That’s where the Token Metrics Crypto API comes in.

In this guide, we’ll walk you through how to integrate the Token Metrics API with Chainlink Functions, enabling you to deploy live smart contracts that interact with real-time crypto signals, token prices, and trader grades. You’ll learn how to use more than 20 API endpoints and smart contract adapters to power decentralized apps with actionable data.

If you’re searching for the best crypto API for smart contract development, or you need a free crypto API to start testing on testnets, this article is your ultimate resource.

What Is the Token Metrics Crypto API?

The Token Metrics API is an advanced data interface designed for traders, developers, and Web3 builders. It provides access to over 20 endpoints covering everything from:

  • Token prices
  • AI-powered trading signals (bullish/bearish)
  • Trader and Investor Grades (0–100 scoring system)
  • Quant metrics
  • Support and resistance levels
  • Sentiment analysis

Built by a team of quant analysts, machine learning engineers, and crypto-native researchers, the Token Metrics Crypto API brings hedge-fund-grade intelligence into the hands of everyday builders.

Why Use the Token Metrics API with Chainlink Functions?

Chainlink Functions enable smart contracts to securely retrieve off-chain data from any API. By integrating with the Token Metrics Crypto API, you can bridge institutional-grade analytics into fully decentralized apps—something not possible with basic or unreliable data sources.

Here’s why this combo is so powerful:

  • đź”— Chainlink decentralizes your execution
  • đź§  Token Metrics powers your logic with predictive analytics
  • ⚙️ Smart contracts can now act on real market intelligence

This integration enables the creation of intelligent trading bots, dynamic token allocations, and governance proposals backed by hard data—not speculation.

Step-by-Step: How to Integrate Token Metrics API with Chainlink Functions

Let’s walk through how to connect the best crypto API—Token Metrics—with Chainlink Functions to build and deploy a live smart contract.

1. Clone the GitHub Repo

Start by cloning the GitHub repository that contains the full codebase. This includes:

  • A set of ~20 pre-built smart contracts
  • API adapter logic
  • Sample scripts to interact with the contracts
  • A detailed README with setup instructions

Each smart contract is tailored to one Token Metrics API endpoint—meaning you can plug and play any dataset, from prices to sentiment scores.

2. Set Up Your Environment

The README provides a full list of recommended environment variables, including:

  • API_KEY for Token Metrics
  • LINK_TOKEN_ADDRESS
  • CHAINLINK_SUBSCRIPTION_ID
  • ORACLE_ADDRESS

Once your .env is ready, you can start compiling and deploying.

3. Build and Deploy a Sample Trading Bot Smart Contract

In this walkthrough, the developer built a Solidity smart contract that:

  • Pulls live data from Token Metrics (price, signal, grade)
  • Evaluates the signal (e.g., bullish)
  • Executes a buy trade if the signal is positive

The contract is compiled in Remix IDE, connected via MetaMask (on testnet), and deployed using testnet ETH and LINK tokens.

After deployment, you’ll receive a contract address that can be added to your Chainlink subscription.

4. Create a Chainlink Subscription

To fund your contract for data requests:

  1. Go to the Chainlink portal
  2. Create a new subscription (testnet or mainnet)
  3. Fund it with some LINK
  4. Add your deployed smart contract as a consumer

This allows your contract to make external data calls using Chainlink’s decentralized oracle network.

5. Run a Script to Invoke Real-Time Token Metrics Data

Using the provided JavaScript scripts, you can interact with the smart contract and test data flow:

  • Check the bot’s active status
  • Retrieve token price, trading signal, and grade
  • See how the smart contract responds to live market conditions

In the demo, the bot received a bullish signal, saw that the grade was high, and executed a buy trade accordingly. This logic can be expanded into full-scale trading strategies, rebalancing rules, or even on-chain governance triggers.

AI Tokens and DeFi 2.0: Where Smart Capital is Flowing

Token Metrics Team
4 min
MIN

The crypto market is cyclical—not just in price, but in narrative. In recent months, attention has rotated from AI to DeFi, creating new opportunities for savvy investors. Let’s break down the trends.

AI Momentum Remains Strong

Projects like Vader AI, BitTensor, and Grass continue to dominate the conversation. Vader AI, part of the Virtua ecosystem, gained momentum from staking programs and Genesis Launchpad allocations. Grass, a data-layer AI protocol, claims $15M+ in revenue and recently flipped bullish on technical indicators.

BitTensor remains the leading infrastructure play in the AI space, drawing parallels to Bitcoin in its community enthusiasm and decentralization ethos. It has rebounded over 150% from its lows and is showing resilience in the current market cycle.

