+# This endpoint should accept:
+# - cashu_token (required): The eCash token to deposit
+# - refund_lnurl (optional): LNURL for refunds (instead of refund_address in validate_bearer_key)
+# - refund_expiry (optional): Expiry timestamp for the key (maps to key_expiry_time in validate_bearer_key)
+# The endpoint should:
+# 1. Create a new wallet/API key from the cashu_token
+# 2. Store refund_lnurl and refund_expiry in the database
+# 3. Return the API key (rstr_...) and balance
+# Note: validate_bearer_key already supports refund_address and key_expiry_time params
