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.

| DataForSEO | |
|---|---|
| + | $0.0006/SERP standard queue — the lowest published per-query price of any provider in this review |
| + | 700 results per keyword depth — enables bulk enumeration well beyond the 10–100 results most APIs cap at |
| + | 7 engine support including Baidu, Naver, and Seznam — broadest non-English search engine coverage in this category |
| + | Raw HTML mode available for teams building custom parsers on top of SERP page data |
| + | Enterprise clients include Samsung, Amazon, Vodafone, Adobe, HubSpot, Airbnb, Oracle, and Siemens |
| - | Primarily designed for SEO analytics — no LLM validation, deduplication, or structured event extraction for AI pipelines |
| - | No free tier documented on the primary API page — deposit model requires upfront commitment before testing |
| - | Standard queue ~5 minute turnaround is unsuitable for real-time AI agent use cases requiring sub-second responses |
| - | Secondary office in Kharkiv, Ukraine introduces business continuity considerations for mission-critical enterprise SLAs |
| 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 |
