# Gridstone
> Gridstone is a local business lead generation product for web design and local SEO agencies. It finds contractor prospects on Google Maps and ranks them by visible website, review, reputation, and contact signals.

Gridstone is a signed-in web application, not a public developer API platform. There is no public REST API, OpenAPI specification, inbound product webhook catalog, or MCP server. Agents should use the machine-readable files and public pages listed below.

Markdown representations of public pages are available at the same URL when the request sends `Accept: text/markdown`, or by appending `.md` (use `/index.md` for the homepage).
