Glad you like it. Here is a list of blockchain fields that we currently index:

• permlink
• total_payout_value
• created
• title
• children
• net_votes
• body
• parent_permlink
• tags
• author
• json_metadata (as meta)

If you need some other field not listed for a specific application please contact me on Steemit.chat and we can figure it out. Also, I apologize for the delay I have not had a chance to check steemit until now.
