In today's digital asset ecosystem, Application Programming Interfaces, or APIs, are the unsung heroes enabling everything from cryptocurrency wallets to trading bots. Whether you're a developer building for Web3 or a curious user interested in how your exchange functions, understanding how crypto APIs work is essential

    What Is a Crypto API?

    A crypto API is a set of programming instructions and standards that allow software applications to communicate with cryptocurrency services. These services may include wallet functions, price feeds, trading engines, exchange platforms, and blockchain networks. By using a crypto API, developers can automate access to real-time market data or execute trades on behalf of users without manually interacting with each platform.

    For instance, the Token Metrics API provides structured access to cryptocurrency ratings, analytics, and other data to help teams build intelligent applications.

    Types of Crypto APIs

    There are several categories of APIs in the cryptocurrency landscape, each with different capabilities and use cases:


       

       

       

       

       


    How Crypto APIs Work

    At their core, crypto APIs operate over internet protocols—typically HTTPS—and return data in JSON or XML formats. When an application makes a request to an API endpoint (a specific URL), the server processes the request, fetches the corresponding data or action, and sends a response back.

    For example, a crypto wallet app might call an API endpoint like /v1/account/balance to check a user’s holdings. To ensure security and authorization, many APIs require API keys or OAuth tokens for access. Rate limits are also enforced to prevent server overload.

    Behind the scenes, these APIs interface with various backend systems—blockchains, trading engines, or databases—to fulfill each request in real time or near real time.

    Common Use Cases for Crypto APIs

    Crypto APIs are used across a broad spectrum of applications:

    APIs dramatically reduce time-to-market for developers while enhancing user experience and application efficiency.

    Key Considerations for API Integration

    When integrating a crypto API, consider the following factors:


       

       

       

       

       


    Platforms like the Token Metrics API provide both comprehensive documentation and reliability for developers building AI-powered solutions in crypto.

    AI-Powered Analytics and APIs

    Some of the most powerful crypto APIs now incorporate artificial intelligence and machine learning features. For example, the Token Metrics API facilitates access to predictive models, coin grades, and AI-based price forecasts.

    By embedding these tools into custom apps, users can programmatically tap into advanced analytics, helping refine research workflows and support technical or fundamental analysis. Although these outputs can guide decisions, they should be viewed in a broader context instead of relying exclusively on model predictions.

    Conclusion

    Crypto APIs are critical infrastructure for the entire digital asset industry. From data retrieval and trading automation to blockchain integration and AI-driven analytics, these tools offer immense utility for developers, analysts, and businesses alike. Platforms such as Token Metrics provide not only in-depth crypto research but also API access to empower intelligent applications built on real-time market insights. By understanding how crypto APIs work, users and developers can better navigate the rapidly evolving Web3 landscape.

    How to Store Cryptocurrency Safely in 2025 | Hot vs Cold Wallets

    Token Metrics Team
    6 min

    Cryptocurrency offers unmatched freedom, but with that freedom comes responsibility—especially when it comes to how to store cryptocurrency securely. Unlike traditional banking, crypto is self-custodied. If you lose access to your wallet, your funds are gone forever.

    This guide explains everything you need to know about storing crypto in 2025, including:

    • Why crypto storage matters
    • Types of crypto wallets
    • Hot wallets vs. cold wallets
    • Tips for securing your assets
    • How platforms like Token Metrics can help protect your investment

    đŸȘ™ Why Is Storing Cryptocurrency Important?

    When you buy crypto—whether it’s Bitcoin, Ethereum, or a promising moonshot altcoin—you receive private keys that give you access to your funds. Anyone with that key can spend your coins.

    That’s why safe storage is critical. Without it, your assets are vulnerable to:

    • Hacks and phishing scams
    • Lost devices or forgotten passwords
    • Exchange collapses or rug pulls

    You are your own bank, and your security strategy is your vault.

    🔐 What Is a Crypto Wallet?

    A crypto wallet is a digital tool that stores your private and public keys. It lets you send, receive, and manage your crypto.

    There are two main types:

    1. Hot wallets – connected to the internet
    2. Cold wallets – offline and physically secured

    Let’s explore both.

    🌐 Hot Wallets: Convenience Meets Risk

    Hot wallets are always online, making them easy to use for trading, DeFi, or daily transactions.

