Overview
This guide covers essential best practices for using the Perplexity SDKs in production environments. Following these practices will help you build robust, secure, and efficient applications.Security Best Practices
Environment Variables
Always store API keys securely using environment variables:Use environment variables
Store API keys in environment variables, never in source code.
import os
from perplexity import Perplexity
# Good: Use environment variables
client = Perplexity(
api_key=os.environ.get("PERPLEXITY_API_KEY")
)
# Bad: Never hardcode API keys
# client = Perplexity(api_key="pplx-abc123...") # DON'T DO THIS
import Perplexity from '@perplexity-ai/perplexity_ai';
// Good: Use environment variables
const client = new Perplexity({
apiKey: process.env.PERPLEXITY_API_KEY
});
// Bad: Never hardcode API keys
// const client = new Perplexity({
// apiKey: "pplx-abc123..." // DON'T DO THIS
// });
Never commit API keys to version control. Use .env files locally and secure environment variable management in production.
Use .env files for local development
Create a
.env file for local development (add it to .gitignore):cat > .env << 'EOF'
PERPLEXITY_API_KEY=your_api_key_here
PERPLEXITY_MAX_RETRIES=3
PERPLEXITY_TIMEOUT=30000
EOF
from dotenv import load_dotenv
import os
from perplexity import Perplexity
# Load environment variables from .env file
load_dotenv()
client = Perplexity(
api_key=os.getenv("PERPLEXITY_API_KEY"),
max_retries=int(os.getenv("PERPLEXITY_MAX_RETRIES", "3"))
)
import dotenv from 'dotenv';
import Perplexity from '@perplexity-ai/perplexity_ai';
// Load environment variables from .env file
dotenv.config();
const client = new Perplexity({
apiKey: process.env.PERPLEXITY_API_KEY,
maxRetries: parseInt(process.env.PERPLEXITY_MAX_RETRIES || '3')
});
Validate environment variables
Check for required environment variables at startup.
import os
import sys
from perplexity import Perplexity
def create_client():
api_key = os.getenv("PERPLEXITY_API_KEY")
if not api_key:
print("Error: PERPLEXITY_API_KEY environment variable is required")
sys.exit(1)
return Perplexity(api_key=api_key)
client = create_client()
import Perplexity from '@perplexity-ai/perplexity_ai';
function createClient(): Perplexity {
const apiKey = process.env.PERPLEXITY_API_KEY;
if (!apiKey) {
console.error("Error: PERPLEXITY_API_KEY environment variable is required");
process.exit(1);
}
return new Perplexity({ apiKey });
}
const client = createClient();
API Key Rotation
Implement secure API key rotation:import os
import logging
from perplexity import Perplexity
from typing import Optional
class SecurePerplexityClient:
def __init__(self, primary_key: Optional[str] = None, fallback_key: Optional[str] = None):
self.primary_key = primary_key or os.getenv("PERPLEXITY_API_KEY")
self.fallback_key = fallback_key or os.getenv("PERPLEXITY_API_KEY_FALLBACK")
self.current_client = Perplexity(api_key=self.primary_key)
self.logger = logging.getLogger(__name__)
def _switch_to_fallback(self):
"""Switch to fallback API key if available"""
if self.fallback_key:
self.logger.warning("Switching to fallback API key")
self.current_client = Perplexity(api_key=self.fallback_key)
return True
return False
def search(self, query: str, **kwargs):
try:
return self.current_client.search.create(query=query, **kwargs)
except Exception as e:
if "authentication" in str(e).lower() and self._switch_to_fallback():
return self.current_client.search.create(query=query, **kwargs)
raise e
# Usage
client = SecurePerplexityClient()
import Perplexity from '@perplexity-ai/perplexity_ai';
class SecurePerplexityClient {
private primaryKey: string;
private fallbackKey?: string;
private currentClient: Perplexity;
constructor(primaryKey?: string, fallbackKey?: string) {
this.primaryKey = primaryKey || process.env.PERPLEXITY_API_KEY!;
this.fallbackKey = fallbackKey || process.env.PERPLEXITY_API_KEY_FALLBACK;
this.currentClient = new Perplexity({ apiKey: this.primaryKey });
}
private switchToFallback(): boolean {
if (this.fallbackKey) {
console.warn("Switching to fallback API key");
this.currentClient = new Perplexity({ apiKey: this.fallbackKey });
return true;
}
return false;
}
async search(query: string, options?: any) {
try {
return await this.currentClient.search.create({ query, ...options });
} catch (error: any) {
if (error.message.toLowerCase().includes('authentication') && this.switchToFallback()) {
return await this.currentClient.search.create({ query, ...options });
}
throw error;
}
}
}
// Usage
const client = new SecurePerplexityClient();
Rate Limiting and Efficiency
Intelligent Rate Limiting
Implement exponential backoff with jitter:import time
import random
import asyncio
from typing import TypeVar, Callable, Any
import perplexity
from perplexity import Perplexity
T = TypeVar('T')
class RateLimitedClient:
def __init__(self, client: Perplexity, max_retries: int = 5):
self.client = client
self.max_retries = max_retries
def _calculate_delay(self, attempt: int) -> float:
