Hey, thanks for opening #407 and #393. I will review, add tests and merge this in soon.

Just to let you know the direction of this project, we are building 2 APIs concurrently. as part of BirthdayResearch/jellyfishsdk#580 and Rust node move. We are separating and moving more indexing responsibilities to jellyfish.

The current API (this project) will be a full node compatible build and will still be worked on.

We are also working on another API that doesn't rely on defid, this new API which is in planning now will resolve the mountain of issues we face while building this API namely https://github.com/DeFiCh/whale/issues/50 and https://github.com/DeFiCh/whale/issues/51. This move is necessary to resolve the technical debt we accumulated in the early days that bring out Ocean API fast.
