Minnesota Secretary of State API Overview
The Minnesota Secretary of State maintains comprehensive records of business entities registered within the state. Accessing this data programmatically can accelerate due diligence, compliance workflows, and business intelligence operations.
OpenSOSData provides a REST API interface to Minnesota Secretary of State business entity records, enabling developers to query formation dates, registered agents, principal addresses, officer information, and entity status without manual database searches.
What Data Does the MN Secretary of State API Return?
A successful API lookup returns structured data including:
- Entity name and type (LLC, Corporation, Partnership, etc.)
- Unique entity ID
- Current registration status
- Formation date
- Registered agent name and address
- Principal address
- Officer names and titles
This data mirrors what you'd find on the Minnesota Secretary of State public search portal, but delivered programmatically with zero manual work.
Pricing & Accessibility
OpenSOSData charges $0.0314 per lookup—a Pi-based pricing model that undercuts traditional competitors significantly. No subscription required. Get started with a minimum wallet balance of $3.14 (approximately 100 lookups).
Compare this to alternatives: OpenCorporates charges $0.10–$0.50 per lookup, Cobalt Intelligence ranges from $0.50–$2.00, and Middesk starts at $1.00+. For high-volume operations, the savings accumulate quickly.
Coverage Across US States
Minnesota is one of 47 actively supported jurisdictions, including California, Texas, New York, Delaware, and all major business registration states. Whether you're building a national compliance tool or focusing on regional markets, coverage is comprehensive.
Real-Time and Cached Lookups
By default, the API returns results from a 7-day Redis cache, providing fast response times (typically under 200ms). If you need current data immediately, append ?fresh=true to force a real-time scrape of the Minnesota Secretary of State database.
This dual approach balances performance with data freshness—cached lookups are instant, fresh queries ensure you're working with the latest registration status.
