Looks good, I would modify the PR description to update it from team Notion to our docs site, and add the Purpose section. Have you tested that it caches correctly?

[camspec]

You can check if the endpoint was cached by looking for the response header or verifying that the endpoint was not run the second time

[LegendaryAKx3]

Updated the description, caching is tested to be working (as shown in screenshot)

I cleaned up your description a bit, LGTM!
