Beginner’s Introduction to Cryptocurrency APIs: The Basics You Need as an Intern Web Developer

A few months ago, when I first started learning about cryptocurrency, I felt like I was thrown into a whole new world, with people using complex terms that I didn’t understand. One concept in particular that I struggled to grasp was APIs.
It took me hours of tutorials and personal research to finally understand what APIs are and what they do. So if you are a trainee web developer, crypto enthusiast, or new to crypto trading and have a similar problem to mine, then this is the tutorial you will need.
Using simple language and easy-to-understand analogies, by the end of this tutorial you will save hours of research and be able to answer the fundamental questions:
- What are cryptocurrency APIs and how do they work?
- Why are cryptocurrency APIs important?
- What are the main APIs available?
Now let’s get started!
What are cryptocurrency APIs and how do they work?
To understand this, we must first understand what APIs are. API is an acronym that stands for Application Programming Interface.
Sounds complicated? Let’s break it down.
An application is software that helps people get information about specific things or do certain tasks, like the Expedia app on your phone that helps you book flights on the go or the Amazon weather app that helps you check the weather forecast.
An interface in this context is a program that helps 2 apps or websites communicate with each other, kind of like a middleman. So an API is basically a program or a “link” that helps two apps (or websites) “talk” to each other about a particular thing. So when an app (let’s call it app A) needs information about a particular thing or needs to access a service provided by another app B, an API of app B is used.
This API for App B acts as a link, a connection through which the specific information that App A requires is obtained from App B.
Wait what?!
Ok, ok. Let’s break this down further using this analogy:
Imagine you open a bakery and decide to sell cupcakes, muffins, and sourdough bread. However, for some reason, you don’t have the skills to make the sourdough bread yourself.
What are you doing?
You go to another bakery that sells sourdough bread. You make an agreement for them to sell you sourdough bread when you ask for it.
So, whenever you need bread, you go to an employee of that bakery and he brings you the bread.
Now, bread is not the only thing this second bakery sells, but it is the only thing you need from them. This is how an API basically works.
When an app needs information that it can’t provide on its own, it uses another app’s API to access that information from the other app.
For a more technical analogy.
To illustrate how the API works, let’s use a flight booking app:
Imagine using a travel app like Expedia to book a flight. When you search for flights, the app doesn’t have all the flight information stored locally. Instead, it uses specific APIs to fetch data from airline systems or other flight databases.
Here’s basically what happens behind the scenes:
-
The travel app sends a request to the airline’s API (e.g., “Get flights from Nigeria to New York on August 26”).
-
The airline API processes the request and returns the relevant data (e.g. flight numbers, departure times, prices).
-
The travel app receives the data and displays it in an intuitive format.
As you see:
- The travel app is the “client” or “consumer” of the API.
- The airline system is the “provider” of the API.
- The API acts as an intermediary, allowing the travel app to access airline data without having to replicate it locally.
So if I am an app developer and the app I am working on is to provide specific information about Qatar Airways flight schedules, for example, I will use a Qatar Airways API to allow me and my future users to access that information.
Now that we understand what an API is, by directly applying this knowledge, we can say that cryptocurrency APIs are basically programs that allow different apps or websites to access specific cryptocurrency data (e.g. chart updates, transactions, etc.) from other websites that monitor and interact directly with the cryptocurrency market.
So if I want information about the current state of Bitcoin in the cryptocurrency market, I open a website like Dervi.
This website cannot directly monitor the cryptocurrency market, so it uses an API to get information about the current status of Bitcoin from the Trading View website.
Why are cryptocurrency APIs important?
From the above, we can say that some of the most important APIs for cryptocurrencies are:
-
Real-time data access: APIs provide up-to-date information on market prices, trading volumes, and blockchain data, enabling informed decisions.
-
Research and Analysis: APIs provide data to researchers, analysts, and investors to study market trends and make predictions.
-
Integration with other services: APIs enable integration with payment systems, e-commerce platforms, and other services, broadening cryptocurrency adoption.
In essence, cryptocurrency APIs facilitate innovation, automation, and accessibility in the cryptocurrency and blockchain ecosystem.
What are the main cryptocurrency APIs?
Now that we understand what APIs are and why they are so important, let’s take a look at some of the major cryptocurrency APIs:
Coin Market Cap API
Coin Market Cap is one of the best cryptocurrency data APIs. So as a developer, embedding it in your app or website will be really helpful. You see, it offers real-time cryptocurrency data and market information, such as:
- Historical Cryptocurrency Data Since 2013
- Real-time price updates for cryptocurrencies
- Market data, volume and trading information
- Trading data and analysis
- Non-Fungible Token (NFT) Data Business, Professional and Free API Plans
This is an API used worldwide by cryptocurrency traders, developers, and financial companies.
CoinGeko API
CoinGeko is a big name among web developers! It offers many exciting features and has an easy to use interface. It has its own charts that it uses to track different coins in the cryptocurrency market. Some of the important features that it offers are:
- Real-time and historical cryptocurrency prices,
- Market capitalization data,
- Trading volume and trading data,
- Metadata,
- Minimum prices of the NFT collection.
Coin Gecko API offers a free plan! As well as several paid plans with additional features and support.
Binance:
Binance is considered one of the largest cryptocurrency exchange platforms globally. It allows users to buy and sell digital assets.
Its free API allows web developers to interact with the Binance platform and create custom trading applications such as:
- Perform transactions and check your account balances.
- View your trading history via the API.
- It allows developers to create custom trading strategies and automate their trading activities.
The world of cryptocurrency is constantly changing, evolving, and expanding. APIs make it easy for web developers to create cryptocurrency-related apps, wallets, exchanges, and analytics tools. This makes it much easier for traders to monitor trends within the cryptocurrency market.

