Getting Started

BigDataCloud is organised into API packages. This guide walks you through choosing the right package, understanding when you need an API key, and creating your account.


Step 1: Choose your package

All BigDataCloud APIs are grouped into packages. Browse the API Reference section in the sidebar to explore what's available, or start with one of these:

Step 2: Do you need an API key?

It depends on which APIs you're using.

Free APIs — no key required

Some APIs are completely free with no authentication needed — just call them directly from the browser or a client-side app. These are under the Free APIs package.

Premium APIs — API key required

All other packages (IP Geolocation, Reverse Geocoding, Phone & Email, Network Engineering) require an API key. A generous free tier is included — no credit card needed to sign up.

Step 3: Create your account

Sign up at bigdatacloud.com — no credit card or sensitive information required. Your API key is created immediately and starts propagating across our servers. Most requests will work within a few minutes.

Your email is your permanent account identifier

Choose carefully — your email address cannot be changed after registration. We recommend using a corporate email address. Disposable email addresses are not accepted.

API key propagation

After your key is issued, it propagates across all our servers automatically. Most requests will work within minutes, but full propagation can take up to 10 minutes. See What is API Key Propagation? for more detail.
