}For 429 and transient 5xx, use exponential backoff with jitter (e.g. randomised 100-1500 ms, doubling on repeats). Include an Idempotency-Key header on write-like operations to avoid duplicates.
If you’re consistently seeing 4xx, something in the request likely needs adjusting. If you’re seeing 5xx, it may be our services or an upstream provider. We always include clear messages and a generation_id to help you diagnose fast.