    Types of Hot Wallets:

    • Web wallets (e.g., MetaMask, Trust Wallet)
    • Mobile apps (e.g., Coinbase Wallet, Phantom)
    • Desktop wallets (e.g., Exodus, Electrum)

    Pros:

    • Quick access to funds
    • Easy integration with DApps and exchanges
    • Great for beginners and active traders

    Cons:

    • Higher risk of hacks, malware, and phishing
    • Device or browser compromise can expose keys

    Best Practices for Hot Wallets:

    • Use 2FA (Two-Factor Authentication)
    • Never store large amounts
    • Double-check URLs to avoid fake websites
    • Avoid public Wi-Fi while transacting

    🧊 Cold Wallets: Ultimate Security

    Cold wallets are offline storage solutions, ideal for long-term investors or large holdings.

    Types of Cold Wallets:

    • Hardware wallets (e.g., Ledger Nano X, Trezor)
    • Paper wallets (QR code + private key printed on paper)
    • Air-gapped devices (old smartphones with no internet access)

    Pros:

    • Immune to online hacks
    • Best for HODLing and large sums
    • You own full control

    Cons:

    • Less convenient for daily use
    • Loss or damage without backups = permanent loss

    Best Practices for Cold Wallets:

    • Buy hardware wallets directly from the manufacturer
    • Backup your seed phrase on metal plates or offline storage
    • Keep backups in secure, separate locations

    🔄 Custodial vs. Non-Custodial Wallets

    🏩 Custodial Wallets

    Managed by exchanges (e.g., Binance, Coinbase). You don’t own the private keys.

    Pros:

    • Easy to use
    • Ideal for beginners

    Cons:

    • Not your keys, not your crypto
    • Vulnerable to hacks or platform failures

    🔓 Non-Custodial Wallets

    You own the keys. Wallets like MetaMask, Trust Wallet, or hardware devices.

    Pros:

    • Full control and ownership
    • Safer long-term storage

    Cons:

    • Losing your seed phrase = permanent loss
    • Requires more responsibility

    Tip: Token Metrics recommends non-custodial wallets for storing long-term holdings and moonshot tokens.

    🔐 How Token Metrics Enhances Crypto Security

    Token Metrics is an AI-powered crypto research and trading platform trusted by thousands of investors. While it doesn’t store your crypto directly, it helps you manage risk and store assets wisely by:

    1. Identifying Safe Assets

    Token Metrics gives you AI-generated grades for tokens—helping you avoid scams and invest in credible projects worth storing long-term.

    2. Trading Tools with Wallet Integration

    You can explore tokens, assess moonshots, and initiate trades directly from your connected Web3 wallet without leaving the platform.

    3. Portfolio Tracking with Security

    Token Metrics allows you to track wallets and portfolio performance without requiring access to your private keys.

    4. Educational Guidance

    Through webinars, blog content, and investor resources, Token Metrics educates users on how to safely store their crypto in hot and cold wallets.

    🧠 Tips to Keep Your Crypto Safe in 2025

    ✅ Use Hardware Wallets for Large Amounts

    Your long-term Bitcoin, Ethereum, and moonshot tokens should live on a hardware wallet, not on an exchange.

    ✅ Store Your Seed Phrase Offline

    Do NOT keep your recovery phrase in Google Docs or your phone. Use metal seed phrase storage or write it down and lock it in a safe.

    ✅ Use Multiple Wallets

    Diversify storage:

    • Hot wallet for daily use
    • Cold wallet for savings
    • Separate wallet for DeFi

    ✅ Avoid Suspicious Links and Apps

    Phishing is the #1 crypto threat. Double-check URLs, don’t sign unknown transactions, and avoid shady browser extensions.

    ✅ Monitor Wallet Activity

    Use platforms like Token Metrics Alerts or Etherscan to track your wallet and get notified of suspicious activity.

    đŸȘ™ How to Store Different Types of Crypto

    ‍

    🧭 Final Thoughts

    Storing cryptocurrency securely is just as important as choosing the right tokens to invest in. Whether you’re a day trader, long-term investor, or moonshot hunter, knowing when and where to store your crypto is key to protecting your wealth.

