What You Will Learn — Two-Paragraph Opener

This tutorial shows you how to use x402 with Token Metrics in two ways. First, we will walk through x402 Composer, where you can run Token Metrics agents, ask questions, and see pay-per-request tool calls stream into a live Feed with zero code. Second, we will give you copy-paste Axios and HTTPX clients that handle the full x402 flow (402 challenge, wallet payment, automatic retry) so you can integrate Token Metrics into your own apps.

Whether you are exploring x402 for the first time or building production agent workflows, this guide has you covered. By the end, you will understand how x402 payments work under the hood and have working code you can ship today. Let's start with the no-code option in Composer.

Start using Token Metrics X402 integration here. https://www.x402scan.com/server/244415a1-d172-4867-ac30-6af563fd4d25 

Part 1: Try x402 + Token Metrics in Composer (No Code Required)

x402 Composer is a playground for AI agents that pay per tool call. You can test Token Metrics endpoints, see live payment settlements, and understand the x402 flow before writing any code.

What Is Composer?

Composer is x402scan's hosted environment for building and using AI agents that pay for external resources via x402. It provides a chat interface, an agent directory, and a real-time Feed showing every tool call and payment across the ecosystem. Token Metrics endpoints are available as tools that agents can call on demand.

Explore Composer: https://x402scan.com/composer

Step-by-Step Walkthrough

Follow these steps to run a Token Metrics query and watch the payment happen in real time.

  1. Open the Composer agents directory: Go to https://x402scan.com/composer/agents and browse available agents. Look for agents tagged with "Token Metrics" or "crypto analytics." Or check our our integration here. https://www.x402scan.com/server/244415a1-d172-4867-ac30-6af563fd4d25 
  2. Select an agent: Click into an agent that uses Token Metrics endpoints (for example, a trading signals agent or market intelligence agent). You will see the agent's description, configured tools, and recent activity.
  3. Click "Use Agent": This opens a chat interface where you can run prompts against the agent's configured tools.
  4. Run a query: Type a question that requires calling a Token Metrics endpoint, for example "Give me the latest TM Grade for Ethereum" or "What are the top 5 moonshot tokens right now?" and hit send.
  5. Watch the Feed: As the agent processes your request, it will call the relevant Token Metrics endpoint. Open the Composer Feed (https://x402scan.com/composer/feed) in a new tab to see the tool call appear in real time with payment details (USDC or TMAI amount, timestamp, status).

 

Composer agents directory: Composer Agents page: Each agent shows tool stack, messages, and recent activity.

 

Individual agent page: Agent detail page: View tools, description, and click "Use Agent" to start.

[INSERT SCREENSHOT: Chat interface]

Chat interface: Chat UI: Ask a question like "What are the top trading signals for BTC today?"

[INSERT SCREENSHOT: Composer Feed]

Composer Feed: Live Feed: Each tool call shows the endpoint, payment token, amount, and settlement status.

That is the x402 flow in action. The agent's wallet paid for the API call automatically, the server verified payment, and the data came back. No API keys, no monthly bills, just pay-per-use access.

Key Observations from Composer

  • Tool calls show the exact endpoint called (like /v2/tm-grade or /v2/moonshot-tokens)
  • Payments display in USDC or TMAI with the per-call cost
  • The Feed updates in real time, you can see other agents making calls across the ecosystem
  • You can trace each call back to the agent and message that triggered it
  • This is how agentic commerce works: agents autonomously pay for resources as needed

Part 2: Build Your Own x402 Client (Axios + HTTPX)

Now that you have seen x402 in action, let's build your own client that can call Token Metrics endpoints with automatic payment handling.

How x402 Works (Quick Refresher)

When you make a request with the x-coinbase-402 header, the Token Metrics API returns a 402 Payment Required response with payment instructions (recipient address, amount, chain). Your x402 client reads this challenge, signs a payment transaction with your wallet, submits it to the blockchain, and then retries the original request with proof of payment. The server verifies the settlement and returns the data. The x402-axios and x402 Python libraries handle this flow automatically.

Prerequisites

  • A wallet with a private key (use a testnet wallet for development on Base Sepolia, or a mainnet wallet for production on Base)
  • USDC or TMAI in your wallet (testnet USDC for testing, mainnet tokens for production)
  • Node.js 18+ and npm (for Axios example) or Python 3.9+ (for HTTPX example)
  • Basic familiarity with async/await patterns

Recommended Token Metrics Endpoints for x402

These endpoints are commonly used by agents and developers building on x402. All are pay-per-call with transparent pricing.

