| ---------------------- | -------- | --------------- |
| **Response Time**      | \< 500ms | > 2s            |
| **Error Rate**         | \< 0.1%  | > 1%            |
| **Availability**       | 99.9%    | \< 99%          |

* Error rates by endpoint
* Transaction success rates
* Token refresh failures

### Infrastructure Monitoring

* Server health
* Network connectivity
* Certificate expiration
* Disk and memory usage

## Alerting

Configure alerts for:

* API errors (4xx, 5xx)
* Latency spikes
* Authentication failures
* Webhook delivery failures
