If you've ever needed to verify a business entity, check corporate filings, or pull registered agent information, you know the pain: each state has its own Secretary of State portal, its own search interface, and its own data format.

I built a unified API that queries 18 state SOS databases with a single call. Here's how to use it.

The Problem

Business verification workflows typically require:

Navigating to each state's SOS website manually

Dealing with different search interfaces (some require exact names, others support partial)

Parsing inconsistent result formats

Handling CAPTCHAs, rate limits, and downtime

This is tedious for one lookup and impossible at scale.

The Solution

The US Business Entity Search actor on Apify queries Secretary of State databases across 18 states with a single API call.

Supported States

AK, AR, CO, CT, FL, GA, IA, ID, IN, KY, ME, MO, NE, NM, OH, SD, TX, WY

Python Example

from apify_client import ApifyClient

client = ApifyClient ( " YOUR_APIFY_TOKEN " )
