Baselayer

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. Attach baselayer to an Exa Agent run through Exa Connect, and the agent queries Baselayer alongside Exa web search.

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).

Example
