414  ### Lower-level API
415  
416  We do provide access to the lower-level getter and setters, which are useful if you are storing non-JSON or binary data, need to stream in your response or request data, or do anything else lower-level.
417  
418  - \`async get(key: string)\`: Retrieves a blob for a given key.
419  - \`async set(key: string, value: string | BodyInit)\`: Sets the blob value for a given key. See [BodyInit](https://deno.land/api@v1.38.1?s=BodyInit).
