Bitcoin block Explorer API
Queries currently supported:
Delayed stats
These use BBE data.
- eta - shows the estimated number of seconds until the next retarget. The parameter sets how many blocks to look back at (default 1000). Blocks before the last retarget are never taken into account, however.
- getsentbyaddress - shows the total BTC sent by an address. Do not use this unless you know what you are doing: it does not do what you might expect.
- addressbalance - shows received BTC minus sent BTC for an address.