"""Calculate delay with exponential backoff and jitter"""
base_delay = 2 ** attempt
jitter = random.uniform(0.1, 0.5)
return min(base_delay + jitter, 60.0) # Cap at 60 seconds
def with_retry(self, func: Callable[[], T]) -> T:
"""Execute function with intelligent retry logic"""
last_exception = None
for attempt in range(self.max_retries):
try:
return func()
except perplexity.RateLimitError as e:
last_exception = e
if attempt < self.max_retries - 1:
delay = self._calculate_delay(attempt)
print(f"Rate limited. Retrying in {delay:.2f}s (attempt {attempt + 1})")
time.sleep(delay)
continue
raise e
except perplexity.APIConnectionError as e:
last_exception = e
if attempt < self.max_retries - 1:
delay = min(2 ** attempt, 10.0) # Shorter delay for connection errors
print(f"Connection error. Retrying in {delay:.2f}s")
time.sleep(delay)
continue
raise e
raise last_exception
def search(self, query: str, **kwargs):
return self.with_retry(
lambda: self.client.search.create(query=query, **kwargs)
)
# Usage
client = RateLimitedClient(Perplexity())
result = client.search("artificial intelligence")
import Perplexity from '@perplexity-ai/perplexity_ai';
class RateLimitedClient {
private client: Perplexity;
private maxRetries: number;
constructor(client: Perplexity, maxRetries: number = 5) {
this.client = client;
this.maxRetries = maxRetries;
}
private calculateDelay(attempt: number): number {
const baseDelay = 2 ** attempt * 1000; // Convert to milliseconds
const jitter = Math.random() * 500; // 0-500ms jitter
return Math.min(baseDelay + jitter, 60000); // Cap at 60 seconds
}
async withRetry<T>(func: () => Promise<T>): Promise<T> {
let lastError: any;
for (let attempt = 0; attempt < this.maxRetries; attempt++) {
try {
return await func();
} catch (error: any) {
lastError = error;
if (error.constructor.name === 'RateLimitError') {
if (attempt < this.maxRetries - 1) {
const delay = this.calculateDelay(attempt);
console.log(`Rate limited. Retrying in ${delay}ms (attempt ${attempt + 1})`);
await new Promise(resolve => setTimeout(resolve, delay));
continue;
}
} else if (error.constructor.name === 'APIConnectionError') {
if (attempt < this.maxRetries - 1) {
const delay = Math.min(2 ** attempt * 1000, 10000);
console.log(`Connection error. Retrying in ${delay}ms`);
await new Promise(resolve => setTimeout(resolve, delay));
continue;
}
}
throw error;
}
}
throw lastError;
}
async search(query: string, options?: any) {
return this.withRetry(() =>
this.client.search.create({ query, ...options })
);
}
}
// Usage
const client = new RateLimitedClient(new Perplexity());
const result = await client.search("artificial intelligence");
Request Batching
Efficiently batch multiple requests:import asyncio
from typing import Callable, Awaitable, List, TypeVar, Generic
from perplexity import AsyncPerplexity, DefaultAioHttpClient
T = TypeVar('T')
class BatchProcessor(Generic[T]):
def __init__(self, batch_size: int = 5, delay_between_batches: float = 1.0):
self.batch_size = batch_size
self.delay_between_batches = delay_between_batches
async def process_batch(
self,
items: List[str],
process_func: Callable[[str], Awaitable[T]]
) -> List[T]:
"""Process items in batches with rate limiting"""
results = []
for i in range(0, len(items), self.batch_size):
batch = items[i:i + self.batch_size]
# Process batch concurrently
tasks = [process_func(item) for item in batch]
batch_results = await asyncio.gather(*tasks, return_exceptions=True)
# Filter out exceptions and collect results
for result in batch_results:
if not isinstance(result, Exception):
results.append(result)
# Delay between batches
if i + self.batch_size < len(items):
await asyncio.sleep(self.delay_between_batches)
return results
# Usage
async def main():
processor = BatchProcessor(batch_size=3, delay_between_batches=0.5)
async with AsyncPerplexity(
http_client=DefaultAioHttpClient()
) as client:
async def search_query(query: str):
return await client.search.create(query=query)
queries = ["AI", "ML", "DL", "NLP", "CV"]
results = await processor.process_batch(queries, search_query)
print(f"Processed {len(results)} successful queries")
asyncio.run(main())
import Perplexity from '@perplexity-ai/perplexity_ai';
class BatchProcessor<T> {
constructor(
private batchSize: number = 5,
private delayBetweenBatches: number = 1000
) {}
async processBatch<R>(
items: T[],
processFunc: (item: T) => Promise<R>
): Promise<R[]> {
const results: R[] = [];
for (let i = 0; i < items.length; i += this.batchSize) {
const batch = items.slice(i, i + this.batchSize);
// Process batch concurrently
const tasks = batch.map(item =>
processFunc(item).catch(error => error)
);
const batchResults = await Promise.all(tasks);
// Filter out exceptions and collect results
for (const result of batchResults) {
if (!(result instanceof Error)) {
results.push(result);
}
}
// Delay between batches
if (i + this.batchSize < items.length) {
await new Promise(resolve =>
setTimeout(resolve, this.delayBetweenBatches)
);
}
}
return results;

