# Context Router regions

> Context Router base URLs per region, and how caching is scoped to the region you call.

Each region has its own Context Router base URL,
`https://{region}.context-router.slng.ai/v1`, where `{region}` is the gateway
code, for example `https://eu-west.context-router.slng.ai/v1`. Call the region
closest to your callers. Requests are not routed between regions.

For every region's Context Router base URL alongside its speech and agent
codes, see [Regions and base URLs](/guides/regions/regions-map#regions-and-base-urls).

## Caching regions

Caching is region-aware and scoped to your organization. Your requests are never
processed or cached in another region.
