AL Secretary of State API: Business Entity Lookups

AL Secretary of State API: Real-Time Business Entity Lookups

The Alabama Secretary of State maintains comprehensive records on every registered business entity in the state. If you need programmatic access to this data—whether you're building compliance tools, conducting due diligence, or verifying business information—an AL secretary of state API eliminates manual searching and spreadsheet work.

OpenSOSData provides a REST API that connects directly to Alabama's business entity records, returning structured data in seconds. This guide covers how the API works, pricing, what data you get back, and how to get started.

Why You Need an AL Secretary of State API

The Alabama Secretary of State's public records portal is useful for one-off searches, but it's not built for scale. If you need to:

Verify business registration status programmatically
Retrieve officer names and registered agent details
Extract formation dates and entity types
Automate compliance checks across multiple entities
Integrate business data into your application

...then a dedicated API is the right solution. Manual lookups cost time; an API costs $0.0314 per lookup.

What Data Does the API Return?

Each successful lookup returns:

Entity name (exact legal name as registered)
Entity type (LLC, Corporation, Partnership, etc.)
Entity ID (Alabama's internal identifier)
Status (Active, Dissolved, Inactive)
Formation date (when entity was registered)
Registered agent name and address (service of process recipient)
Principal address (business location)
Officers (names and titles, when available)

All data is returned as JSON, ready for your application.

Pricing: $0.0314 Per Lookup (Pi Pricing)

OpenSOSData uses irrational pricing: $0.0314 per lookup. This is intentionally tied to Pi—fundamental, infinite, mathematical.

Cost structure:

No monthly subscription
No seats, no limits on requests per day
Pay only for lookups you make
Minimum wallet: $3.14 (funds 100 lookups)
Cache hits are free (7-day Redis cache)
Use ?fresh=true to force real-time scrape (charged as normal lookup)

For comparison: OpenCorporates charges $0.10–$0.50 per lookup. Cobalt Intelligence charges $0.50–$2.00. Middesk charges $1.00+. OpenSOSData's $0.0314 pricing is the lowest in the market.

How Caching Saves You Money

OpenSOSData caches all lookups for 7 days using Redis. If you query the same entity twice within 7 days, the second lookup is free. Your application only pays when fresh data is needed.

This is particularly valuable for:

Background checks that run daily or weekly
Compliance monitoring across your customer base
Batch processes that query the same entities multiple times

For real-time data (ignoring cache), append ?fresh=true to your request.

Which States Are Supported?

OpenSOSData currently covers 17 US states:

NV, DE, AR, TX, CO, IA, KY, GA, NH, OH, MN, ND, WI, ID, AL, NC, FL

Alabama (AL) is fully supported.
