# AWS::BedrockAgentCore::RuntimeEndpoint
<a name="aws-resource-bedrockagentcore-runtimeendpoint"></a>

AgentCore Runtime is a secure, serverless runtime purpose-built for deploying and scaling dynamic AI agents and tools using any open-source framework including LangGraph, CrewAI, and Strands Agents, any protocol, and any model.

For more information about using agent runtime endpoints in Amazon Bedrock AgentCore, see [AgentCore Runtime versioning and endpoints](https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/agent-runtime-versioning.html).

See the **Properties** section below for descriptions of both the required and optional properties.

## Return values
<a name="aws-resource-bedrockagentcore-runtimeendpoint-return-values"></a>

### Ref
<a name="aws-resource-bedrockagentcore-runtimeendpoint-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the ARN of the runtime endpoint. For example:

 `arn:aws:bedrock-agentcore:us-east-1:123456789012:runtime/MyRuntime-a1b2c3d4e5/runtime-endpoint/MyEndpoint-f6g7h8i9j0` 

For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).

### Fn::GetAtt
