GraphQL

When reading data, you retrieve data that has already been written onto the blockchain and work with the data to display it in some way. This usually involves reading data from a JSON source. Liminal.market has already setup an index on TheGraph, to simplify the process for you.

You can play with the data in TheGraph playground. There you have ready-made templates.

Here is a simple example of Javascript code that pulls the data

GraphQL

let  url = 'https://api.thegraph.com/subgraphs/name/liminal-market/liminal-market-mumbai';

let  query = { query:  'query { liminalMarketInfos { txCount, walletCount, value }}'};
let  request = await  fetch(url, {
	method:  'POST',
	headers: { 'Content-Type':  'application/json' },
	body:  JSON.stringify(query)
});

let  result = await  request.json();
let  data = result.data.liminalMarketInfos[0];
  
//data from response
let  walletCount = data.walletCount;
let  txCount = data.txCount;
let  value = data.value;
