# Reverse Geocoding API Reference

`POST https://staging.eko.in/ekoapi/v3/tools/kyc/reverse-geocoding`

Convert latitude and longitude coordinates into structured Indian address data including locality, city, state, PIN code, and country.

The Reverse Geocoding API translates GPS coordinates into a human-readable, structured address. It is designed for address validation during onboarding, geo-compliance checks, field-agent location verification, and location-based fraud detection workflows. Pass a latitude/longitude pair and receive a normalised address broken down by locality, city, district, state, PIN code, and country — along with a confidence score.
