnavailable, tokens, tokensUnavailable). An empty list ([]) is a valid answer for a customer with no wallets — it is not a 404.

Errors

503 temporarily_unavailable if balances could not be read transiently — retry shortly. 500 internal_error for a permanent read failure — do not retry automatically.
