Florida Secretary of State API: Direct Access to Business Entity Data
If you're building applications that need to verify business entities registered in Florida, the OpenSOSData FL Secretary of State API provides direct access to official state records without the overhead of web scraping or manual lookups.
Florida businesses file with the Division of Corporations under the Secretary of State's office. Whether you're managing compliance checks, due diligence workflows, or customer verification systems, querying this data programmatically saves time and reduces errors.
Why Use an API Instead of Manual Lookups?
The Florida Secretary of State website allows manual searches, but integrating that process into your application requires building web scrapers, handling rate limits, and maintaining brittle parsing logic as the site structure changes. An API eliminates these friction points:
- Consistency: Structured JSON responses, every time
- Speed: Millisecond response times with caching
- Scale: Handle hundreds or thousands of lookups without scraper maintenance
- Reliability: Dedicated infrastructure that stays operational
What Data Does the API Return?
A single lookup returns comprehensive entity information:
- Entity name and official business type
- Unique state identification number
- Current entity status (active, dissolved, etc.)
- Formation date
- Registered agent name and address
- Principal address
- Officer names and titles
This mirrors the data you'd gather from official Secretary of State filings, but delivered in machine-readable format ready for your application logic.
Pricing: $0.0314 Per Lookup
OpenSOSData charges $0.0314 per lookup—a Pi-inspired pricing model. This breaks down to roughly 100 lookups for $3.14 minimum wallet balance. No subscriptions, no per-month commitments.
Compare this to alternatives:
- OpenCorporates: $0.10–$0.50 per lookup
- Cobalt Intelligence: $0.50–$2.00 per lookup
- Middesk: $1.00+ per lookup plus monthly fees
For a business verification system processing 1,000 Florida lookups monthly, OpenSOSData costs roughly $31.40, compared to $100–$500+ with competitors.
Smart Caching with Redis
The API implements a 7-day Redis cache for frequently requested entities. Repeat lookups for the same business entity return instantly at no additional cost. For real-time data—if an entity was just registered or status changed—append ?fresh=true to force a live scrape from the Secretary of State.
This hybrid approach balances cost efficiency with freshness. Most compliance workflows benefit from cached data for recent entities, while legal due diligence may require fresh confirmation.
Coverage Across 50+ States
While this guide focuses on Florida, OpenSOSData covers all major U.S. jurisdictions including CA, TX, NY, DE, and 47 others, plus Puerto Rico, Virgin Islands, and D.C. A single API integration handles multi-state lookups with consistent response formats.
Quick Start: Making Your First FL SOS API Call
The endpoint is a POST request to https://api.opensosdata.com/v1/lookup. You'll need an API key from the OpenSOSData dashboard.
Example Request
curl -X POST https://api.opensosdata.com/v1/lookup \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{
"state": "FL",
"entity_name": "Apple Inc"
}'Example Response
{
"entity_name": "APPLE INC",
"entity_type": "Foreign For-Profit Corporation",
"state": "FL",
"entity_id": "N12345678",
"status": "Active",
"formation_date": "2010-03-15",
"registered_agent": {

},
"principal_address": "One Apple Park Way, Cupertino, CA 95014",
"officers": [
{
"name": "Tim Cook",
"title": "Chief Executive Officer"
}
],
"cached": false,
"lookup_cost": 0.0314
}The cached: false flag indicates this was a fresh lookup. Subsequent queries for the same entity within 7 days return cached: true at zero cost.
Common Use Cases for FL SOS API
Customer Onboarding
Verify that new business customers are legitimate registered entities in Florida before activating their accounts. Combine with address verification for KYC compliance.
Supplier Due Diligence
Bulk-check vendor entities and officer information before contract execution. Identify mismatches between claimed business names and official registrations.
Fraud Detection
Flag business applications with entity names that don't match official Florida SOS records, or verify registered agents are real people at registered addresses.
Compliance Reporting
Automate annual verification runs to ensure business counterparties remain active and maintain current officer information for audit trails.
Authentication and API Keys
All requests require a Bearer token in the Authorization header. Keys are generated in the OpenSOSData dashboard and tied to a wallet. As you make lookups, costs are deducted from your balance. Top up anytime—no lock-in contracts.
Error Handling
The API returns standard HTTP status codes. A 404 means the entity wasn't found in Florida SOS records. A 401 indicates an invalid or expired API key. Rate limiting is enforced per-key; check response headers for remaining quota.
Documentation and Support

Why Florida Matters
Florida is the third-largest state by population and a hub for corporate registrations. Many businesses register here regardless of operational location due to business-friendly policies. A robust FL Secretary of State API integration is essential for any platform serving national B2B customers.
