Introduction to Crypto APIs

Cryptocurrency APIs are Application Programming Interfaces (APIs) that allow developers to access and integrate cryptocurrency data into their applications. APIs provide access to a variety of data such as prices, transactions, and blockchains. With the help of these APIs, developers can create powerful applications that can interact with the crypto world.

Benefits of Using Crypto APIs

The most obvious benefit of using cryptocurrency APIs is that they provide access to a wealth of data that can be used to build powerful applications. The APIs provide access to real-time data. This data can be used to create applications that can monitor the market, track transactions, and even make predictions about the future of the crypto world.

Another benefit of using cryptocurrency APIs is that they are easy to use and provide a consistent and reliable source of data. The APIs are designed to be user friendly, so developers don’t have to worry about getting bogged down in technical details. The APIs also provide reliable, up-to-date data that can be used to create accurate and reliable applications.

Cryptocurrency APIs can also save developers a lot of time and effort. Instead of having to manually gather data, developers can simply use the APIs and get the data they need. This can save developers a lot of time and effort, allowing them to focus on other aspects of their applications.

Types of Cryptocurrency APIs

There are a variety of cryptocurrency APIs available, each with its own set of features and advantages. The most common types of APIs are:

• Price APIs provide access to real-time price data for a variety of cryptocurrencies. These APIs can be used to monitor the market and make predictions about the future of the crypto world.
• Transaction APIs provide access to data about transactions that have occurred in the blockchain. This data can be used to track transactions and determine the current state of the blockchain.
• Blockchain APIs provide access to the blockchain itself. These APIs are used to interact directly with the blockchain, allowing developers to create applications that can interact with the blockchain.

Token Metrics is proud to launch the "TM Investor Grade" to help investors identify promising long-term investments in the world of cryptocurrency. The grade is comprised of three subsets: 

• The Fundamental Grade
• The Technology Grade, and 
• The Valuation Grade. 

Our statistical analysis and machine learning techniques help calculate these grades. They account for many data points to provide a strong indication of the relative strength of each crypto asset or a project.

The TM Investor Grade is intended for use by investors looking to hold onto investments for a longer period of time, created by combining the Fundamental Grade with the Technology Grade and Valuation Grade.

Fundamental Grade

Fundamental analysis has always been a crucial part of the research process at Token Metrics. Before considering any potential long-term investments, we conduct a thorough fundamental analysis to understand an asset's underlying strengths and weaknesses. Our use of fundamental analysis is how we discovered the promising investment opportunity in Helium back in 2018.

However, manually performing fundamental analysis on every token in the market is not feasible. This is why our research and data science teams automated the process. The result is our Automated Long-term Investor Grade. This grade considers a wide range of data points and applies statistical analysis to provide scores in various categories, including valuation, investors, tokenomics, community, and more. 

Technology Grade

Token Metrics is also known for conducting code reviews on cryptocurrency projects. This is how we discovered that MATIC was a particularly strong project. Similar to fundamental analysis, our blockchain engineers carried out these reviews manually. However, we have now automated the entire process. Using open source data, we are able to provide technology scores for nearly all crypto assets. This is extremely valuable for investors, as it allows them to assess the long-term security and feasibility of different investments. Our technology scoring is based on three main categories: development activity, security and audit, and code quality.

The development activity category takes into account the contributions of the development community and tracks various community metrics. The security and audit category looks at the security of a project and tries to determine its resilience to hacks and other vulnerabilities. The code quality category measures how well the project's code is written, by evaluating the number of bugs and violations it has and how well it adheres to best coding practices and standards.

We are thrilled that our data science team, in collaboration with our engineering team, has been able to use statistical analysis to scale up our powerful technology scoring to cover almost all assets in the market.

Valuation Grade

The valuation grade compares a project's fully diluted value, or FDV, with the average FDV of different sectors that project belongs to.

Consider this example:

• CRV belongs to sector A and B
• CRV's FDV = 10
• Average FDV in sector A = 20
• Average FDV in sector B = 50
  

This will show a high valuation grade because the project is undervalued compared to its sectors.

By combining these grades, we get the TM Investor Grade which is much more powerful in determining the strength of the project in the long run.

How To Access

To view the Investor Grade, you can go to the individual token details page. Click on the 'Investor' tab on the left of the screen, and then click on the 'Fundamentals' tab. Then, you will be able to see how the asset is performing in each of the 9 categories we use . All these categories are combined to create the overall Fundamental grade. To generate this grade, we use a wide variety of data sources to gather all the necessary information.

In the same tab, you will find the 'Technology' grade. This grade comprises many different data points. These data points combine into three major categories:

• Development Activity
• Security and Audit, and 
• Code Quality.

You can also access the newly-launched feature on the Rating page by pressing the Investor switch next to Trader. This will help you sort all crypto assets by our Long-term Investor Grade.

If you look at the Ratings page - sorted by Investor Grade in descending order [highest to lowest] - these are assets that Token Metrics believes have strong potential in the future.

The TM Investor Grade is a powerful tool for evaluating the long-term potential of cryptocurrency projects. By considering various data points, including fundamental analysis, technology scoring, and valuation grades, the grade provides a comprehensive assessment of a project's strengths and weaknesses.

The grade updates regularly to reflect changing market conditions, making it an essential tool for anyone looking to invest in the cryptocurrency space.

FAQs

1. How does the Investor Grade differ from the Trader Grade?

The Investor Grade is intended for long-term investing, while the Trader Grade is geared toward short-term trading. The data points used to calculate the Investor Grade differ from those used for the Trader Grade.

2. Which grade should I pay more attention to - the Investor Grade or Trader Grade?

If you are interested in short-term trades based on price action, such as swing or day trades, you should consider the Trader Grade. On the other hand, the Investor Grade is more suitable for customers who want to invest long-term and hold on to their assets for the potential of significant returns or to discover undervalued assets.

NFT marketplaces work by connecting buyers and sellers of digital artwork. Buyers can browse through the different artworks available, and then purchase the artwork they like. The artwork is stored on the blockchain, and the buyer receives a unique token that represents the artwork. This token can then be used to buy, sell, or trade the artwork.

When a buyer purchases an artwork, the money goes to the artist who created the artwork. The marketplace then takes a small commission for facilitating the transaction. The commission varies from marketplace to marketplace, but usually, it is around 5-10%.

The artwork is stored on the blockchain, and the buyer receives a unique token that represents the artwork. This token can then be used to buy, sell, or trade the artwork. The token can also be used as a form of digital currency and can be exchanged for other digital assets like cryptocurrencies.
