# Use Case 4: Non-Organization-Owned API Exposed to a Non-Organization-Owned API Consumer

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Use case four has one pattern that supports the scenario in which a non-organization API is exposed
to a non-organization API consumer.

## Pattern 9: Non-Organization External API exposed to a Non-Organization External Consumer

In pattern nine, Omni Gateway acts as an intermediary between two external entities; for example,
when an external customer consumes a travel information service offered by an external airline.

The following diagram shows the physical implementation of a scenario in which a non-organization
external API is exposed to a non-organization external consumer on Kubernetes. The diagram assumes
that the firewall terminates the incoming external mTLS connection.
