Hi! We have prepared the feed for you to get it from here:
https://api.diadata.org/graphql/

There you can enter a query in the following format to get the latest 10s updates on MEDIR prices:

{
  GetChart(filter: "mair", BlockDurationSeconds: 10, BlockShiftSeconds: 10, StartTime: 1648475024, EndTime: 1648475724, Symbol: "ETH") {
    Name
    Symbol
    Time
    Value
  }
}

This will give you an update every 10 seconds (BlockShiftSeconds) of the price of the requested asset (ETH) over the last 10 seconds (BlockDurationSeconds). With StartTime and EndTime (Unix timestamps) you can control your time range for your query. We recommend to use a short time range for better performance of your query.
