Getting started

This tutorial will help you make your first API call to receive a list of NFT tokens in the CSPR.studio contract.

Prerequisites

We will use cURL to make API calls. You can install it from the curl.se website or by using the package manager of your choice.

Create an access token

Please register on CSPR.build console to create a CSPR.cloud access token.

First API call

To fetch the NFT tokens in the CSPR.studio contract we'll be using the NFT API. The endpoint requires a contract package hash, which we can find on CSPR.live:

curl -X 'GET' \
  'https://api.cspr.cloud/contract-packages/c4e5a03066ce3c6006f562939e48f7076c77de5d46cf8fe625c41e02c5e74814/nft-tokens' \
  -H 'accept: application/json' \
  -H 'authorization: [Your access token]'
