# OpenLawn

> AI lawn measurement for lawn care and pest control businesses. Enter a customer property address; GPT-6 Astra maps reviewable lawn polygons on aerial imagery with available parcel context. Estimates are reported in square feet to support quoting and service planning, not automated prices or pest treatment instructions.

Official website: https://openlawn.ai/. Updated 2026-09-06. New accounts receive five free completed AI measurements. Account history requires sign-in. Parcel coverage and imagery quality vary. Results are estimates, not legal surveys or independently guaranteed accuracy. Maintained areas outside a parcel do not establish ownership. This file provides documentation, not crawler permissions; see robots.txt.

The public REST API is https://api.openlawn.ai/v1. Documentation needs no login or API key; measurements and workspace records require a scoped key. Keep keys in server-side secrets, never in prompts or browser code. Creating a new completed measurement consumes the key creator's credit; reading existing results does not. OpenLawn offers both a REST API and a browser skill, not a public MCP server.
