ID Secretary of State API: Business Entity Lookup

ID Secretary of State API: Instant Business Entity Lookups

Building applications that need to verify Idaho business entities? The OpenSOSData ID Secretary of State API gives you direct programmatic access to Idaho corporation, LLC, and partnership records without navigating government portals or paying enterprise SaaS rates.

This REST API queries the Idaho Secretary of State business database in real time, returning entity details like formation dates, registered agent information, principal addresses, and officer names. Whether you're building compliance tools, due diligence workflows, or business intelligence platforms, this API eliminates manual lookup friction.

Why Use an ID Secretary of State API?

The Idaho Secretary of State website works fine for occasional manual lookups, but it's not built for developers. Scraping is fragile. Building your own data pipeline is expensive. An API abstracts that complexity away.

OpenSOSData covers Idaho alongside 49 other states and territories, meaning your integration scales geographically without rewriting logic. The API returns structured JSON—entity type, status, formation date, registered agent, principal address, and officer roster. No parsing HTML tables. No OCR. Just clean data.

Use Cases

Compliance & KYC: Verify business registration status before onboarding customers or vendors.
Due Diligence: Check officer names, formation dates, and agent information during M&A research.
Credit & Risk:

Validate entity details against loan applications or trade credit requests.
Business Intelligence: Track formations, dissolutions, and registered agent changes over time.

Pricing: Pi-Based Lookup Costs

OpenSOSData charges $0.0314 per lookup—a reference to Pi (π), the mathematical constant. No subscriptions. No monthly minimums. No per-seat licensing.

Your minimum wallet is $3.14, which gives you 100 lookups. That means:

100 Idaho lookups: $3.14
1,000 lookups: $31.40
10,000 lookups: $314.00

Compare this to competitors: OpenCorporates charges $0.10–$0.50 per lookup, Cobalt Intelligence runs $0.50–$2.00, and Middesk starts at $1.00+. OpenSOSData undercuts them all, especially at scale.

API Response & Data Fields

A successful lookup returns:

Entity name
Entity type (Corporation, LLC, LP, etc.)
Unique ID (assigned by Idaho SOS)
Status (Active, Dissolved, etc.)
Formation date
Registered agent name and address
Principal address
Officer names and titles

Data is cached for 7 days on Redis for faster subsequent queries. If you need real-time data (e.g., checking for same-day filings), pass ?fresh=true to force a live scrape from the Idaho SOS database.

Quick Start: ID Secretary of State API

1. Sign Up

Head to opensosdata.com and join the waitlist. Once approved, you'll receive API credentials and can fund your wallet with a minimum of $3.14.

2. Make Your First Lookup

Post to the lookup endpoint with an entity name or ID:

curl -X POST https://api.opensosdata.com/v1/lookup \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "state": "ID",
    "query": "Albertsons Companies Inc"
  }'

3. Parse the Response

The API returns JSON:

{
  "entity_name": "Albertsons Companies Inc",
  "entity_type": "Corporation",
  "entity_id": "080026991",
  "status": "Active",
  "formation_date": "1992-07-14",
  "registered_agent": {
    "name": "Registered Agent Name",
    "address": "123 Main St, Boise, ID 83702"
  },
  "principal_address": "250 Parkcenter Blvd, Boise, ID 83706",
  "officers": [
    {
      "name": "John Doe",
      "title": "President"
    }
  ],
  "lookup_cost": 0.0314,
  "wallet_balance": 3.1086
}

Real-Time vs. Cached Data

By default, lookups return cached results (refreshed every 7 days). This keeps costs low and response times fast. If you need live data—for example, checking whether an entity was just filed or dissolved—append ?fresh=true:

curl -X POST https://api.opensosdata.com/v1/lookup \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "state": "ID",
    "query": "NewCorp LLC",
    "fresh": true
  }'

Fresh lookups scrape the Idaho SOS website in real time, ensuring you see same-day filings. The cost remains $0.0314 per lookup.

Coverage: 50 States & Territories

Idaho is one of 50+ jurisdictions covered by OpenSOSData. Current coverage includes all 50 US states plus Puerto Rico, the US Virgin Islands, Washington DC, American Samoa, and Oklahoma. If you expand your application geographically, your API integration stays the same—just change the state parameter.

Common Integration Patterns

Batch Lookups

If you have 1,000 entity names to verify, loop through and make 1,000 API calls. At $0.0314 per lookup, your total cost is $31.40—well below the $100–$500 you'd pay for manual verification or a subscription service.

Webhook-Triggered Checks

When a customer signs up on your platform, automatically verify their business registration via the ID Secretary of State API. If the entity is not Active, flag it for review.

Scheduled Syncs

Run a daily or weekly job that re-checks critical entities using cached data. Switch to ?fresh=true monthly for real-time verification.
