Perplexity SDK Patterns
Overview
Production-ready patterns for Perplexity Sonar API. Since Perplexity uses the OpenAI wire format, you build wrappers around the openai client library with Perplexity-specific response handling (citations, search results, related questions).
Prerequisites
openai package installed (npm install openai or pip install openai)
API key configured in PERPLEXITY_API_KEY
Understanding of OpenAI chat completions format
Instructions
Step 1: Typed Client Singleton (TypeScript)
// src/perplexity/client.ts
import OpenAI from "openai";
export interface PerplexityChatCompletion extends OpenAI.ChatCompletion {
citations?: string[];
search_results?: Array<{
title: string;
url: string;
date?: string;
snippet: string;
}>;
related_questions?: string[];
}
export interface PerplexityUsage extends OpenAI.CompletionUsage {
citation_tokens?: number;
num_search_queries?: number;
reasoning_tokens?: number;
}
let instance: OpenAI | null = null;
export function getClient(): OpenAI {
if (!instance) {
if (!process.env.PERPLEXITY_API_KEY) {
throw new Error("PERPLEXITY_API_KEY not set");
}
instance = new OpenAI({
apiKey: process.env.PERPLEXITY_API_KEY,
baseURL: "https://api.perplexity.ai",
});
}
return instance;
}
Step 2: Search with Full Response Parsing // src/perplexity/search.ts
import { getClient, PerplexityChatCompletion } from "./client";
export type SearchModel = "sonar" | "sonar-pro" | "sonar-reasoning-pro" | "sonar-deep-research";
export type RecencyFilter = "hour" | "day" | "week" | "month";
export interface SearchOptions {
model?: SearchModel;
systemPrompt?: string;
maxTokens?: number;
temperature?: number;
searchRecencyFilter?: RecencyFilter;
searchDomainFilter?: string[]; // max 20 domains
returnRelatedQuestions?: boolean;
returnImages?: boolean;
}
export interface SearchResult {
answer: string;
citations: string[];
relatedQuestions: string[];
usage: {
promptTokens: number;
completionTokens: number;
totalTokens: number;
citationTokens?: number;
searchQueries?: number;
};
model: string;
}
export async function search(
query: string,
opts: SearchOptions = {}
): Promise<SearchResult> {
const client = getClient();
const response = (await client.chat.completions.create({
model: opts.model || "sonar",
messages: [
...(opts.systemPrompt
? [{ role: "system" as const, content: opts.systemPrompt }]
: []),
{ role: "user" as const, content: query },
],
max_tokens: opts.maxTokens,
temperature: opts.temperature,
...(opts.searchRecencyFilter && { search_recency_filter: opts.searchRecencyFilter }),
...(opts.searchDomainFilter && { search_domain_filter: opts.searchDomainFilter }),
...(opts.returnRelatedQuestions && { return_related_questions: true }),
...(opts.returnImages && { return_images: true }),
} as any)) as unknown as PerplexityChatCompletion;
return {
answer: response.choices[0].message.content || "",
citations: response.citations || [],
relatedQuestions: response.related_questions || [],
usage: {
promptTokens: response.usage?.prompt_tokens || 0,
completionTokens: response.usage?.completion_tokens || 0,
totalTokens: response.usage?.total_tokens || 0,
citationTokens: (response.usage as any)?.citation_tokens,
searchQueries: (response.usage as any)?.num_search_queries,
},
model: response.model,
};
}
Step 3: Retry with Exponential Backoff // src/perplexity/retry.ts
export async function withRetry<T>(
operation: () => Promise<T>,
opts = { maxRetries: 3, baseDelayMs: 1000, maxDelayMs: 30000 }
): Promise<T> {
for (let attempt = 0; attempt <= opts.maxRetries; attempt++) {
try {
return await operation();
} catch (err: any) {
if (attempt === opts.maxRetries) throw err;
const status = err.status || err.response?.status;
// Only retry on rate limit (429), timeout (408), or server errors (5xx)
if (status && status !== 429 && status !== 408 && status < 500) throw err;
const delay = Math.min(
opts.baseDelayMs * Math.pow(2, attempt) + Math.random() * 500,
opts.maxDelayMs
);
await new Promise((r) => setTimeout(r, delay));
}
}
throw new Error("Unreachable");
}
// Usage
const result = await withRetry(() =>
search("latest AI developments", { model: "sonar-pro" })
);
Step 4: Python Patterns # perplexity_client.py
import os, hashlib, json
from openai import OpenAI
from functools import lru_cache
@lru_cache(maxsize=1)
def get_client() -> OpenAI:
return OpenAI(
api_key=os.environ["PERPLEXITY_API_KEY"],
base_url="https://api.perplexity.ai",
)
def search(
query: str,
model: str = "sonar",
system_prompt: str | None = None,
max_tokens: int | None = None,
search_recency_filter: str | None = None,
search_domain_filter: list[str] | None = None,
) -> dict:
client = get_client()
messages = []
if system_prompt:
messages.append({"role": "system", "content": system_prompt})
messages.append({"role": "user", "content": query})
kwargs = {"model": model, "messages": messages}
if max_tokens:
kwargs["max_tokens"] = max_tokens
if search_recency_filter:
kwargs["search_recency_filter"] = search_recency_filter
if search_domain_filter:
kwargs["search_domain_filter"] = search_domain_filter
response = client.chat.completions.create(**kwargs)
raw = response.model_dump()
return {
"answer": response.choices[0].message.content,
"citations": raw.get("citations", []),
"usage": {
"prompt_tokens": response.usage.prompt_tokens,
"completion_tokens": response.usage.completion_tokens,
"total_tokens": response.usage.total_tokens,
},
"model": response.model,
}
Step 5: Citation Formatter // src/perplexity/citations.ts
export function formatCitationsAsMarkdown(
answer: string,
citations: string[]
): string {
// Replace [1], [2], etc. with markdown links
let formatted = answer;
citations.forEach((url, i) => {
const marker = `[${i + 1}]`;
formatted = formatted.replaceAll(marker, `${i + 1}`);
});
return formatted;
}
export function formatCitationsAsFootnotes(
answer: string,
citations: string[]
): string {
const footnotes = citations
.map((url, i) => `[${i + 1}]: ${url}`)
.join("\n");
return `${answer}\n\n---\n${footnotes}`;
}
Error Handling Pattern Use Case Benefit Typed response wrapper All API calls Access citations without any casts Retry with backoff Transient failures Handles 429 rate limits gracefully Citation formatter User-facing output Converts [1] markers to clickable links Python @lru_cache Client reuse Single client instance across calls
Output
Type-safe Perplexity client with full response typing
Search function with all Perplexity-specific parameters
Automatic retry with exponential backoff and jitter
Citation formatting utilities
