How to Choose the Best Crypto API for Your Project

With so many options, careful API evaluation is crucial. Consider the following practical factors before integrating a new crypto API:

  • Data Accuracy & Latency: Reliable feeds are essential for trading, especially in volatile markets. Test latency and double-check for data aggregation delays.
  • Coverage & Network Support: Confirm the API supports the blockchains, trading pairs, and tokens relevant to your use case. Some APIs focus on BTC/ETH, while others support long-tail assets and new chains.
  • Security & Compliance: Ensure the API provider follows best practices (rate limits, authentication, encryption). If handling user data or funds, review their compliance documentation.
  • Cost & Scalability: Assess free tiers, paid plans, and limits on requests per second. Advanced projects may require enterprise pricing for higher throughput.
  • Developer Experience: Look for well-documented endpoints, active community support, and SDKs in your preferred language.
  • AI & Analytics Features: APIs that include ML-driven analytics, sentiment scoring, backtesting data, or alerts can provide a competitive edge for automated trading or portfolio management.

Test multiple APIs in sandbox environments to validate uptime, accuracy, and compatibility with your backend infrastructure or front-end frameworks.

API Use Cases: Trading Automation, Price Intelligence & Wallet Integration

Strategic API integration expands what’s possible for developers and crypto businesses. Consider three core implementation scenarios for 2025:

  • Automated Trading Strategies: Connect trading APIs (e.g., Binance, Kraken) and analytics engines (Token Metrics, CryptoCompare) as your bot’s data and execution layer. Tight, low-latency connections are vital where milliseconds can matter.
  • Real-Time Price Alerts & Analytics: Combine a crypto price API with machine learning or user-defined triggers to drive actionable notifications, portfolio rebalances, or smart dashboards. Integrate advanced analytics from providers like Token Metrics or Moralis for deeper insights.
  • Wallet & Web3 dApp Functionality: Utilize APIs like Alchemy, Fireblocks, or Moralis for creating user-friendly wallets, NFT apps, or secure on-chain account management. These offer seamless blockchain interactions and abstract away complex infrastructure challenges.

For teams scaling across blockchains or global jurisdictions, modular design using the leading crypto APIs ensures adaptability and resilience as the ecosystem evolves in 2025 and beyond.

The crypto API landscape is moving fast with several trends shaping developer choices and user expectations:

  • Open Source & Community-Led APIs: More projects are releasing open APIs, encouraging collaboration and faster problem-solving for security or integration issues.
  • AI-Powered Data & Risk Tools: APIs offering on-chain analytics, anomaly detection, or AI price prediction are gaining traction for smarter trading and compliance.
  • Cross-Chain Compatibility: Universal wallet APIs and bridges make it easier to support multi-chain assets and DeFi protocols in one place.
  • Improved Privacy & Decentralization: Zero-knowledge proofs and secure computation features are increasingly offered at the API level for confidential transactions.
  • Regulatory Readiness: Providers are adopting stricter KYC/AML processes, especially for trading and custodian APIs, to meet global compliance demands.

Whether you’re prototyping a new app or enhancing a mature platform, staying up-to-date with these innovations ensures your tech stack remains competitive and agile as the regulatory and market landscape shifts.

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. That’s why the integration of the Token Metrics Crypto Data API with Dune is a game-changer for anyone seeking to create live dashboards backed by intelligent trading data.

In this post, we’ll walk through how to use this top crypto API to build dynamic dashboards on Dune. Whether you’re tracking bullish signals, backtesting trading strategies, or identifying top-performing tokens, this integration makes it possible—without any paid license.

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

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.

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

Token Metrics Team
8 min
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.

What Is an ETF in Crypto? A Complete Guide for Crypto Investors in 2025

Token Metrics Team
8 min
MIN

The world of crypto investing is expanding at lightning speed. With growing institutional adoption and mainstream interest, new financial instruments are emerging to make crypto more accessible to everyday investors. One of the most impactful of these tools is the Exchange-Traded Fund (ETF) — and in 2025, crypto ETFs are playing a crucial role in shaping the future of digital asset investing.

