Whether you’re a crypto enthusiast building a portfolio tracker, a data scientist enhancing your research with blockchain statistics, or a developer powering an AI agent with on-chain data, the right API can unlock game-changing insights without hefty costs. As access to transparent crypto data becomes increasingly important, many turn to free APIs to gather reliable stats on digital assets—yet navigating the options can be daunting. In this guide, we break down some of the best free APIs for crypto statistics, what to consider when choosing one, and how developers leverage these tools for research, analytics, and building smarter applications.

Understanding Crypto APIs and Why They Matter

A crypto API (Application Programming Interface) serves as a bridge between live blockchain data and your application or research workflow. These interfaces allow you to fetch real-time prices, historical charts, market capitalization, trading volumes, on-chain metrics, and sometimes deep project statistics. Unlike manual data collection, APIs automate the process, saving vast amounts of time and reducing human error. As web and AI applications increasingly rely on real-time digital asset data, choosing trustworthy and feature-rich APIs is critical for accuracy and efficiency.

  • Real-time stats: APIs enable on-demand access to fast-moving market data across hundreds or thousands of tokens, exchanges, and blockchains.
  • Historical analytics: Developers and analysts can retrieve time-series data for backtesting or portfolio analysis.
  • On-chain insights: Some APIs focus on network activity, token holders, or smart contract interactions—critical for blockchain research and AI models.

Best Free Crypto APIs for Stats: Comparing Top Choices

Not all free APIs are equal. Here are some reputable platforms that provide complimentary tiers for accessing crypto stats, with a brief overview of their strengths:

  1. CoinGecko API: Widely used for its open and generous free tier, CoinGecko offers real-time prices, historical data, market cap, volume, and metadata for thousands of coins. Its robust documentation and community support make integration straightforward for beginners and pros.
  2. CoinMarketCap API: Backed by a vast database, CoinMarketCap delivers real-time and historical market data for tracked assets, with basic statistics available on its free plan. Request limits are lower than some competitors, but it’s useful for basic queries.
  3. CryptoCompare API: Provides aggregated price feeds, exchange data, coin ratings, and social sentiment—great for broad coverage. Its free plan comes with limited calls and fewer custom features versus paid tiers.
  4. Blockchain.com Data API: Focused on Bitcoin network metrics (hash rate, block details, raw transactions), this API is perfect for on-chain analytics, albeit limited to BTC.
  5. Token Metrics API: For developers wanting to go beyond standard stats, the Token Metrics API offers a free tier for real-time prices, trading signals, AI-powered analytics, and on-chain data in a single endpoint. It’s designed for advanced research and integration with AI agents.
  6. Messari API: Delivers in-depth fundamental data, project profiles, and select statistics via its free tier. Messari’s API is a favorite for those seeking fundamental, non-price metrics.
  7. Glassnode API (Community Tier): Excellent for network analytics and on-chain visualization—limited to select metrics but highly useful for technical research.

Each API varies in terms of available endpoints, usage limits, latency, and scope. For many projects, especially AI-driven tools and bots, evaluating these criteria is just as important as price.

Key Criteria: How to Evaluate a Free Crypto Statistics API

Before selecting an API, developers and data analysts should apply a systematic framework to ensure the tool matches their use case. Consider:

  • Data coverage: Does the API offer all needed endpoints—prices, volumes, on-chain stats, project metadata?
  • Reliability: Look for uptime records, user reviews, and community trust. Frequent outages or unmaintained APIs might undermine your project.
  • Rate limits: Free plans often cap daily or minute-by-minute requests. Ensure these align with your data frequency needs (e.g., real-time vs. periodic updates).
  • Data freshness: Latency matters. Markets move fast, so choose APIs that minimize lag in delivering updates.
  • Documentation and support: Good docs speed integration and reduce errors. Community forums or Discord support are big pluses for troubleshooting.
  • Special features: Some APIs offer unique endpoints for social sentiment, AI signals, on-chain analytics, or cross-chain support.

Researching these factors upfront will help avoid integration headaches later.

Practical Ways to Use Free Crypto Stat APIs

Free APIs empower a variety of users beyond developers—from quant researchers to hobbyists, and even AI tool builders. Some common applications include:

  • Portfolio analytics tools: Fetch live balances and historical prices for asset management dashboards.
  • Market research bots: Build automated scrapers or AI agents that track trending assets and network activity.
  • Academic research: Gather historical, social, and on-chain datasets for blockchain or financial research papers.
  • On-chain anomaly detection: Monitor large transactions and changes in network metrics to surface suspicious or significant activity.
  • Trading signal development: Test quantitative strategies using historical stat APIs—always in a research context (avoid investment advice).

