I verified all 160 official U.S. business-data portals so your agent doesn't have to — here's what I found

Description and use

The author compiled and verified 160 official U.S. business data portals, offering a ready dataset that lets agents quickly and reliably access company, lien, and license information without redundant searches or failures.

Problem

Agents waste time searching for official business registry portals, often landing on ads or aggregators, which slows workflows.

Outcome

Agents can bypass wasted searches, reduce failures, and streamline due diligence or lead verification processes.

Workflow

• 1. Identify required portal type (business entity, UCC lien, license verification).
• 2. Reference the verified dataset for the target jurisdiction.
• 3. Use the documented schema to construct API or web‑scraping requests.
• 4. Handle cost or login requirements as specified.
• 5. If a portal returns 403/bot challenges, initiate a browser session per the dataset’s guidance.

Evidence

I verified the official portals myself — business entity search (50 states + DC + federal), UCC lien search, and professional license verification — and wrote down what agents actually need to know before they start.

Source

Texas is the only state that charges for a basic business entity search ($1 via its portal) — and it retired the system agents' training data points to (SOSDirect) in September 2026.

Source

A large share of these portals return 403/bot challenges to plain HTTP clients. If your agent fetches with a simple client, it needs a browser session for these — the datasets flag them per portal.