📊 What Is an ETF?

An ETF (Exchange-Traded Fund) is a type of investment fund traded on traditional stock exchanges, just like individual stocks. ETFs hold a basket of assets such as stocks, bonds, commodities—or, in this case, cryptocurrencies.

When you buy shares of an ETF, you’re investing in a diversified portfolio managed by an institution. Instead of buying each asset individually, ETFs let you gain exposure to a group of assets through a single security.

đŸȘ™ What Is a Crypto ETF?

A crypto ETF is a special type of ETF that tracks the price of one or more cryptocurrencies, such as Bitcoin, Ethereum, or a basket of altcoins. These ETFs allow investors to gain exposure to crypto markets without needing to buy, store, or manage digital assets directly.

Crypto ETFs are listed on traditional financial exchanges (like Nasdaq or NYSE) and can be purchased via brokerage accounts—making them ideal for both institutional investors and crypto-curious retail traders.

🔍 Types of Crypto ETFs

There are two main categories of crypto ETFs:

1. Spot Crypto ETFs

  • Directly hold the underlying cryptocurrency (e.g., Bitcoin, Ethereum).
  • Track the real-time price of the asset.
  • Considered the most accurate and direct method of gaining crypto exposure.
  • Example: BlackRock’s iShares Bitcoin Trust.

2. Futures-Based Crypto ETFs

  • Do not hold actual cryptocurrency.
  • Invest in futures contracts that speculate on the asset’s future price.
  • Prone to “tracking errors” and additional management fees.
  • Example: ProShares Bitcoin Strategy ETF (BITO).

In 2025, spot ETFs have become more popular, especially after multiple approvals in major markets like the U.S., Canada, and Hong Kong.

✅ Benefits of Crypto ETFs

Crypto ETFs offer a range of advantages for investors seeking exposure to digital assets without managing crypto wallets or private keys.

1. Accessibility

  • Trade crypto exposure from a traditional brokerage account.
  • No need for crypto exchanges, wallets, or DeFi protocols.

2. Regulation and Security

  • Managed by licensed institutions and regulated by bodies like the SEC.
  • Custody solutions are handled by professionals (e.g., Coinbase Custody, Fidelity Digital).

3. Diversification

  • Some ETFs offer exposure to a basket of cryptocurrencies, reducing risk.
  • Others may focus on specific sectors like DeFi or metaverse tokens.

4. Tax and Retirement Account Eligibility

  • Can be included in IRAs, 401(k)s, and tax-advantaged portfolios in some jurisdictions.

⚠ Risks of Crypto ETFs

While crypto ETFs simplify access, they are not risk-free.

1. Management Fees

  • ETFs charge annual fees (0.20%–1.00%), which can affect long-term gains.

2. Lack of Full Ownership

  • You don’t hold the actual coins, so you can’t use them for staking, yield farming, or DeFi.

3. Volatility

  • Crypto markets are still highly volatile. ETF prices can fluctuate rapidly.

4. Tracking Errors (Futures ETFs)

  • Futures-based ETFs often lag behind the spot price of the cryptocurrency.

💡 Why Crypto ETFs Matter in 2025

The launch and adoption of crypto ETFs signal mainstream validation of the crypto market.

  • Over $60 billion has poured into Bitcoin and Ethereum ETFs since early 2024.
  • Institutional players like BlackRock, Fidelity, and ARK Invest are leading issuers.
  • Spot Bitcoin ETFs helped propel BTC above $118,000 in July 2025.
  • Regulatory green lights from the SEC, MAS, and other regulators mark a shift in global crypto policy.

Crypto ETFs reduce barriers to entry and give traditional investors a safe, regulated way to participate in the digital economy.
