SerpAPI
Search engine results API that provides structured JSON data from Google, Bing, YouTube, and 100+ other search engines without managing proxies or browsers.
Best for developers who need structured SERP data for search result scraping, price comparison, or content aggregation without managing proxy infrastructure.
Use Cases
Free Tier
250 searches/month, 50 requests/hour, access to all search engines, no credit card required
How to Maximize the Free Tier
SerpAPI's 250 free searches/month is best used for prototyping SERP-based features or light monitoring. Cache results aggressively — the same query shouldn't be re-fetched within the same day unless data freshness is critical. Prioritize Google and YouTube endpoints since they provide the most value. For production, the Starter plan ($25/month for 1,000 searches) is cost-effective at $0.025/search. Watch the 50 requests/hour limit carefully when building batch crawlers.
Getting Started
Sign up at serpapi.com → get API key from dashboard → install SDK (pip install google-search-results or npm install google-search-results) → choose search engine endpoint → make API call with query parameter → parse structured JSON response.
Pros
- Engine coverage: Supports 100+ search engines including Google, Bing, YouTube, Baidu, Walmart, and Apple App Store from a single API
- Structured output: Returns clean, parsed JSON with organic results, knowledge graphs, featured snippets, and related questions — no HTML scraping needed
- Pay-per-success: Only successful searches are billed — failed requests and errors don't count against your quota
Cons
- Low free tier: 250 searches/month is only viable for prototyping and small side projects, not production workloads
- Rate limiting: 50 requests/hour cap on free tier can bottleneck batch data collection tasks
- Google dependency: Google results may be blocked or rate-limited more aggressively than other engines due to scraping detection
