Explorer-backend and frontend help

Okay, I'm new to all this so please bear with me.. I'm setting up the explorer-backend in support of my project. The reason I believe I need it is to take snapshots for airdrops to NFT holders. Problem is now that I've got chain-grabber syncing I'm not sure where I go from here. Do I need to install the explorer-frontend as well? Would anyone be able to explain how to actually take a snapshot of the chain and how I can isolate the wallets that hold NFTs from a specific project?

you don't need to setup your own explorer for this I would just make api requests to track down who holds what

Okay, how would I go about doing that? Total noob here when it comes to this stuff. I've only ever really done server admin type stuff... Ironically I also have a question for you in regard to your bulk minter 😅 Would it be with the Token search function I'm seeing on the api site?

MGpai•4y ago

what is your backend code written in?

No_Rav3nOP•4y ago

I used the explorer-backend repo on github so scala I believe

MGpai•4y ago

no like to call api what language are you using?

No_Rav3nOP•4y ago

Ah, I was following an ergotutorials video to try and figure it was using java

MGpai•4y ago

so you can go to gql https://gql.ergoplatform.com/ and make this query

query Query($tokenId: String) {
  boxes(tokenId: $tokenId) {
    address
  }
}

query Query($tokenId: String) {
  boxes(tokenId: $tokenId) {
    address
  }
}

and you will see all address that held your token

you can also go here

https://api.ergoplatform.com/api/v1/boxes/unspent/byTokenId/{tokenID}

https://api.ergoplatform.com/api/v1/boxes/unspent/byTokenId/{tokenID}

and it will show the box the token is in currently and you can also see address there

Okay, am I able to input multiple token IDs with this?

@MGpai I can't send messages in that channel. I have it set up with multiple queries in one file but they don't all run at the same time. @Sepehr (Simon), do you have an example of what the syntax is to run a batch query?

Sepehr•4y ago

This is one example, you can batch multiple Ids and get all of them in one query.

If this is not the appropriate place for this question let me know. I am working on a website that has to display the balance of several wallets. I didn't know if I needed my own ergo node to do this but I figure it would probably be more reliable if I did. What I want to know is how to request the balance of a wallet from my node?

MGpai•4y ago

use this api https://api.ergoplatform.com/api/v1/addresses/9iKFBBrryPhBYVGDKHuZQW7SuLfuTdUJtTPzecbQ5pQQzD4VykC/balance/confirmed

nopalitos•4y ago

It worked thanks. Is it possible to make the request to my own node?