Free APIs are especially valuable for prototyping or academic work, allowing experimentation without financial barriers.

Limitations and Considerations for Free Crypto APIs

While many free APIs are robust, it’s vital to recognize their limits:

  • Restricted features: Advanced endpoints (like deep on-chain analytics or AI predictions) may require paid access or have throttled response times on free plans.
  • Rate restrictions: Heavy use—such as running a live trading bot—may exceed free limits, resulting in failed requests or delayed data.
  • Data accuracy: Verify data sources, as inconsistencies can occur in community-maintained APIs.
  • Longevity and support: Free APIs may change terms or sunset endpoints with little warning; it’s smart to plan for redundancy or migrate to paid tiers if scaling a critical project.

Always monitor usage and test with sample queries before deeply embedding an API into your application stack.

What Is an NFT? Complete Guide to Non-Fungible Tokens (2025)

Token Metrics Team
6 min
MIN

Over the past few years, NFTs (Non-Fungible Tokens) have exploded in popularity—revolutionizing the way we think about digital ownership, art, gaming, collectibles, and more. In 2025, NFTs continue to shape the future of the internet, transforming everything from music rights to virtual real estate.

If you're wondering “What is an NFT?” or how they actually work, this guide breaks it down for you. We’ll also explore how AI-powered tools like Token Metrics can help you identify high-value NFT-related tokens and investment opportunities.

🔍 What Does NFT Stand For?

NFT stands for Non-Fungible Token. Let’s break that down:

  • Token: A digital asset that exists on a blockchain.
  • Non-Fungible: It’s unique and cannot be replaced with something else of equal value. (Unlike cryptocurrencies like Bitcoin, where each BTC is the same.)

So, an NFT is a unique digital asset stored on a blockchain, representing ownership of a specific item—like artwork, music, a tweet, a game character, or a piece of virtual land.

🎹 What Can Be an NFT?

NFTs aren’t just limited to pixelated apes or JPEGs. In 2025, NFTs power a broad range of digital assets:

  • Digital Art: Artworks, animations, and generative art
  • Collectibles: Rare items like trading cards or profile picture (PFP) projects
  • Gaming Assets: In-game skins, weapons, characters, and land (e.g., in The Sandbox or Decentraland)
  • Music and Media: Songs, albums, and exclusive content drops
  • Virtual Real Estate: Land parcels in the metaverse
  • Domain Names: Blockchain-based domain ownership
  • Identity & Access: Membership passes, event tickets, or certification credentials

Each NFT has a unique identifier and metadata that distinguish it from any other asset.

đŸ› ïž How Do NFTs Work?

NFTs are built and recorded on blockchains, most commonly on Ethereum using ERC-721 or ERC-1155 standards. Here’s how they work:

  1. Minting: Turning a digital file into a token on the blockchain
  2. Metadata: Storing details like title, creator, image URL, and traits
  3. Ownership: A smart contract verifies the wallet that owns the NFT
  4. Transferability: NFTs can be sold, traded, or gifted using marketplaces

Because of blockchain immutability, ownership is transparent, verifiable, and permanent.

📈 Why Are NFTs Valuable?

Several reasons explain the rising value and popularity of NFTs:

  • Digital Ownership: You own the asset—not a platform
  • Proven Scarcity: Many NFTs are limited in supply
  • Creator Royalties: Artists earn fees on secondary sales
  • Utility & Access: Some NFTs unlock real-world benefits, games, or private groups
  • Social Status: PFPs like CryptoPunks or Bored Ape Yacht Club are digital status symbols
  • Speculation: Many treat NFTs as investments, betting on future appreciation

In 2025, NFTs have gone beyond hype to form the foundation of Web3 identity and ownership.

💰 How to Buy an NFT

To buy an NFT, you’ll need:

  1. A crypto wallet (like MetaMask)
  2. Some ETH or other supported crypto for payment and gas fees
  3. An NFT marketplace like OpenSea, Blur, Magic Eden, or Rarible

Steps to Buy:

  • Fund your wallet
  • Connect to a marketplace
  • Browse collections
  • Click “Buy Now” or place a bid
  • Approve the transaction

Once purchased, the NFT is transferred to your wallet and viewable on your profile.

⚠ Are NFTs Safe?

NFTs are secure if you follow best practices. However, scams and phishing attacks are common.

Security Tips:

  • Never share your seed phrase
  • Verify contract addresses before minting
  • Don’t connect your wallet to unknown sites
  • Use hardware wallets for high-value NFTs
  • Bookmark official sites

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

Token Metrics Team
6 min
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)

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.
