Baselayer

Verify US businesses and retrieve KYB data: officers, registrations, risk scores.

Baselayer is a Know Your Business (KYB) platform that verifies US entities against authoritative registration and risk data. It resolves a business by name and address and returns the full profile: officers, state registrations, entity structure, and verification status.

Use it for

• KYB onboarding and vendor/customer verification.
• Due diligence on officers, registrations, and entity structure.
• Screening businesses for risk and watchlist hits.

Pricing

Baselayer bills per order, and the rate depends on the operation and its parameters:

Operation	Price
Business search	$1.00 / search
Business lookup / officers / registrations / officer reverse lookup	Free (reads of a prior search)
Lien search	$2.00 / state searched
Litigation search	$1.00 / category (litigation, bankruptcy)
Watchlist screen	$0.10 – $0.25 / list requested
Industry classification	$0.35 / call
Website analysis	$0.35 / call
Web presence	$0.15 – $0.35 / selected analysis
International business search	$4.00 / search

Parameter choices change the price: a lien search across two states costs $4.00, a watchlist screen of all six supported lists costs $1.35, and a web presence call is the sum of the analyses you select (or of Baselayer’s default set — NAICS prediction and website analysis — when you select none).