Full endpoint list and docs: https://developers.tokenmetrics.com 

Common Errors and How to Fix Them

Here are the most common issues developers encounter with x402 and their solutions.

Error: Payment Failed (402 Still Returned After Retry)

This usually means your wallet does not have enough USDC or TMAI to cover the call, or the payment transaction failed on-chain.

  • Check your wallet balance on Base (use a block explorer or your wallet app)
  • Make sure you are on the correct network (Base mainnet for production, Base Sepolia for testnet)
  • Verify your private key has permission to spend the token (no allowance issues for most x402 flows, but check if using a smart contract wallet)
  • Try a smaller request or switch to a cheaper endpoint to test

Error: Network Timeout

x402 requests take longer than standard API calls because they include a payment transaction. If you see timeouts, increase your client timeout.

  • Set timeout to at least 30 seconds (30000ms in Axios, 30.0 in HTTPX)
  • Check your RPC endpoint is responsive (viem/eth-account uses public RPCs by default, which can be slow)
  • Consider using a dedicated RPC provider (Alchemy, Infura, QuickNode) for faster settlement

Error: 429 Rate Limit Exceeded

Even with pay-per-call, Token Metrics enforces rate limits to prevent abuse. If you hit a 429, back off and retry.

  • Implement exponential backoff (wait 1s, 2s, 4s, etc. between retries)
  • Spread requests over time instead of bursting
  • For high-volume use cases, contact Token Metrics to discuss rate limit increases

Error: Invalid Header or Missing x-coinbase-402

If you forget the x-coinbase-402: true header, the server will treat your request as a standard API call and may return a 401 Unauthorized if no API key is present.

  • Always include x-coinbase-402: true in headers for x402 requests
  • Do not send x-api-key when using x402 (the header is mutually exclusive)
  • Double-check header spelling (it is x-coinbase-402, not x-402 or x-coinbase-payment)

Production Tips

  • Use environment variables for private keys, never hardcode them
  • Set reasonable max_payment limits to avoid overspending (especially with TMAI)
  • Log payment transactions for accounting and debugging
  • Monitor your wallet balance and set up alerts for low funds
  • Test thoroughly on Base Sepolia testnet before going to mainnet
  • Use TMAI for production to get the 10% discount on every call
  • Cache responses when possible to reduce redundant paid calls
  • Implement retry logic with exponential backoff for transient errors

Why This Matters for Agents

Traditional APIs force agents to carry API keys, which creates security risks and requires human intervention for key rotation and billing. With x402, agents can pay for themselves using wallet funds, making them truly autonomous. This unlocks agentic commerce where AI systems compose services on the fly, paying only for what they need without upfront subscriptions or complex auth flows.

For Token Metrics specifically, x402 means agents can pull real-time crypto intelligence (signals, grades, predictions, research) as part of their decision loops. They can chain our endpoints with other x402-enabled tools like Heurist Mesh (on-chain data), Tavily (web search), and Firecrawl (content extraction) to build sophisticated, multi-source analysis workflows. It is HTTP-native payments meeting real-world agent use cases.

FAQs

Can I use the same wallet for multiple agents?

Yes. Each agent (or client instance) can use the same wallet, but be aware of nonce management if making concurrent requests. The x402 libraries handle this automatically.

Do I need to approve token spending before using x402?

No. The x402 payment flow uses direct transfers, not approvals. Your wallet just needs sufficient balance.

Can I see my payment history?

Yes. Check x402scan (https://x402scan.com/composer/feed) for a live feed of all x402 transactions, or view your wallet's transaction history on a Base block explorer.

What if I want to use a different payment token?

Currently x402 with Token Metrics supports USDC and TMAI on Base. To request support for additional tokens, contact Token Metrics.

How do I switch from testnet to mainnet?

Change your viem chain from baseSepolia to base (in Node.js) or update your RPC URL (in Python). Make sure your wallet has mainnet USDC or TMAI.

Can I use x402 in browser-based apps?

Yes, but you will need a browser wallet extension (like MetaMask or Coinbase Wallet) and a frontend-compatible x402 library. The current x402-axios and x402-python libraries are designed for server-side or Node.js environments.

