Mapbox vs PostalPinCode

Mapbox is a location-data platform offering Directions, Geocoding, Maps, and related APIs for turn-by-turn routing, address search, and interactive map rendering. Its endpoints are built for direct browser use — authenticated with an access_token query parameter and served with CORS enabled — rather than requiring a server-side proxy. A generous free tier covers most hobby and prototype usage, with pay-as-you-go pricing and volume discounts taking over once monthly limits are exceeded.

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.
