Thanks for making this great tool and sharing it for everyone :)

Can I ask you few questions?

On this tool,
https://helloacm.com/tools/steemit/delegators/
Do you use SteemSQL to get the data?

And it seems this JSON API https://uploadbeta.com/api/steemit/delegators/?cached&id=justyy
doesn't work atm (returns 503 error)

I found your site uses a different API end point
https://helloacm.com/api/steemit/delegators/?id=steemhunt&hash=c97ba81f0c01af3cb9ff622648330813
like this..

Is it okay if I use that API?
And what's the hash parameter? (it returns 503 as well without hash param)

Oh btw, I build a sub community on Steem called Steemhunt and we need this API to make our sponsor page, but I thought I should ask you a permission first.
I would cache the result, so the number of calls would not be that many (maybe 1 / hour)
