Knowing all about OpenSea if you are immersed in the world of blockchain and cryptocurrencies is a must. It is the largest NFT marketplace in the world. It hosts a vast number of global NFT. It also provides critical API infrastructure.

When it comes to the API, OpenSea has the most important one as people can access reliable data of NFT token contracts and metadata. 

What is OpeanSea API and what is it used for?

OpenSea API allows users to explore, find and obtain information about smart contracts and NFT projects placed on the Ethereum blockchain via code. It also allows developers to integrate NFT data into their platforms. 

This is done by enabling the search of cached data through different endpoints using the asset contract address and token IDs. 

API OpenSea: The different data tokens

four different data tokens has OpenSea Developer API  which are the following: 

  • Account Mode: Includes wallet addresses + username.
  • Collection Model: It offers information on all assets for a given contract address.
  • Event Model: state changes for assets-
  • Asset Model: includes individual NFTs. 

It must be noticed that OpenSea is open, free, and read-only, meaning it was created with the purpose of fetching data to display it elsewhere.  

OpenSea API Key: Why is it important to have one? 

The key of OpenSea API represents the identity of the application or the user. It is a unique and random and non-guessable code.

An example of an API key could be: 1IRUHFNV7HbdjAMaHYiE5tRf-Ayu56EEqbe

If you want to access the OpenSea API database you will need this key and all its features and tools. As mentioned before, OpenSea is the largest NFT marketplace meaning that if you get access to this platform you could create your NFT platform and build prosperous investments.

How to get the Open Sea API key?

As seen in the previous section, if you are currently working (or looking forward to working) on an NFT project, getting OpenSea keys could be quite useful. In order to request an API key you can consider the following steps:

  • Step 1: Have a prototype of your product before getting yourself involved with the paperwork that follows. This way you can demonstrate your project is legitimate and not an application that is going to serve as a Bot. If they consider this to be the case, your project will be rejected or ignored. 
  • Step 2: Go to the OpenSea API Request Form and read all the requirements you must have to get the key and proceed to click ‘’next’’.
  • Step 3: You need to fill out the form by providing information and answering some questions regarding your NFT project. Amongst these information that you will need to give are: your email address, project name, discord username, project description, project profile link, and wallet address. 
  • Step 4: Submit the previous answers, read the terms and conditions, and accept them. Once this is done, your application will be in process and awaiting approval.

The process of applying for an Open Sean API key is not difficult. However, OpenSea is in high demand and growing every day with the popularity of non-fungible tokens (NFTs) and the Ethereum blockchain. This is why it is possible that the ‘5-day turnaround time’ is converted into weeks of waiting. If you have patience, you should be fine. Alternatively, you can use other NFT platforms.