    In 2025, the best strategy combines:

    • Cold wallets for large, long-term holdings
    • Hot wallets for convenience and trading
    • Non-custodial options to retain full control
    • AI tools like Token Metrics to identify trustworthy assets and avoid scams

    When you store your crypto properly, you don’t just protect your assets—you gain peace of mind.

    Token Metrics Team
    8 min

    In today’s fast-paced crypto world, real-time data isn’t a luxury—it’s a necessity. For traders, analysts, and developers, being able to access live, actionable insights can mean the difference between profit and loss.

    Let’s dive into how you can use the best free crypto API available today to transform your trading.

    What Is the Token Metrics Crypto Data API?

    The Token Metrics Crypto Data API is a developer-focused gateway to powerful, AI-driven crypto data. It’s one of the top crypto APIs in 2025, giving you access to:

    • Real-time and historical trading signals
    • Proprietary trader and investor grades
    • Alpha metrics comparing trading vs. holding performance
    • Bullish and bearish token flags

    This API is used by both professional quant traders and beginners seeking to automate insights. And the best part? Token Metrics provides free crypto API access to selected datasets, allowing you to create powerful dashboards without spending a dime.

    Why Dune + Token Metrics API = Power Tools for Traders

    Dune is a blockchain analytics platform that allows you to write SQL queries and create dashboards using on-chain and off-chain data. Now that Token Metrics datasets are available on Dune, you can combine the best of both worlds:

    • Free access to high-signal proprietary metrics
    • Real-time data visualizations via Dune’s drag-and-drop dashboard builder
    • Actionable insights based on AI-driven trading intelligence

    This integration unlocks a whole new level of transparency and utility for crypto analysts, portfolio managers, and DeFi enthusiasts.

    Getting Started: Accessing Token Metrics Data on Dune

    To begin, create a free Dune account. Once logged in, navigate to the Token Metrics datasets. These are publicly accessible and updated regularly. You’ll find tables for:

    • trading_signals
    • trader_grades
    • investors_grades
    • tokens

    Start a new SQL query and choose the dataset you want to explore. Here’s what you’ll find in the trading signals table:

    ‍

    ‍

    Step-by-Step: Creating an Actionable Dashboard with Token Metrics Data

    1. Query the Trading Signal Returns

    Write a SQL query to calculate the average return of trading vs. holding strategies. For example:

    This gives you the alpha—how much better the Token Metrics strategy performs compared to just HODLing.

    In one real example, the average signal return across all tokens was 1630%, while holding returned just 400%. That’s a 12X improvement powered by this top crypto API.

    2. Identify Top-Performing Tokens

    Now let’s list tokens with the highest average alpha:

    Tokens like BTC, ETH, BNB, and even newer ones like Virtuals stand out due to exceptional alpha performance.

    3. Visualize Trader Grades vs. Alpha

    The trader grade is a proprietary score from Token Metrics that predicts how favorable a token is for short-term traders.

    Use a scatter plot to correlate trader grades with average alpha:

    • X-axis: Trader Grade
    • Y-axis: Average Alpha
    • Group by: Token Symbol

    This helps you visually determine which tokens score high and offer exceptional returns—an essential tool for making actionable trading decisions.

    4. Track the Latest Bullish Signals

    Want to know which tokens are bullish right now? Here’s a query to find the most recent tokens flagged as bullish:

    For example, on July 4th, tokens like BNB, XRP, and BTC were among the most recent bullish signals—perfect for immediate trade setups.

    5. Build and Share Your Dashboard

    Once you’ve run your queries:

    • Click “Add Visualization” in Dune
    • Choose from chart types (bar, scatter, progress bar, etc.)
    • Customize colors and filters
    • Combine multiple charts into a single dashboard

    Your final product will be a real-time dashboard powered by the best crypto API, delivering insights that you—and your team—can act on instantly.

    ✅ Proprietary Metrics

    Access unique indicators like trader grade and investor grade, unavailable anywhere else.

    ✅ Real Historical Alpha

    Use the API to backtest strategies. In the example shown, the AI strategy outperformed the market by over 1000X for some tokens.

    ✅ Seamless Integration

    Whether you're using Dune, Zapier, OpenAI, or Eliza OS, Token Metrics is easy to integrate and query—making it the top crypto API for developers and analysts alike.

