Query Florida Business Entities with OpenSOSData's Secretary of State API

Florida Secretary of State API: Direct Access to Business Entity Data

The Florida Secretary of State maintains one of the largest business registries in the United States. If you need to verify entity formation dates, registered agent information, officer details, or corporate status for Florida businesses, manual lookups through the state portal are slow and labor-intensive.

OpenSOSData provides a REST API that connects directly to Florida's Secretary of State database, returning structured business entity data in milliseconds. This post covers what the FL secretary of state API does, how it works, and why it's the most cost-effective option for developers and compliance teams.

What You Get from the FL Secretary of State API

Each API call returns comprehensive entity data:

• Entity name and legal structure (LLC, Corporation, etc.)
• Unique state entity ID
• Current registration status
• Formation date
• Registered agent name and address
• Principal business address
• Officer names and titles

Data is cached for 7 days via Redis for improved performance on repeated queries. Use the ?fresh=true parameter to force a real-time scrape if you need the absolute latest state records.

Pricing: $0.0314 Per Lookup

OpenSOSData uses Pi pricing ($0.0314 per lookup), a flat rate that undercuts every major competitor. Here's the market comparison:

• OpenSOSData: $0.0314 per lookup
• OpenCorporates: $0.10–$0.50 per lookup
• Cobalt Intelligence: $0.50–$2.00 per lookup
• Middesk: $1.00+ per lookup

No subscription fees. No monthly minimums. No seat limits. You only pay for what you query. A $3.14 wallet balance (the minimum) gives you 100 lookups—enough to test integration or run small batches.

Who Needs This API

The FL secretary of state API is built for:

• Compliance teams: Verify business registration and officer information during onboarding
• Due diligence platforms: Embed entity lookups into risk assessment workflows
• Developers: Build business search tools without maintaining state data infrastructure
• Financial services: Validate business entities for lending, payments, or insurance
• Legal tech: Cross-reference business records during contract review or entity formation

API Coverage and State Support

Florida is one of 49 actively supported jurisdictions. OpenSOSData also covers all major business formation states including California, Delaware, Texas, Wyoming, New York, and others. The same API endpoint works across all supported states—just change the state parameter in your request.

How the API Works: State-by-State Lookups

The API uses a single POST endpoint: https://api.opensosdata.com/v1/lookup

You submit an entity name or ID, specify the state (FL), and receive structured JSON within seconds. The API handles parsing, data normalization, and validation, so you don't have to scrape or manage state websites.

Quick Start: Your First FL Secretary of State Lookup

Here's a real curl example:

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": "Google LLC",
    "fresh": false
  }'

Response (example):

{
  "entity_id": "N000001234",
  "entity_name": "Google LLC",
  "entity_type": "Limited Liability Company",
  "status": "Active",
  "formation_date": "2000-10-02",
  "registered_agent": {
    "name": "Registered Agent Name",
    "address": "123 Main Street, Tallahassee, FL 32301"
  },
  "principal_address": "1600 Amphitheatre Parkway, Mountain View, CA 94043",
  "officers": [
    {
      "name": "Officer Name",
      "title": "Manager"
    }
  ],
  "last_updated": "2024-01-15"
}

To get started:

1. Sign up at https://opensosdata.com (currently on waitlist)
2. Add at least $3.14 to your wallet (100 lookups)
3. Grab your API key from the dashboard
4. Make your first request using the endpoint above

Caching and Real-Time Data

By default, the API returns cached results (7-day Redis cache) to minimize latency and cost. If you need current data—for example, to verify a status change filed this morning—add "fresh": true to your request. This forces a live scrape of the Florida Secretary of State database.

For most use cases, cached data is sufficient and faster. Use fresh queries selectively to manage costs.

Integration Patterns

Batch Processing: Submit multiple entity lookups in a single request to reduce overhead. Each entity is charged at $0.0314.

Webhook Callbacks: For async workflows, you can register webhooks to receive results as they complete, rather than blocking on synchronous API calls.

Error Handling: The API returns standard HTTP status codes. A 404 means the entity was not found in Florida's registry. A 401 means your API key is missing or invalid. See the full OpenAPI spec at https://opensosdata.com/openapi.yaml for complete error documentation.

Why OpenSOSData Over Manual Lookups or Competitors

Cost: At $0.0314 per lookup, you'll spend less than $315 to query 10,000 Florida entities. Manual portal lookups are free but require hours of labor. Competitors charge 3–60 times more per query.

Speed: API responses arrive in milliseconds. Portal scraping takes seconds per entity. If you query 100 entities daily, the time savings alone justify integration.

Automation: Build compliance workflows that automatically validate businesses without human intervention. Embed lookups into onboarding, risk scoring, or periodic audit processes.

Reliability: The API monitors Florida's SOS database continuously. You don't manage data infrastructure, licensing agreements, or state website changes.

No Friction: No subscription contracts. No minimum commitments. Start with $3.14 and scale up as needed.

Technical Details and Documentation

Full OpenAPI specification available at https://opensosdata.com/openapi.yaml. The spec includes request schemas, response formats, error codes, authentication methods, and rate limits.

Supported authentication: Bearer token (recommended for production) and API key headers.

Rate limits: 100 requests per minute per API key. Contact support if you need higher limits for batch operations.

Next Steps

If you're building a business search tool, compliance platform, or entity verification workflow, the FL secretary of state API removes the need to maintain your own state data infrastructure or pay premium prices for lookup services.

Sign up at https://opensosdata.com, add a wallet balance, and start querying. Your first 100 lookups cost $3.14.