US Cryptocurrency Rules Delayed by ‘Never-Ending’ Lawsuits

Ripple CEO says cryptocurrency industry still seeking regulatory clarity from US
Speaking to Bloomberg News on Wednesday (July 17), Author: Brad Garlinghouse he said America is behind behind other countries which have already adopted cryptocurrency regulations.
“What we’re seeing, where it’s the UK, Japan, Singapore… even the European Union, more than two dozen countries have come together to provide a framework for cryptocurrency regulation,” Garlinghouse said.
“It’s frustrating that we as a country can’t get that regulatory framework in place. And instead, we have this never-ending lawsuit coming from the SEC that doesn’t really address the problem.”
Ripple has been the target of some of these legal disputes. Securities and Exchange Commission (SEC) sued the company in 2020, accusing it of conducting a $1.3 billion operation offering of unregistered securities tied to its XRP token.
However, last year a judge ruled that only Ripple’s institutional sales of XRP, not retail sales, violated the law, a decision widely seen as a victory for the cryptocurrency industry.
As PYMNTS noted at the time, that ruling has “far-reaching repercussions impact across the digital asset ecosystem, which has long maintained that its tokens do not represent securities contracts.”
However, Garlinghouse told Bloomberg on Wednesday that the company cannot wage multimillion-dollar legal battles over each token.
He spoke to the news agency from the Republican National Convention in Milwaukee, where the party is backing the candidacies of former President Donald Trump and Ohio Sen. J.D. Vance, both of whom are considered pro-cryptocurrency.
But Garlinghouse argued that cryptocurrencies “should not be a partisan issue,” and noted that he had recently attended a conference in Washington that included Democrats, including White House officials.
“I think they were there, listening to the industry… it was refreshing to start having that conversation,” she said.
President Joe Biden earlier this year he vetoed a measure which would have ended the SEC’s special rules for crypto-asset custodians. This legislation was supported by both the digital asset industry and the banking industry.
Ripple early this year donated $25 million to the cryptocurrency industry’s super PAC Fair Smoothiewith Garlinghouse stating at the time that such donations would continue every year, as long as the industry had its detractors.
Second Open SecretsWhich monitor spending For campaigns, the PAC has spent $13.4 million this year, much of it to help defeat Rep. Katie Porter’s (D-Calif.) U.S. Senate campaign.

The decentralized nature of cryptocurrencies offers many benefits, but it also presents unique security challenges. Cyber risks such as hacking, phishing, and ransomware pose threats to the integrity of digital assets. The infrastructure that supports cryptocurrencies is not immune to vulnerabilities, including smart contract flaws and exchange hacks.
To address these vulnerabilities, the infrastructure that supports cryptocurrencies must be strengthened. Smart contract vulnerabilities, exchange hacks, wallet breaches, and flaws in the underlying blockchain technology are significant concerns that must be addressed to ensure the security and integrity of digital assets.
As cybercriminal tactics and techniques become more sophisticated, the cryptocurrency industry must stay ahead of the curve. The future will likely see more targeted attacks, exploiting weaknesses in infrastructure, networks, and human factors. This requires a proactive and multifaceted approach to cybersecurity.
To mitigate these risks, several measures must be adopted:
Strengthening security measures: Developers, exchanges, and wallet providers must improve security protocols, use strong encryption, implement multi-factor authentication, and conduct regular security audits.
Education and awareness: Users should be educated on best practices for protecting their digital assets, including using strong passwords, recognizing phishing attempts, and using hardware wallets for secure storage.
Looking ahead, the cryptocurrency industry is expected to see an increased focus on robust security measures. Blockchain projects and exchanges are likely to invest in advanced encryption techniques and decentralized storage solutions to protect user assets. The future impact of cyber risk on cryptocurrencies will depend on the collective efforts of stakeholders to address vulnerabilities and strengthen security measures.
Collective efforts by stakeholders in the cryptocurrency space are crucial to address vulnerabilities and strengthen security measures. While challenges persist, advances in cybersecurity technologies and practices offer hope for a more secure and resilient cryptocurrency ecosystem.
The future of cybersecurity in the cryptocurrency industry depends on finding a balance between innovation and regulation. It requires a collaborative effort from all parties involved, from developers to end users, to create a secure environment that fosters trust and growth in the industry. As we move forward, it is critical that lessons learned from past events guide the development of stronger security measures, ensuring the longevity and stability of cryptocurrencies as a vital part of the modern economic toolkit.

