LotCheck Pro — full buildability analysis (bring your own Anthropic key)
A frontier-model due-diligence memo that reasons across the data above — terrain, septic,
flood, soils — and is built to be honest: each section names what the data can't tell
you, and the checklist is prioritized by this specific lot's hard points, not a generic form.
Your Anthropic key stays in your browser and is sent only to api.anthropic.com; it never
touches this server. How your key is handled →
New to API keys? What this is and why it's safe
An API key is a secret token (it starts with sk-ant-) that lets a program use Claude on
your own Anthropic account, billed to you per use — here, typically a few cents per analysis.
lotcheck keeps no key of its own, so you bring your own and pay only for what you run. To get one, sign in
to the Anthropic Console at platform.claude.com, add a payment method, and create a key
under Account Settings → API Keys (you can set a monthly spending limit there to cap cost). Paste it
into the key box and run an analysis: it is sent straight from your browser to api.anthropic.com
and is never sent to or stored on lotcheck's server. It is saved only in your own browser, and only if
“Remember key” is ticked — untick that to keep it for this visit only. You stay in control:
revoke or rotate a key anytime in the Console.

Informational only. Not a survey, flood determination, title search, or professional due diligence. Federal flood maps can be out of date or absent — absence of a mapped zone is not a guarantee. Verify flood status via a FEMA LOMA and a licensed surveyor before relying on anything here. County data is sourced from the county's GIS and may lag the authoritative county portal.
