# Perplexity Rate Limits ## Overview Handle Perplexity Sonar API rate limits. Perplexity uses a leaky bucket algorithm: burst capacity is available, with tokens refilling continuously at your assigned rate. Rate limits are based on requests per minute (RPM). ## Rate Limit Tiers | Tier | RPM | Notes | |------|-----|-------| | Free / Starter | 50 | Default for new API keys | | Search API | ~3 req/sec | Per-endpoint limit | | Higher tiers | Contact sales | Custom limits available | Rate limits apply per API key, not per model. Using `sonar-pro` counts against the same RPM as `sonar`. ## Prerequisites - `PERPLEXITY_API_KEY` set - Understanding of HTTP 429 responses ## Instructions ### Step 1: Exponential Backoff with Jitter ```typescript async function withExponentialBackoff<T>( operation: () => Promise<T>, config = { maxRetries: 5, baseDelayMs: 1000, maxDelayMs: 30000, jitterMs: 500 } ): Promise<T> { for (let attempt = 0; attempt <= config.maxRetries; attempt++) { try { return await operation(); } catch (error: any) { if (attempt === config.maxRetries) throw error; const status = error.status || error.response?.status; // Only retry on 429 (rate limit) and 5xx (server errors) if (status && status !== 429 && status < 500) throw error; const exponentialDelay = config.baseDelayMs * Math.pow(2, attempt); const jitter = Math.random() * config.jitterMs; const delay = Math.min(exponentialDelay + jitter, config.maxDe...
