Quick Start

The Underdog API allows you to mint, manage, and update your NFTs all-in-one place. We support compressed NFTs built on Metaplex's Bubblegum Program out-of-the-box.

Configuration

To get started with the Underdog API, you'll need to set up two pieces of configuration.

  • Underdog API Endpoint
  • API Key

Underdog API Endpoint

The Underdog API has two endpoints that connect to either Solana Mainnet or Solana Devnet.

NetworkAPI Endpoint
Solana Mainnethttps://mainnet.underdogprotocol.com
Solana Devnethttps://devnet.underdogprotocol.com

For this example, we'll be using the Solana Devnet API endpoint because the Solana Mainnet API requires activating a paid Underdog plan.

const underdogApiEndpoint = "https://devnet.underdogprotocol.com";

API Key

You can get your API Key from https://app.underdogprotocol.com/apikeys.

const config = {
    headers: { Authorization: `Bearer ${UNDERDOG_API_KEY}` }
};

Create a Project

Finally, some on-chain interaction. Once you have your configuration set up, you can Create a Project which handles creating the collection NFT, securing it in a secure vault, and making sure all your NFTs are verified as part of the collection.

const projectData = { 
  "name": "Underdog Project", 
  "symbol": "UP", 
  "image": "https://i.imgur.com/jMHjy8x.jpeg" 
};

const createProjectResponse = await axios.post(
  `${underdogApiEndpoint}/v2/projects`, 
  projectData, 
  config,
);

Create an NFT

Time to Create an NFT. You can grab the Project's ID from the API response, a human-readable identifier for your Project and then pass in the metadata for your NFT.

const nftData = { 
  "name": "Underdog #1", 
  "symbol": "UP", 
  "image": "https://i.imgur.com/Wch6qLE.png", 
};

const createNftResponse = await axios.post(
  `${underdogApiEndpoint}/v2/projects/${createProjectResponse.data.projectId}/nfts`, 
  nftData,
  config,
);

Full Code

Want to just copy-paste the full code and run it yourself?

import axios from "axios";

const underdogApiEndpoint = "https://devnet.underdogprotocol.com";

const config = {
    headers: { Authorization: `Bearer ${UNDERDOG_API_KEY}` }
};

const projectData = { 
  "name": "Underdog Project", 
  "symbol": "UP", 
  "image": "https://i.imgur.com/Wch6qLE.png", 
};

const createProjectResponse = await axios.post(
  `${underdogApiEndpoint}/v2/projects`, 
  projectData, 
  config,
);

const nftData = { 
  "name": "Underdog #1", 
  "symbol": "UP", 
  "image": "https://i.imgur.com/Wch6qLE.png", 
};

const createNftResponse = await axios.post(
  `${underdogApiEndpoint}/v2/projects/${createProjectResponse.data.projectId}/nfts`, 
  nftData,
  config,
);
