 ## Open Inference Protocol / V2 Protocol
 
-**For an inference server to be compliant with this protocol the server must implement the health, metadata, and inference V2 APIs**. Optional features that are explicitly noted are not required. A compliant inference server may choose to implement the HTTP/REST API and/or the GRPC API.
+**For an inference server to be compliant with this protocol the server must implement the health, metadata, and inference V2 APIs**. Optional features that are explicitly noted are not required. A compliant inference server may choose to implement the [HTTP/REST API](#httprest) and/or the [GRPC API](#grpc).
 
 The V2 protocol supports an extension mechanism as a required part of the API, but this document does not propose any specific extensions. Any specific extensions will be proposed separately.
