Beyond Google: 5 Specialized APIs for Searching Corporate Web Data

In the past, discovering good corporate intelligence often involved hours of manual browsing of company websites and LinkedIn profiles, and searching industry databases. Today, for this, there are custom APIs that extract structured company data from the best API search company’s homepage and beyond in seconds. Look up any of their tools, and you’ll see they are not just scraping; they’re turning raw web content into actionable insights that sales teams, investors, and market researchers rely on to make good decisions.

Traditional search engines like Google are great at identifying relevant pages, but they were not designed for what comes next: extracting, structuring, and analyzing the data on those pages. The bridge between “Crawl, Index, Retrieve” and “LLM-ready” data is where custom APIs can deliver meaningful value.

Why Traditional Search Falls Short for Corporate Data

Google’s search algorithm favours relevance and authority, compiling ranked lists of web pages. That’s great for human readers who are clicking through results. But when you want to scrape firmographic information from 500 company websites, go through funding rounds for an industry, or enrich CRM records with current employee numbers, Google’s HTML snippets are terrible to parse.

Dedicated APIs bridge this gap by providing search and intelligent extraction in a single API. But instead of links, they return responses in structured JSON with the precise data points you want, company revenue, technology stack, team roster or recent news mentions, already parsed and normalized. This shift from hands-on research to automated extraction is changing how companies collect competitive intelligence.

4. Diffbot: Utilizing the Knowledge Graph for 2 Billion+ Structured Entities

We have a crawling and automatic extraction pipeline that has structurally organized over 98% of the public web into a knowledge graph comprising more than 10 billion entities (and about 2 trillion facts). This isn’t some scraped HTML; it’s an internet-scale database of organizations, people, products, articles, and events, with verified relationships between them.

Knowledge Graph capabilities:

  • Query against 20+ types of entities (companies, people, products, locations, events)
  • Automatic facts from common/distinct web-wide crawls
  • Relations between entities are maintained(company, parent company, executive job history, product makers)
  • Formats may be of any kind; machine vision and NLP extract information from formats

When you look up a company in Diffbot, you’re not pulling individual pieces of data. Full Profile: Get a full profile with funding, key management and employees, product imagery and details, news links, and other verified connections to similar companies. This networked structure enables advanced research questions that are not possible with single-source APIs.

5. People Data Labs (PDL): Deep-Dive into B2B and Professional Profile Intelligence
