Oxylabs SERP API vs Google Custom Search API: overview
Oxylabs SERP API
Oxylabs SERP Scraper API provides structured SERP data from Google, Bing, Baidu, and other engines by routing live requests through its own 102M+ IP proxy network — no cached data. Custom JavaScript parsers allow callers to define exactly what is extracted from each result page. Oxylabs was founded in 2015 and is headquartered in Vilnius, Lithuania, with offices in the US and UK. It holds ISO 27001 certification. The SERP API uses asynchronous delivery with webhooks or polling, with typical completion times of 5–30 seconds depending on target and proxy routing. Notable clients include Reebok, Adidas, and Nielsen (per company website; independently unverifiable).
Google Custom Search API
Google Custom Search JSON API provides programmatic access to Google's Programmable Search Engine (PSE), formerly Google Custom Search Engine. Unlike a general web search API, the PSE only searches websites explicitly configured in the PSE console — it does not provide access to Google's full web index. Free usage is capped at 100 queries per day; beyond that, pricing is $5 per 1,000 queries with a hard 10,000 queries per day maximum per project. The API is part of Google Cloud and inherits its compliance framework including SOC 2, ISO 27001, FedRAMP, and GDPR. It has been available since approximately 2011.

Oxylabs SERP API vs Google Custom Search API: pros and cons
| Oxylabs SERP API | |
|---|---|
| + | 102M+ residential and datacenter IP pool — high success rate against bot detection on Google, Bing, and Baidu |
| + | Real-time crawling — every response reflects the current SERP state at request time, not a cached snapshot |
| + | Custom JavaScript parsers enable caller-defined output schemas beyond a fixed SERP data model |
| + | ISO 27001 certified — documented information security management for compliance-sensitive procurement |
| + | Multi-engine support with per-engine parameter customisation for Google, Bing, Baidu, and Yahoo |
| - | Enterprise-only pricing — requires a sales process before access; no self-serve free tier documented |
| - | 5–30 second response times via asynchronous delivery make it unsuitable for real-time user-facing search |
| - | Per-request pricing is expensive at high volume compared to DataForSEO standard queue pricing |
| - | Custom parsers require JavaScript maintenance when target sites update HTML structure |
| Google Custom Search API | |
|---|---|
| + | Official Google product — the only legally compliant way to access Google search results via API without scraping risk |
| + | Full Google Cloud compliance: SOC 2, ISO 27001, GDPR, and FedRAMP through Google Cloud — covers regulated procurement |
| + | 100 free queries/day sufficient for internal tools, development environments, and low-volume dashboards |
| + | All Google API client libraries available (Python, Java, Node.js, Go, Ruby) — no custom HTTP client required |
| - | Does NOT search the full Google web index — only searches sites configured in the Programmable Search Engine console |
| - | 10,000 query/day hard cap per project makes it unsuitable for any production-scale search application |
| - | $5/1K queries is 1.7–5× more expensive than Bing Search API for a more restricted index |
| - | PSE configuration requires maintaining an explicit list of target sites — significant operational overhead for broad web search |