    What Is an ETF Stock? A Beginner’s Guide to Exchange-Traded Funds in 2025

    Token Metrics Team
    8 min

    In today’s fast-moving financial markets, Exchange-Traded Funds, or ETF stocks, have emerged as one of the most popular investment vehicles for beginners and professionals alike. But what exactly is an ETF stock, how does it work, and why is it considered a smart way to invest?

    This guide will walk you through everything you need to know about ETF stocks in 2025—including how they work, their benefits and risks, and how AI platforms like Token Metrics are changing the way people research and trade ETFs in both traditional and crypto markets.

    📌 What Is an ETF Stock?

    An ETF stock refers to a share of an Exchange-Traded Fund—a type of investment fund that trades on stock exchanges, much like individual company stocks. Each ETF holds a basket of underlying assets such as:

    • Stocks (e.g., S&P 500 companies)
    • Bonds
    • Commodities (like gold or oil)
    • Currencies
    • Cryptocurrencies (Bitcoin, Ethereum, etc.)

    When you buy an ETF stock, you’re buying a fractional share of the entire portfolio of assets held by that ETF.

    🔍 How Does an ETF Stock Work?

    ETF stocks work like this:

    1. Creation: An asset management company (like BlackRock, Vanguard, or Fidelity) creates an ETF that tracks a specific index, sector, or asset type.
    2. Listing: The ETF is listed on a stock exchange such as the NYSE or Nasdaq.
    3. Trading: Investors can buy and sell ETF shares throughout the trading day, just like they would a stock like Apple or Tesla.
    4. Price Movement: The price of an ETF stock fluctuates during the day based on the Net Asset Value (NAV) of its holdings and supply-demand dynamics in the market.

    This model provides a liquid, transparent, and low-cost way for investors to gain diversified exposure to entire markets or sectors.

    📊 Example of an ETF Stock

    A good example is the SPDR S&P 500 ETF Trust (SPY), which tracks the performance of the S&P 500 index. When you buy a share of SPY, you gain exposure to 500 of the largest U.S. companies—without needing to buy each stock individually.

    ✅ Benefits of ETF Stocks

    ETF stocks offer numerous advantages for investors in 2025:

    1. Diversification

    Instead of buying individual assets, ETF stocks offer instant diversification by holding dozens or hundreds of securities in a single share.

    2. Liquidity

    ETFs are traded on exchanges, making them highly liquid. You can buy or sell them at market prices during normal trading hours.

    3. Lower Costs

    ETFs typically have low expense ratios (as low as 0.03%), especially compared to mutual funds or actively managed portfolios.

    4. Transparency

    Most ETFs disclose their holdings daily, giving investors a clear view into what they’re buying.

    5. Flexibility

    You can use ETFs for long-term investing, short-term trading, hedging, or generating income through dividends.

    ⚠ Risks of ETF Stocks

    Despite their many benefits, ETF stocks do come with some risks:

    1. Market Risk

    ETF stocks are still subject to market volatility. If the underlying assets decline in value, so will the ETF.

    2. Tracking Error

    Some ETFs may not perfectly replicate the performance of their index due to fees, slippage, or illiquid assets.

    3. Overexposure

    Because ETFs make it easy to invest, some investors may unknowingly become overexposed to a particular sector or strategy.

    4. Liquidity Risk

    Not all ETFs are created equal. Low-volume ETFs may have wider bid-ask spreads, increasing trading costs.

    đŸȘ™ Crypto ETFs: The New Frontier

    In 2025, crypto ETF stocks have become a hot trend. These funds allow investors to gain exposure to digital assets without managing private keys, wallets, or blockchain protocols.

    Types of crypto ETFs include:

    • Spot ETFs: Hold actual crypto assets (e.g., Bitcoin, Ethereum).
    • Futures ETFs: Track the price of crypto futures contracts.

    Popular examples in 2025 include:

    • IBIT (BlackRock Bitcoin ETF)
    • FBTC (Fidelity Bitcoin ETF)
    • ETHX (Ethereum Spot ETF)

    Crypto ETFs have opened the door for institutional and traditional investors to gain exposure to the crypto market in a regulated and simplified manner.