Bullish XRP and RLBK price predictions rise, outpacing the broader cryptocurrency market, prompting Shiba Inu holders to switch!

Bitcoin’s one-week surge from $60,000 has pushed other cryptocurrencies into an uptrend. However, for many altcoins, this trend has been temporary. Altcoins such as XRP and Shiba Inu (SHIB) have experienced price drops. However, Rollblock, a new altcoin on the Ethereum blockchain, has thrived during this period, attracting thousands of investors looking for long-term growth.
XRP’s Nearly 30% Growth Over Last Week Drops as Selling Pressure Increases
XRP is seeing further price decline as Ripple investors withdraw their profits from the token. The surge in XRP’s price to $0.64 in the past week has provided investors with a perfect opportunity to increase their returns in the short term. With the ongoing sell-off in XRP, XRP has jumped over 8% in the past day and is now trading at $0.59. However, analysts tracking XRP indicators predict that XRP could still extend its gains by over 30% in the coming weeks.
Shiba Inu (SHIB) marks its third consecutive day of losses
Shiba Inu (SHIB) is in a period of adjustment after a week of strong gains. In the last 24 hours, SHIB has seen a jump of over 7%, reflecting a natural market fluctuation. Analysts are observing a death cross on the Shiba Inu chart, which historically signals the potential for future opportunities as the market stabilizes. As investors explore new possibilities, some are diversifying into promising altcoins like Rollblock (RBLK) to strategically rebalance their portfolios and capitalize on the emerging trend.
Rollblock (RBLK) Up Another 7% as New Investors Join Pre-Sale
Rollblock (RBLK) has taken the cryptocurrency market by storm, having attracted investors from more popular altcoins like Shiba Inu (SHIB) and XRP. Rollblock’s growth is attributed to its utility in the $450 billion global gaming industry.
Rollblock aims to use blockchain technology to bridge the gap between centralized and decentralized gambling. With blockchain technology, Rollblock secures every transaction in its online casino, providing transparency and convenience to millions of players who are uncomfortable placing bets on other iGaming platforms.
This innovative use of blockchain technology in the industry has grown Rollblock to over 4,000 new users in less than two months. With plans to add sports betting, this number is expected to grow exponentially in Q3.
Rollblock uses a revenue sharing model that splits up to 30% of its casino’s weekly profits with token holders. This happens after Rollblock buys back $RBLK from the open market and uses half of it for rewards. The other half is burned to increase the price of $RBLK.
Rollblock price has seen four increases in the past month with $RBLK tokens now selling for $0.017. Analysts predict that at the current growth rate, Rollblock could increase by over 800% before the presale ends. For investors looking for a long-term token with growth potential, phase four is the best time to buy Rollblock before its price skyrockets!

Texas Crypto Miners Turn to AI as Crypto Declines

As cryptocurrency mining becomes less profitable, Texas cryptocurrency mining companies are switching to supporting artificial intelligence companies.
Bitcoin miners, with their sprawling data centers and access to significant energy resources, are ideally suited for computationally intensive AI operations, and as cryptocurrency mining becomes less profitable, companies see this shift as a logical answer to their problems.
On Thursday, Houston-based Lancium and Denver-based Crusoe Energy Systems announced a multibillion-dollar deal to build a 200-megawatt data center near the West Texas city of Abilene to support advanced artificial intelligence applications such as medical research and aircraft design, CNBC reported. The plant represents the first phase of a larger 1.2 gigawatt project.
Lancium and Crusoe’s move into AI mirrors a broader trend among bitcoin miners. The combined market capitalization of the top U.S.-listed bitcoin miners hit a record $22.8 billion in June. Companies like Bit Digital and Hut 8 are diversifying into AI, with Bit Digital securing a $92 million annual revenue deal to supply Nvidia GPUs and Hut 8 raising $150 million to expand its AI data center.
But the growing popularity of these operations also presents challenges, particularly for the Texas power grid. Last month, the Electric Reliability Council of Texas announced that the state is expected to nearly double its energy production by 2030 to meet the high energy demands of data centers and cryptocurrency operations.
Lieutenant Governor Dan Patrick expressed concern about the projections.
“Cryptocurrency miners and data centers will account for more than 50% of the additional growth. We need to take a close look at these two sectors,” He wrote on Twitter/X. “They produce very few jobs compared to the incredible demands they place on our network. Cryptocurrency miners could actually make more money selling electricity to the network than they do from their cryptocurrency mining operations.”
Analysts predict significant growth in data center power capacity, which is expected to account for up to 9% of U.S. electricity consumption by 2030.
The operations also pose challenges for nearby cities. Earlier this month, TIME reported that a crypto-mining facility was seriously compromising the health of residents in the city of Granbury. TIME reported more than 40 people with serious health problems, including cardiovascular disease, high blood pressure and hearing loss. At least 10 of the residents needed to go to the emergency room or an urgent care facility.
The disturbances were caused by the extreme noise generated by the crypto-mining facility’s fans, which are used to keep the machines cool. While the proposed data center in Abilene would use liquid cooling systems, it’s still unclear whether the facility’s operations would pose a health risk to local residents.
