Empty response even if mosaics are present under namespace

Tech Support
#1

Hello,

I’m using /namespace/mosaic/definition/page?namespace=namespaceName this API to retrieve all the mosaics under given namespace. But for some of the namespaces, it returns empty even if mosaics are present.

For example,
“namespaceId”: “imre.g”,
“name”: “tokens”

HTTP Response:
{
“data”: []
}

Why this?

#2

It’s because namespace imre expired.
If namespace will expire all mosaics in it are no longer transferable and balances are removed from accounts.

[SOLVED] Delete mosaic is possible or not
#3

Is there any other way or API to get that information then?
I want to calculate balance deduction from account. And if transaction is of mosaic transfer and levy is configured then levy fee should be deducted from the sender so

#4

In such a case, how explorers are showing this even after deletion?

#5

@CryptoBeliever Can you please help?

In such a case, how explorers are showing this even after deletion?

I think there are two possibilities:

  1. Explorer is using as the source node db (h2 db)
  2. Mosaics definition information is created during loading mosaics transactions

You can try to ask explorer author Explorer.ournem.com - Feedback

Hi,

Is there any way to get the mosaic definitions at a particular block height?

If the mosaic is expired at 100th block height and created again with the same name but a different definition, and if I fetch the information now then it will give me the latest one not the one which was there before the 100th block and this will cause balance mismatch for the <100 blocks.

@CryptoBeliever Could you please help here?

No (afaik). You have do as described here: Mosaic levy fee at a particular blockheight - #2 by CryptoBeliever
