Lead generation still runs on data. The problem is that most free scraping tools either break after a week, get blocked by Cloudflare, or return garbage data.
I spent the last few months testing tools that actually hold up in production. Here are 9 that work as of March 2026, with real use cases for each.
1. YellowPages Business Lead Scraper
YellowPages.com is still one of the largest directories for local business data. The catch: Cloudflare protection makes it hard to scrape reliably.
What you get: Business name, address, phone, email, website, hours, categories, ratings.
Best for: Local lead lists, competitor analysis, enrichment pipelines.
YellowPages Scraper on Apify handles the anti-bot layer and returns structured JSON. Pay-per-result pricing means you only pay for data you actually get.
2. Secretary of State Business Entity Search
Every US state maintains a public database of registered businesses. This data is gold for KYC, compliance, sales prospecting, and competitive intelligence.
What you get: Entity name, status, filing date, registered agent, formation state, officer names.
Best for: B2B sales verification, due diligence, compliance workflows.
State-by-state scrapers:
- California Business Search
- Texas Business Search
- New York Business Search
- US Business Entity Search (multi-state)
3. SEC EDGAR Company Filings API
SEC EDGAR is the single best source for public company financial data. The full-text search API is free and returns structured results.
What you get: 10-K, 10-Q, 8-K filings, company CIK, filing dates, document URLs.
Best for: Financial research, investor lead lists, public company monitoring.
SEC EDGAR Search on Apify wraps the EDGAR full-text search with pagination and structured output.
4. NPPES NPI Registry for Healthcare Leads
The National Plan and Provider Enumeration System has data on every licensed healthcare provider in the US. Over 7 million records.
What you get: Provider name, specialty, practice address, phone, taxonomy codes.
Best for: Healthcare sales, provider directories, medical device marketing.
NPI Registry Search on Apify provides clean JSON output with filtering by name, specialty, state, and city.
5. FEC Campaign Finance Search
Federal Election Commission data covers every political donation and campaign expenditure in the US.
What you get: Donor names, amounts, employers, recipient committees, transaction dates.
Best for: Political research, donor prospecting, compliance screening.
FEC Campaign Finance on Apify handles the FEC API pagination and returns structured donor/committee data.
6. IRS 990 Nonprofit Filings
Every US tax-exempt organization files a 990. This data reveals revenue, expenses, executive compensation, and mission statements.
What you get: Organization name, EIN, revenue, assets, tax period, filing URL.
Best for: Nonprofit sales, grant research, foundation prospecting.
IRS 990 Search on Apify queries the IRS e-file index with full-text search.
7. CMS Open Payments (Sunshine Act)
Every payment from a pharmaceutical or medical device company to a US physician is public record.
What you get: Physician name, specialty, company, payment amount, nature of payment.
Best for: Pharma sales intelligence, compliance monitoring, competitive analysis.
Open Payments Search on Apify provides structured search across the full CMS dataset.
8. CFPB Consumer Complaints Database
The Consumer Financial Protection Bureau publishes every complaint filed against financial companies.
What you get: Company name, product, issue, state, date, company response.
Best for: Competitive intelligence on financial products, risk monitoring, market research.
CFPB Complaints on Apify wraps the CFPB API with clean filtering and pagination.
9. BLS Economic Data
The Bureau of Labor Statistics publishes employment, inflation, wages, and industry data for every US metro area.
What you get: Series data, time periods, values, area codes, industry classifications.
Best for: Market sizing, compensation benchmarking, location intelligence for sales territories.
BLS Economic Data on Apify handles the BLS API v2 with series search and data retrieval.
Why These Work When Others Break
Most free scraping tools fail because they use basic HTTP requests against sites with modern anti-bot protection. The tools above work because they either:
- Hit official APIs (SEC, NPI, FEC, IRS, CMS, CFPB, BLS) -- no scraping needed, just clean wrappers around government endpoints
- Use browser automation with stealth (YellowPages, state SOS portals) -- proper headless Chrome with fingerprint rotation
Government APIs are the most underrated data source for lead generation. They are free, legal, reliable, and rarely change. The hard part is knowing they exist and handling the quirks of each one.
If you are building enrichment pipelines, sales prospecting workflows, or compliance tools, these are the building blocks.
