Fixing it would mean editing `client.py` the same way (`str(r[\"amount\"])`) \u2014 outside the scope you gave me and not needed for `test_refunds.py`.\n\nWant me to apply the same string-serialization fix to `client.py` so `test_billing.py` passes too?"}], "stop_reason": null, "stop_sequence": null, "stop_details": null, "usage": {"input_tokens": 2, "cache_creation_input_tokens": 1031, "cache_read_input_tokens": 35145, "cache_creation": {"ephemeral_5m_input_tokens": 0, "ephemeral_1h_input_tokens": 1031}, "output_tokens": 2, "service_tier": "standard", "inference_geo": "not_available"}, "diagnostics": null, "context_management": null}
