How to get an OpenSea API Key in 2022 — Full Guide

As a back-end developer, have you encountered this: submitted an OpenSea API Key application a few months ago and haven’t heard back yet?

In this article, we will explore the most recent way to obtain an OpenSea API Key, and describe how to apply solutions other than the OpenSea API Key to easily build projects that require NFT data.

Let’s get started!

TL;DR

1. The OpenSea API is one of the most critical infrastructures in the NFT industry now, as many other services need/want to access it to obtain NFT data. However, the application process for its API Key is strict and slow, thus severely limiting the efficiency of developers currently building in the ecosystem. In addition, the OpenSea API has strict restrictions on speed;
2. Contrary to what most people think, obtaining an OpenSea API Key is not extremely difficult. The popular misunderstanding that an OpeaSea API Key is hard to get largely comes from the complaints expressed by the majority of applicants. Many of them fail the application because they are not working on legit and promising projects that OpenSea wants to support;
3. In fact, if you have a real and reliable project, applying for an OpenSea API Key is relatively simple and easy;
4. In addition to the OpenSea API, developers can also use the Chainbase NFT API to execute the interaction with NFT data in the blockchain world.

Background

As Non-Fungible Tokens (NFTs) popularize, more and more developers start to build NFT-related projects. However, many developers have encountered problems while obtaining OpenSea APIs.

Applying for an OpenSea API Key is difficult and time-consuming due to its high threshold and slow processing. Moreover, the restrictions on the speed of API requests further limit the productivity of developers.

How to get an OpenSea API Key

Many developers have trouble applying for an OpenSea API Key, which is mostly because their projects fail to meet the OpenSea standard. If you have already built a prototype (an existing product is better) and can demonstrate that you are working on a legit and promising project during the application process, the chance of getting your API Key request approved will significantly increase.

In order to get the approval of an OpenSea API Key, you need to perform the following three steps:

1. Open up the OpenSea API Key Request Form

2. Fill out the form (describe your project carefully), accept the terms of services, and submit

3. Once the API request is approved, you will receive a confirmation email

Yes, it’s that simple.

Reminder:

• Do not apply in the name of using Bot, because Bot does not create values for the ecosystem, so the application is likely to be rejected.
• Do not buy OpenSea API Keys from scalpers. Usually, they will cheat you out of your money.
• The review process generally takes two business days and you will be notified via email once it is completed.

An alternative to the OpenSea API Key

Fortunately, there is an alternative to the OpenSea API Key. In essence, Chainbase provides developers with a better solution to query NFT data without relying on the OpenSea API Key.

Using the Chainbase NFT API, developers can interact with the data from NFT platforms like OpenSea, X2Y2, and Looksrare (more to come). Based on this functionality, they can build a variety of NFT applications, such as NFT Marketplace, NFT Dashboard for data analysis, NFT-Wallet integration, etc.

What you need to do is quite simple: sign up for a free Chainbase account, create a project to obtain an API Key, and follow the dev documentation to get started.

Below we will introduce how easy it is to use the Chainbase NFT API via a code walkthrough.

In fact, Chainbase has a lot of useful APIs in addition to the listed demos. Even in cases where the requirements are not met, developers can quickly query data by generating custom APIs directly in Data Cloud via SQL.

Data Cloud is an online data warehousing service for Web3 developers with unified management. It provides back-end data capabilities for querying, extracting, and analyzing data from multiple blockchain networks. Learn more about Data Cloud
