Use the LangCache API on Redis Cloud

You can use the LangCache API and SDK from your client app to store and retrieve LLM, RAG, or agent responses.

To access the LangCache API, you need:

• LangCache API base URL
• LangCache service API key
• Cache ID

For LangCache on Redis Cloud, the base URL and cache ID are available in the LangCache service's Configuration page in the Connectivity section.

The LangCache API key is only available immediately after you create the LangCache service. If you lost this value, you will need to replace the service API key to be able to use the LangCache API.

When you call the API, you need to pass the LangCache API key in the Authorization header as a Bearer token and the Cache ID as the cacheId path parameter.

See the LangCache API and SDK examples for more information on how to use the LangCache API.
