NFT Data API Overview

The NFT Data API is a GraphQL API that makes it easy to query any NFT data. Instead of spending months of dev work on your own blockchain indexer, integrate our NFT Data API to build any dApp you can imagine.

Getting Started

Get API Key

Request API Key

POST to GraphQL API

Make a HTTP POST request to https://api.indexer.xyz/graphql (opens in a new tab) with these headers

"x-api-key": YOUR_API_KEY,
"x-api-user": YOUR_API_USER

You can make queries to the API using any GraphQL client library or tool.

Example using axios

import axios from "axios"
 
const query = `
  query fetchCollectionInfo($collectionId: uuid!) {
    sui {
      collections(where: { id: { _eq: $collectionId } }) {
        slug
        title
        cover_url
        supply
        verified
      }
    }
  }
`
 
const variables = {
  collectionId: "4827d37b-5574-404f-b030-d26912ad7461"
}
 
const res = await axios({
  url: "https://api.indexer.xyz/graphql",
  method: 'post',
  data: {
    query,
    variables
  },
  headers: {
    "x-api-key": YOUR_API_KEY,
    "x-api-user": YOUR_API_USER
  }
})

Example using graphql-request and graphql-tag

import { GraphQLClient } from "graphql-request"
import gql from "graphql-tag"
 
const query = gql`
  query fetchCollectionInfo($collectionId: uuid!) {
    sui {
      collections(where: { id: { _eq: $collectionId } }) {
        slug
        title
        cover_url
        supply
        verified
      }
    }
  }
  `
 
const variables = {
  collectionId: "4827d37b-5574-404f-b030-d26912ad7461"
}
 
const client = new GraphQLClient("https://api.indexer.xyz/graphql", {
  headers: {
    "x-api-key": YOUR_API_KEY,
    "x-api-user": YOUR_API_USER
  }
})
 
await client.request(query, variables)

💡

These are just a few examples to get you started. There are many libraries and tools for making GraphQL requests. For example you may want to use Apollo GraphQL (opens in a new tab), or Tanstack Query (opens in a new tab) for more robust solutions such as managing cache.

How to Select a Chain

The GraphQL API is divided at the root level into different chains. Simply wrap your query with the chain of your choice to get data from that chain.

query fetchCollectionInfo {
  sui {
    collections {
      id
      slug
      title
      cover_url
      supply
      description
      floor
      volume
    }
  }
}