}
// Usage
async function main() {
const processor = new BatchProcessor<string>(3, 500);
const client = new Perplexity();
const searchQuery = (query: string) =>
client.search.create({ query });
const queries = ["AI", "ML", "DL", "NLP", "CV"];
const results = await processor.processBatch(queries, searchQuery);
console.log(`Processed ${results.length} successful queries`);

main();
Production Configuration

Testing Best Practices
Unit Testing with Mocking
Create testable code with proper mocking:import unittest

)
self.mock_client.search.create.return_value = mock_response
# Test your application logic
result = self.mock_client.search.create(query="Perplexity Search API rate limit and retry handling example")
self.assertEqual(result.id, "search_123")
self.assertEqual(len(result.results), 1)

jest.spyOn(mockClient.search, 'create').mockRejectedValue(rateLimitError);
await expect(mockClient.search.create({ query: "Perplexity Search API Python SDK quickstart example" })).rejects.toThrow('Rate limited');

Obtain an API key from Perplexity.\n2. You have three options for managing your API key:\nClick here to view the API key configuration options - **Setting it as an environment variable on your device (recommended for everyday use)**\n- Navigate to your terminal.\n- Add your API key like so:\n```\nexport PERPLEXITY_API_KEY=your_api_key\n```\nThis method allows the API key to be loaded automatically when using the wrapper or CLI.\n- **Using an .env file (recommended for development):**\n- Install python-dotenv if you haven't already: `pip install python-dotenv`.\n- Create a .env file in the project's root directory.\n- Add your API key to the .env file like so:\n```\nPERPLEXITY_API_KEY=your_api_key\n```\nThis method allows the API key to be loaded automatically when using the wrapper or CLI, assuming you have python-dotenv installed and set up correctly.\n- **Direct Input:**\n- If you prefer not to use a `.env` file, you can directly pass your API key as an argument to the CLI or the wrapper functions.\n***CLI** *\n```\n--api_key \"your_api_key\"\n```\n***Wrapper** *\n```\napi_key=\"your_api_key\"\n```\n...\nThe Perplexity AI Toolkit can be used in two different modes: `Chat`, and `Search`.\n...\nChat mode is intended for chatting with an AI model (similar to a chatbot) or building conversational applications.\n#### Example Usage\n***CLI** *\n```\npython cli.py --chat\n```\n***Wrapper** *\n```\nfrom perplexity import Chat\nChat().run()\n```\n> An executable version of this example can be found here.\n(*You must move this file to the root folder before running the program.*)\n## Search Mode\nSearch mode is intended for searching online (in real-time) for a single query as perplexity does not support multi-turn conversations with their online models.\n#### Example Usage\n***CLI** *\n```\npython cli.py --search --query \"What is today's date?\"\n```\n***Wrapper** *\n```\nfrom perplexity import Search\nSearch().run(query=\"What is today's date?\")\n```\n> An executable version of this example can be found here.\n(*You must move this file to the root folder before running the program.*)\n*Search mode is limited to 'online' models, such as `llama-3.1-sonar-small-128k-online`, `llama-3.1-sonar-large-128k-online` and `llama-3.1-sonar-huge-128k-online`.*\n...\nA lightweight Python API wrapper and CLI for Perplexity’s Sonar language models.",
