What services or APIs are available to do advanced queries of account state on NEAR Protocol? The most basic is a time series of account balances for a specific account over time, eg:
# for account foo.near
20220731 1.234
20220730 1.567
...
I know Flipside has indexed the chain (docs) and stats.gallery does account-level stuff with charts but I can't find any dashboards that display this on awesomenear.com or good APIs. Any others?
Ideally there are more advanced queries possible as well, of course.
https://pikespeak.ai/ is nice & an API is on their roadmap. It doesn't give you balance on every block but there is CSV export so it can be added in an xls/sheet.
