description	Implement Perplexity rate limiting, backoff, and request queuing. Use when handling 429 errors, implementing retry logic, or optimizing API request throughput for Perplexity Sonar. Trigger with phrases like "perplexity rate limit", "perplexity throttling", "perplexity 429", "perplexity retry", "perplexity backoff".

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

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. || error.?.;
      
       (status && status !==  && status < )  error;

       exponentialDelay = config. * .(, attempt);
       jitter = .() * config.;
       delay = .(exponentialDelay + jitter, config.);

      .();
        ( (r, delay));
    }
  }
    ();
}


 result =  (
  perplexity...({
    : ,
    : [{ : , :  }],
  })
);
