NFT Mint

Minting an ERC721 NFT

This example mints a new ERC721 NFT and sends it directly to the specified user.

cURL

curl -X POST https://api.3mint.io/api/v1/mint   
   -H "Content-Type: application/json"
   -H "X-API-KEY: [YOUR_API_KEY]"
   -d '{"chain": "polygon",
         "network": "mainnet",
         "type": "erc721",
         "to": "0x958fb436dB50DB2F689C364712113cc226b38151",
         "contractAddress": "0x552a43cb61bc127d81b1f280bc39f62e5a51c0c2",
         "quantity": 1 // How many NFTs should be minted -- must be positive integer 
       }'

Axios (JS)

import axios from 'axios';

// replace with your 3mint api key
const apiKey = 'demo';
const url = 'https://api.3mint.io/api/v1/mint';

var requestOptions = {
  method: 'POST',
  url: `${url}`,
  headers: {
    'Content-Type': 'application/json',
    'X-API-KEY': `${apiKey}`
  },
  data: {
