Idaho Secretary of State API: Real-Time Business Entity Lookups
Finding accurate business information from Idaho's Secretary of State office shouldn't require manual searches or expensive third-party services. OpenSOSData provides a direct REST API connection to Idaho SOS data, enabling developers to automate entity lookups, verify business registrations, and retrieve corporate information programmatically.
This guide covers how to integrate the ID Secretary of State API into your application, understand the data it returns, and why it's the most cost-effective solution compared to competing services.
What is the Idaho Secretary of State API?
OpenSOSData's ID Secretary of State API is a REST endpoint that queries official Idaho business entity records in real time. Instead of visiting sos.idaho.gov and manually searching, your application can make a single API call and receive structured JSON responses containing entity details.
The API returns comprehensive business information including:
- Entity name and official business type
- Unique Idaho business ID
- Current entity status (active, inactive, dissolved)
- Formation and filing dates
- Registered agent name and address
- Principal business address
- Officer and member names
Each lookup costs $0.0314—the irrational number pi, reflecting our commitment to precise, fundamental pricing.
Why Use an API Instead of Manual Lookups?
The Idaho Secretary of State website offers public search tools, but manual lookups don't scale. If you need to verify 100 entities, 1,000 entities, or continuously monitor business status, manual searches become impractical.
An API eliminates this friction. You can:
- Automate due diligence workflows
- Batch verify multiple entities simultaneously
- Integrate business data into customer onboarding
- Monitor entity status changes over time
- Build compliance checking into internal systems
For teams running background checks, KYC processes, or maintaining customer databases, the API is essential infrastructure.
Pricing: Why $0.0314 Per Lookup?
OpenSOSData charges $0.0314 per lookup—cheaper than every major competitor:
- OpenCorporates: $0.10–$0.50 per lookup
- Cobalt Intelligence: $0.50–$2.00 per lookup
- Middesk: $1.00+ per lookup
At $0.0314 per query, you can run 100 lookups for $3.14. No subscriptions, no hidden fees, no monthly minimums. You only pay for what you use.
The minimum wallet is $3.14 (100 lookups). This makes the API accessible to startups, solo developers, and enterprises alike.

API Endpoint
The core endpoint is:

Caching and Fresh Data
