Preamble

Date parameters are represented as YYYY-MM-DDThh:mm:ss or YYYY-MM-DD. The timezone is UTC. Durations are represented by concatenating the number of time units and the time unit it represents (for example '1year', '3months', etc..). Available time units are: minute, hour, day, week and year.

Charts API Get the data behind Blockchain's charts

Method: GET
Example: https://api.blockchain.info/charts/transactions-per-second?timespan=5weeks&rollingAverage=8hours&format=json

$timespan Duration of the chart, default is 1 year for most charts, 1 week for mempool charts. (Optional)
$rollingAverage Duration over which the data should be averaged. (Optional)
$start Datetime at which to start the chart. (Optional)
