]What Are the Main Use Cases for Company Enrichment?
Company enrichment APIs solve the problem of incomplete CRM data. When you only have a prospect's email domain or website, enrichment fills the gaps automatically. Here are the primary applications:
Sales Lead Qualification: Sales development representatives use enrichment to instantly qualify inbound leads. Knowing a company's size and industry before the first call improves conversion rates by enabling personalized outreach.
CRM Data Hygiene: Marketing operations teams run enrichment on existing contact databases to fill missing company fields. This improves segmentation accuracy and campaign targeting.
Competitive Intelligence: Product and strategy teams monitor competitor company data including headcount changes, new locations, and industry pivots.
Account-Based Marketing: ABM platforms integrate enrichment APIs to build target account lists based on firmographic criteria like company size, industry, and geography.
Lead Scoring Automation: Marketing automation systems use enriched company data to score leads based on ideal customer profile fit—prioritizing companies matching target size and industry.
How Does This Compare to Other Company Data APIs?
The B2B data enrichment market includes several established players. Here's how this API positions against alternatives:
| Provider | Free Tier | Starting Price | Data Points | Best For |
|---|---|---|---|---|
| TechnologyChecker | 100/month | $29/month | 10 fields | SMBs, startups, developers |
| Clearbit | None | Custom pricing | 100+ fields | Enterprise sales teams |
| ZoomInfo | None | $15,000+/year | 200+ fields | Large sales organizations |
| Hunter.io | 25/month | $49/month | Limited company data | Email finding focus |
| Apollo.io | 50 credits/month | $49/month | 50+ fields | Outbound prospecting |
TechnologyChecker's API offers the most generous free tier among pure company enrichment tools. While enterprise solutions like Clearbit and ZoomInfo provide deeper data coverage, their pricing models exclude smaller teams and individual developers.
How Do You Integrate Company Enrichment Into Your Workflow?
The API's RESTful design enables integration with virtually any platform supporting HTTP requests. Common integration patterns include:
- CRM Webhooks: Trigger enrichment when new contacts are created in Salesforce, HubSpot, or Pipedrive. Map returned fields to custom company properties.
- Zapier/Make Automation: Build no-code workflows that enrich new form submissions, spreadsheet rows, or database entries automatically.
- Custom Applications: Call the API directly from Python, JavaScript, or any language with HTTP client libraries.
- Spreadsheet Enrichment: Use Google Apps Script or Excel macros to bulk enrich company lists by domain.
Python Integration Example:
import requests
def enrich_company(domain, api_key):
url = f"https://api.technologychecker.io/v1/company?domain={domain}"
headers = {
"Accept": "application/json",
"Authorization": f"Bearer {api_key}"
}
response = requests.get(url, headers=headers)
return response.json()
# Usage