DeFi’s Comeback: Aerodrome and Beyond

Meanwhile, DeFi is showing signs of resurgence. Aerodrome, a DEX on the Base chain, is gaining traction through strong liquidity incentives and revenue-sharing mechanisms. Its user incentives echo the early days of Curve or Uniswap but on a chain optimized for scalability.

Virtua’s staking model is also driving a hybrid DeFi/AI strategy, blurring the lines between token utility, participation, and value capture.

Narrative Rotation: What It Means

Crypto narratives are rarely zero-sum. What we’re seeing now is a healthy diversification: AI remains dominant, but DeFi is catching a second wind. For investors, this means exploring tokens that sit at the intersection—offering strong tech, compelling incentives, and infrastructure integrations.

While most exchanges compete on liquidity or UI, Hyperliquid is rewriting the rules entirely.
This decentralized perps exchange has not only survived the bear market—it’s thriving. Backed by real revenue, a growing user base, and a unique listing model, Hyperliquid is emerging as the “Uniswap of Perps.”

The Reverse Auction Listing System

Hyperliquid introduces a novel reverse auction system for listing tokens. Bidders compete for tickers, with starting prices set at 2x the previous auction. Some tickers have fetched over $1 million, with the fees used for buybacks and burns—driving long-term value to the ecosystem.

This model isn’t just a gimmick. It introduces scarcity and gamification into token listings—something no other exchange is doing at this level.

Sustainable Revenue and Strong UX

Unlike many DEXs, Hyperliquid generates consistent trading fees, even in sideways markets. Its EVM-compatible L1 is coming soon, which could further cement it as the go-to perps exchange for serious traders.

Product-Market Fit in Action

In a space where hype often outpaces adoption, Hyperliquid offers both. It's not trying to be first—it's trying to be the best. The community listing process, upcoming L1, and high trading volumes all suggest it’s built for long-term relevance.

Smarter Trading with Token Metrics

To navigate emerging platforms like Hyperliquid, sophisticated analytics are key. Token Metrics provides a powerful suite of tools—AI-driven trading signals, token grades, on-chain data, and market indicators—to help traders make confident, data-backed decisions. Whether you're evaluating new token listings, monitoring market sentiment, or comparing DEX performance, Token Metrics equips you with everything you need to stay ahead of the curve.

Final Take

Hyperliquid is more than just another DEX—it’s a case study in how to build sustainable tokenomics and community alignment. If you’re looking for the next big infrastructure play in trading, don’t sleep on this one. And if you want to trade smarter, platforms like Token Metrics can be your secret weapon in decoding the market's next moves.

Is Sui the Next Solana? A Deep Dive into L1 Competitors

Token Metrics Team
4 min
MIN

As the Layer 1 (L1) narrative continues to evolve, one blockchain has rapidly emerged as a serious contender to Solana’s throne: Sui. With growing infrastructure support and a strong focus on user experience, Sui is positioning itself as one of the most compelling L1 platforms in 2025.

Why the Sui Hype?

Sui has been gaining traction due to key integrations across the crypto ecosystem. Phantom wallet, known for its Solana roots, recently announced Sui support—putting Sui directly in the hands of thousands of users. Similarly, Axelar and LI.FI, major players in bridging and routing, have added Sui to their networks.

These integrations are not just symbolic; they’re strategic. By positioning itself as a supported chain across EVM-native infrastructure, Sui becomes more accessible and developer-friendly—critical factors for long-term adoption.

The SuiPlay Effect

Sui is also expanding beyond traditional DeFi and into consumer crypto. SuiPlay, a gaming-focused hardware device launched earlier this year, sold out in days. It marks a shift in L1 differentiation—no longer just about TPS (transactions per second), but about vertical-specific UX.

The gaming angle aligns with Sui’s broader push toward being the “consumer chain,” capturing not only dApp developers but also everyday users seeking smoother, gamified blockchain experiences.

Performance and Market Sentiment

Price action also favors Sui. While Solana bounced impressively from its post-FTX lows, Sui is now showing similar potential—with infrastructure support, developer traction, and consumer-facing products driving upward momentum.

The market seems to agree. Multiple indicators suggest Sui could outperform both Solana and Ethereum in the upcoming cycle. Its lower starting valuation also offers more upside, especially for value investors looking for the “next Solana.”

Final Thoughts

While it’s too early to crown Sui the definitive winner, all signs point to a strong L1 contender. Between integrations, product expansion, and market sentiment, Sui is carving a path worth watching—and potentially investing in.