Mastering Binance & Coinbase APIs for Automated Crypto Trading

Token Metrics Team
6

Automating crypto trading with APIs is revolutionizing how traders and developers interact with digital asset markets. If you've ever wondered how to connect directly to exchanges like Binance and Coinbase, automate your strategies, or build your own trading bots, understanding their APIs is the crucial first step. This guide unpacks the essentials of using the Binance and Coinbase APIs for automated crypto trading—explaining the technology, potential use cases, and important considerations for getting started.

What Are Crypto Trading APIs?

APIs, or Application Programming Interfaces, enable software to interact directly with external services. Within cryptocurrency trading, APIs provide a standardized way for users and programs to connect with exchange platforms, fetch market data, execute trades, manage portfolios, and access account information programmatically.

  • Market Data: Real-time and historical prices, order books, trade volume, and related metrics.
  • Order Placement: Automated buying/selling, stop-loss, take-profit, and other order types.
  • Account Management: Retrieve balances, view transaction history, or monitor active positions and orders.

This seamless integration supports the development of sophisticated trading strategies, algorithmic trading bots, portfolio trackers, and research analytics. The most widely adopted crypto trading APIs are those offered by Binance and Coinbase, two of the largest global exchanges.

Getting Started with Binance API Trading

Binance’s API is well-documented, robust, and supports diverse endpoints for both spot and futures markets.

  1. Create Your Binance Account: Ensure that your account is verified. Navigate to the Binance user center and access the API Management section.
  2. Generate API Keys: Label your key, complete security authentication, and note both your API key and secret. Keep these credentials secure and never share them publicly.
  3. API Permissions: Explicitly select only the API permissions needed (e.g., read-only for analytics, trading enabled for bots). Avoid enabling withdrawal unless absolutely necessary.
  4. Endpoints: The Binance REST API covers endpoints for market data (public), and trading/account management (private). It also offers a WebSocket API for real-time streams.

Popular use cases for Binance API trading include automated execution of trading signals, quantitative strategy deployment, and real-time portfolio rebalancing. The official documentation is the go-to resource for development references. Consider open-source SDKs for Python, Node.js, and other languages to streamline integration.

Unlocking the Power of the Coinbase API

Coinbase provides comprehensive APIs for both its retail platform and Coinbase Advanced Trade (previously Coinbase Pro). These APIs are favored for their security and straightforward integration, especially in regulated environments.

  1. API Creation: Log in to your Coinbase account, go to API settings, and generate an API key. Set granular permissions for activities like account viewing or trading.
  2. Authentication: The Coinbase API uses a combination of API key, secret, and passphrase. All API requests must be authenticated for private endpoints.
  3. Endpoints & Features: The API allows retrieval of wallet balances, transaction histories, live price data, and supports programmatic trading. The Coinbase API documentation offers detailed guides and SDKs.

Use the Coinbase API for automated dollar-cost averaging strategies, portfolio analytics, or to connect external research and trading tools to your account. Always apply IP whitelisting and two-factor authentication for heightened security.

Key Challenges and Considerations in Automated Crypto Trading

While APIs empower sophisticated trading automation, several technical and strategic considerations should be addressed:

  • API Rate Limits: Both Binance and Coinbase restrict the number of API calls per minute/hour. Exceeding limits can lead to throttling or IP bans, so efficient coding and request management are essential.
  • Security First: Secure storage of API keys, use of environment variables, and permission minimization are vital to prevent unauthorized access or loss of funds.
  • Handling Market Volatility: Automated trading bots must account for slippage, API latency, and unexpected market events.
  • Testing Environments: Utilize the exchanges’ testnet or sandbox APIs to validate strategies and avoid live-market risks during development.

For more complex strategies, combining data from multiple APIs—including on-chain analytics and AI-powered research—can provide deeper insights and help navigate uncertain market conditions.

Leveraging AI and Advanced Analytics for Crypto API Trading

The real advantage of programmatic trading emerges when combining API connectivity with AI-driven analytics. Developers can harness APIs to fetch live data and feed it into machine learning models for signal generation, anomaly detection, or portfolio optimization. Tools like Python’s scikit-learn or TensorFlow—paired with real-time data from Binance, Coinbase, and third-party sources—enable dynamic strategy adjustments based on shifting market trends.

AI agents and intelligent trading bots are increasingly built to interface directly with crypto APIs, processing complex data streams to execute trades or manage risk autonomously. Such systems benefit from robust backtesting, frequent monitoring, and a modular design to ensure security and compliance with exchange requirements.

