# SpeedToLead Board > Free, opt-in self-test and public leaderboard of how fast construction and home-service contractors respond to new leads. Built by Builder Clarity (https://builderclarity.com). Key facts: - Grades: A = reply within 5 minutes, B = within 15 minutes, C = within 1 hour, D = within 24 hours, F = slower or no reply. - Only companies that sign up and test themselves are listed. No robocalls, no call recording, no fake form fills. - Contractors start the timer; detected replies stop it automatically. Calls count after they end, including processing delay. Manual stops are labeled self-reported. Auto-timed does not prove a human responded. Rows marked "example" are placeholder data, not real companies. - Industry context: Valve+Meter tested 466 home-service companies; 95% did not respond within 5 minutes and 40% never responded (https://marketing.valveandmeter.com/speed-to-lead-home-services/). ## Pages - [Home, how it works, FAQ, methodology](https://speedtoleadboard.com/) - [Leaderboard](https://speedtoleadboard.com/leaderboard) - Trade/city rankings: https://speedtoleadboard.com/{trade}/{city}, e.g. https://speedtoleadboard.com/roofing/dallas-tx ## Data - [Leaderboard JSON (CORS-enabled)](https://speedtoleadboard.com/api/leaderboard?trade=Roofing&city=Dallas%2C%20TX): fields company, trade, city, seconds, grade, example - [Aggregate stats JSON](https://speedtoleadboard.com/api/stats) ## Agent tools (WebMCP) Pages register navigator.modelContext tools when supported: start_speed_test, get_score, search_leaderboard, subscribe_newsletter.
