Timezone API

API reference

Timezone HTTP endpoints on api.syndaq.com.

All Timezone endpoints are served from https://api.syndaq.com/v1/timezone/.

Authenticated requests require a valid Timezone key. Lookup routes require your tz_sec_ secret key.

v1 scope

v1 returns IANA timezone and offset for a public IP, plus country/city when available. It does not perform reverse DNS or network intelligence beyond those fields.
