PostalPinCode vs WhatPulse
PostalPinCode.in mirrors India Post's PIN code directory as a simple keyless REST API, returning post-office name, branch type, delivery status, and district/state/circle hierarchy for any 6-digit PIN or by post-office branch name. Responses are plain JSON with no signup, rate-limit tier, or API key required. It's run as a free public-data convenience layer rather than a commercial product.
WhatPulse is a desktop client that measures keystrokes, mouse clicks, and application usage, publishing the results through a companion Web API for personal dashboards and community leaderboards. Every request now needs a Bearer-token personal API key created on the account's API settings page — the desktop client works without one, but the Web API no longer does. Core statistics are free to query; a Premium subscription unlocks deeper productivity insights and unlimited history.
