API Domains

Choose the right domain for your integration.

api-bdc.net Recommended

For:: All API endpoints with an API key
Note:: Dual-stack (IPv4 + IPv6), works for all new integrations

https://api-bdc.net/data/ip-geolocation?ip=1.1.1.1&key=YOUR_KEY

api.bigdatacloud.net Free Client-Side

For:: Free client-side endpoints ONLY (no API key required)
Note:: Designed for use directly in the browser or mobile app

https://api.bigdatacloud.net/data/reverse-geocode-client?latitude=-34.9&longitude=138.6

Important: We are not currently enforcing domain separation, but we strongly recommend using the correct domain for all new integrations. This ensures future compatibility as we plan to enforce domain rules in a future update.
