Typing Speed API
Measure typing speed and accuracy. Compute words-per-minute, characters-per-minute and accuracy from a character (or word) count and the elapsed time, optionally subtracting uncorrected errors for a net WPM; compare what was typed against a reference text to count per-character mistakes and score the attempt; and estimate how long a given amount of text will take at a target speed. Uses the standard typing convention that one word equals five characters. Perfect for typing tests and games, coding-speed tools, onboarding and skills assessments, and leaderboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. A focused typing calculator, distinct from general unit or percentage maths.
