Hello,  
I would like to understand how to query metadata onchain.  
Let’s assume I want to query metadata of all WomenVSApe NFT ([Terra Finder](https://finder.terra.money/columbus-4/address/terra139pqfy6armpauyqqhev7tdncs64gs26frj92y3)).  
What kind of Query request I should do?

Hello, you can use [Querier](https://docs.cosmwasm.com/docs/0.16/SEMANTICS/#query-semantics). Here you have an [example of the usage](https://github.com/pylon-protocol/pylon-core-contracts/blob/develop/contracts/pool/src/querier/anchor.rs#L44-L60).

Hey @Tips @kasunOMG - you are able to do this using Flipside Crypto, linked [here.](https://flipsidecrypto.xyz/)

Flipside has NFT metadata tables for Terra, ETH, and Solana, queryable via SQL.

I am still struggling to retrieve NFT meta data information consistent way.

For example consider the below two NFT collections. (I took these information from lunart and terra finder)

```auto
//Hell cats 
contractAddr = "terra1uv9w7aaq6lu2kn0asnvknlcgg2xd5ts57ss7qt"  

//Galactic punks 
contractAddr = "terra103z9cnqm8psy0nyxqtugg6m7xnwvlkqdzm4s4k"

```

I am able to query these contacts to retrieve the number of tokens using follow lines of code.

`terra.wasm.contractQuery(contractAddr, {"num_tokens" :{} }).then( res ={console.log(res.count)})`

But below sample code I wrote to retrieve meta data works only for HellCats contract. Not for the galactic punks.

`terra.wasm.contractQuery(contractAddr, {"nft_info" :{ "token_id" : "1" // I have checked with multiple token ids } }).then( res => { })`

Is there any consistent way I can query the metadata for NFT collections using terra.js (These type of queries can be easily perform for Ethereum, Avalanche, or Solana chains). I must be missing major concept in terra I guess.

The issue with above code is that I assume token id to start from 0 for every collection. Its is not true. I have first query the token ids using “all\_tokens” and then use those token ids. The issue was fixed now.
