i need a cheap API that can tell me all the mutuals of a given fid
- dune query too expensive
- neynar API no longer works

building this requires an index of the whole follow graph and needs to be kept in sync

Update: best solution is probably reading up to N pages from snapchain’s getLinksByFid?fid/target_fid and then falling back to dune if there are additional pages

And then add some caching

Does the grpc endpoint still give you all links via a function or something? GetLinksByFid & GetLinksByTarget? I think you can specify a very large size and just get all of them, maybe specify the max size for a storage unit and check based on how many storage units the user has? That might cover 90% of cases in one page I guess

Yes you can do 20k messages in a single page in the http api but it’s pretty slow

Protobufs on grpc must be like 1/2-1/4 of that just in the compact bytes down the wire surely instead of json utf8 or whatever I imagine
