Perplexity Reliability Patterns

Overview

Production reliability patterns for Perplexity Sonar API. Perplexity performs live web searches per request, making response times inherently variable. The key reliability challenges: search can stall, citations can break, and model tiers have different availability.

Prerequisites

• Perplexity API key configured
• Cache layer (Redis or in-memory)
• Understanding of search latency variability
