Step 1
Track success rate, latency percentiles and 429 rates per API and per key.
Step 2
Correlate logs with request IDs returned by the gateway or provider.
Step 3
Alert on sustained error spikes, not single blips, to avoid pager noise.
Step 4
Separate client bugs (4xx) from upstream failures (5xx) in dashboards.
Step 5
Keep PII out of logs — hash or redact identifiers when possible.
