Get Total Supply of an Asset

arrajput

Hey Guys,

I have a small requirement that I need to fulfill without digging into the gory details. I need to get the "Total Supply" of an Asset from Stellar via an API call. All I need is the "Total Supply" from here

Here is an example,

https://stellar.expert/explorer/public/asset/TFT-GBOVQKJYHXRR3DX6NOX2RRYFRCUMSADGDESTDNBDS6CDVLGVESRTAC47-1

This is what it returns,

You can get it with a call to Horizon. Look at this API example:

https://www.stellar.org/developers/horizon/reference/endpoints/assets-all.html

Here is an example query using Satoshipay's Horizon server: https://stellar-horizon.satoshipay.io/assets?asset_code=TFT&asset_issuer=GBOVQKJYHXRR3DX6NOX2RRYFRCUMSADGDESTDNBDS6CDVLGVESRTAC47

The amount field should represent the total supply for this asset.

You could use also a language specific SDK, there are a few available (JavaScript, Java, Go, ...).

Thanks, I will try that

@"bkolobara"#5 Thanks, that worked like a charm !

Last thing, how can I get the price as that call doesn't return the price ?

There is no simple method of getting "the price", because the price can mean many things.

If you define the price as the last traded price, you will need to decide what's the other currency you are trading against (e.g. TFT & XLM, TFT & USD, ...). You then can fetch the last trade from the currency pair with this endpoint: https://www.stellar.org/developers/horizon/reference/endpoints/trades.html. Another option would be to do an average of multiple currency pairs to get the most accurate representation. Or the average of a certain time period, like the price in the last 1 hour.

Another option would be to look at the current order book for the currency pair and extract the price using the ask and bid price: https://www.stellar.org/developers/horizon/reference/endpoints/offers.html. Again, you can interpret this information in different ways, depending on your needs.

Without going into too much complexity, is it possible to retrieve the "current price" in USD as below with a simple API call ?

beno

I'm not sure how the current price is calculated on stellar.expert. And I'm also not aware of any service exposing this information in USD directly.
