Cambodia Exchange REST API

A clean JSON API for daily MEF-published KHR exchange rates. Built for accounting systems, ERPs, spreadsheets, and fintech apps operating in Cambodia.

Quick start

Every request requires a Bearer token in the Authorization header. Generate keys from your dashboard once Pro access is enabled.

curl https://api.cambodiaexchange.today/v1/rates/latest \
  -H "Authorization: Bearer YOUR_API_KEY"

Authentication

API keys are scoped per project. Keep your secret key on the server — never ship it in client-side code. Rotate keys at any time from your account settings; revoked keys stop working immediately.
