# Regions and data

Three regions, one address. Your request goes to the nearest region by DNS; every region runs the whole stack.
| region | address | when to pin it |
|---|---|---|
| Europe | `eu-gate.crawl4ai.com` | `api.crawl4ai.com` picks the nearest region for you. Pin a region when the page you fetch answers differently per country, or when your data must stay in one region. |
| Singapore | `sin-gate.crawl4ai.com` |  |
| United States | `us-gate.crawl4ai.com` |  |

> **Note**
>
> What we keep: every request's parameters and result summary for 90 days, so your usage history and our reliability work have the facts; the pages we fetch for you sit in our cache so a repeat is instant. We never sell or share what you fetch. Your API key is shown once in the dashboard and can be regenerated at any time.
