Region and API base URL (EU vs US)
Cludo’s API is available in two regions. Your API base URL depends on which region your account is in.
Base URLs
- EU:
https://api-eu1.cludo.com - US:
https://api-us1.cludo.com
How do I know which region I am in?
Your region is determined by your Customer ID, specifically by its numeric value.
- Customer IDs with a value below 10,000,000 belong to the EU region.
- Customer IDs with a value of 10,000,000 or higher belong to the US region.
In other words, the region depends on how large the number is — which in practice often corresponds to how many digits the Customer ID contains.
If you are unsure which region your setup belongs to, simply compare your Customer ID to the threshold above.
You can find your Customer ID in MyCludo under your account or engine settings.
Why does this matter?
Your credentials (SiteKey or API Key) are tied to your region. EU credentials do not work against the US base URL, and vice versa. Always use the base URL that matches your region when calling search, autocomplete, AI Chat, AI Summary, or any other Cludo API endpoint.
