As mentioned by cschilling in cl/3563 there are some other josh endpoints that could be exposed on code.tvl.fyi:
/~/graphql/... A GraphQL API to introspect the repo without cloning it. /~/graphiql/... A UI to test out graphql queries and look at auto generated API reference. /~/browse/... (and some more) A (very much work in progess) repo browser.
We might want to evaluate which ones of these could be interesting to us. I think a third repo browser is not that useful for now, but having an API to the repo is interesting.
