SerpApi SDK Patterns

Overview

Production patterns for SerpApi: typed result interfaces, response caching (critical since each search costs credits), multi-engine abstraction, and async search with the Searches Archive API.

Instructions

Step 1: Typed Result Interfaces

interface SerpApiOrganicResult {
  position: number;
  title: string;
  link: string;
  snippet: string;
  displayed_link: string;
  source?: string;
}

interface SerpApiSearchResult {
  search_metadata: { id: string; status: string; created_at: string };
  search_parameters: Record<string, string>;
  organic_results: SerpApiOrganicResult[];
  answer_box?: { answer?: string; snippet?: string; title?: string };
  knowledge_graph?: { title: string; description?: string; type?: string };
  related_questions?: Array<{ question: string; snippet: string }>;
  pagination?: { next: string };
}

Step 2: Cached Search Client

import { getJson } from 'serpapi';
import { LRUCache } from 'lru-cache';

const cache = new LRUCache<string, SerpApiSearchResult>({
  max: 500,
  ttl: 3600_000, // 1 hour -- search results are relatively stable
});

async function cachedSearch(params: Record<string, any>): Promise<SerpApiSearchResult> {
  const key = JSON.stringify(params);
  const cached = cache.get(key);
  if (cached) return cached;

  const result = await getJson({
    ...params,
    api_key: process.env.SERPAPI_API_KEY,
  }) as SerpApiSearchResult;

  cache.set(key, result);
  return result;
}

Step 3: Multi-Engine Search Abstraction

import serpapi, os

class SearchService:
    ENGINES = {
        "web": {"engine": "google", "query_param": "q"},
        "news": {"engine": "google_news", "query_param": "q"},
        "images": {"engine": "google_images", "query_param": "q"},
        "youtube": {"engine": "youtube", "query_param": "search_query"},
        "bing": {"engine": "bing", "query_param": "q"},
        "shopping": {"engine": "google_shopping", "query_param": "q"},
    }

    def __init__(self):
        self.client = serpapi.Client(api_key=os.environ["SERPAPI_API_KEY"])

    def search(self, query: str, engine: str = "web", **kwargs) -> dict:
        config = self.ENGINES[engine]
        params = {
            "engine": config["engine"],
            config["query_param"]: query,
            **kwargs,
        }
        return self.client.search(**params)

# Usage
svc = SearchService()
web = svc.search("Claude AI")
news = svc.search("Claude AI", engine="news")
videos = svc.search("Claude AI tutorial", engine="youtube")

Step 4: Async Search (Background Processing)

# Submit search asynchronously -- retrieve later
result = client.search(engine="google", q="expensive query", async_search=True)
search_id = result["search_metadata"]["id"]

# Later: retrieve from archive (no extra credit charge)
import time
while True:
    archived = client.search(engine="google", search_id=search_id)
    if archived["search_metadata"]["status"] == "Success":
        break
    time.sleep(2)