FAQ: How Do Binance and Coinbase APIs Compare?

Both Binance and Coinbase offer REST APIs, but Binance has broader asset coverage and advanced trading features, including futures and options support. Coinbase’s APIs prioritize security, are well-suited for U.S. users, and offer streamlined integration for both spot and advanced trade scenarios.

FAQ: What Programming Languages Can Be Used for Crypto Trading APIs?

Python, JavaScript/Node.js, and Java are the most popular choices for building automated trading bots due to the availability of SDKs and community support. Most modern APIs are RESTful and compatible with any language that can perform HTTP requests.

FAQ: How Do I Keep My API Keys Secure?

Best practices include storing API keys in environment variables, never exposing them in source code repositories, limiting permissions, and regularly rotating keys. Also, use IP whitelisting and two-factor authentication if supported by the exchange.

FAQ: Can I Use Multiple Exchange APIs Together?

Yes. Many advanced traders aggregate data and trade across several exchange APIs to increase liquidity access, compare prices, or diversify strategies. This often requires unifying different API schemas and handling each exchange’s unique rate limits and authentication protocols.

FAQ: What Are the Risks of Automated Trading with Crypto APIs?

Automated trading can lead to unintended losses if there are bugs in the code, API changes, or sudden market movements. Proper error handling, backtesting, and initial development in sandbox/testnet environments are key risk mitigation steps.

Mastering Crypto Trading Bots: DCA, Grid, Arbitrage Strategies Explained

Token Metrics Team
6

Crypto trading bots have transformed how traders and analysts approach the fast-moving digital assets market. With a variety of automated strategies—like Dollar Cost Averaging (DCA), grid trading, and arbitrage—these bots help users implement consistent, rules-based tactics around the clock. But understanding how each strategy works, their strengths and limitations, and the technology that powers them is crucial for anyone looking to utilize automation in crypto trading.

What Are Crypto Trading Bots?

Crypto trading bots are software programs designed to automate trading decisions based on predefined criteria and algorithms. These tools connect to crypto exchanges via API, executing trades according to parameters set by the user or the strategy's logic. The goal isn’t to guarantee profit, but to implement systematic, emotion-free trading practices at speed and scale impossible for humans alone.

Common features among top crypto trading bots include:

  • Backtesting: Testing strategies against historical market data.
  • Multi-exchange support: Managing orders across several platforms simultaneously.
  • Customization: Adjusting trading frequency, risk management, and strategy rules.
  • Real-time analytics: Providing insights on bot performance and market trends.

With AI and advanced analytics, bots now utilize sophisticated signals—from price action to on-chain data—to further enhance decision-making.

Exploring Dollar Cost Averaging (DCA) Bots

Dollar Cost Averaging (DCA) is a foundational investing concept, and DCA bots automate its application in the crypto markets. The DCA strategy involves purchasing a set amount of cryptocurrency at regular intervals, irrespective of price fluctuations. This method reduces exposure to volatility and removes the need to time market tops or bottoms.

A DCA bot performs these actions by connecting to your chosen crypto exchange and placing periodic orders automatically. Customizable options include:

  • Frequency (e.g., daily, weekly, monthly)
  • Order size and asset choice
  • Advanced features: stop-loss, take-profit settings, or integration with technical indicators

Scenario analysis: For long-term market participants, DCA bots can smooth out entry prices during periods of high volatility, especially in trending or sideways markets. However, DCA does not prevent losses in downtrending markets and might not be optimal for short-term speculation.

Many platforms offer DCA bots, and some combine DCA with AI-driven market indicators, offering more nuanced deployment. Tools like Token Metrics provide research that can help users evaluate when and how to use DCA strategies alongside their risk management framework.

How Grid Trading Bots Work

Grid trading bots are designed to profit from price oscillations within a defined range by placing a series of buy and sell orders at predetermined intervals (the "grid"). As the market moves, the bot buys low and sells high within this corridor, striving to capture profits from repeated fluctuations.

Key components of a grid trading bot:

  • Selection of price range and grid step size
  • Automated placement of buy orders below the current market price and sell orders above
  • Dynamic grid adjustment (optional in advanced bots) in response to significant volatility or trend shifts

Grid trading is best suited for markets with horizontal price movement or mild volatility. It may underperform during strong trends (up or down) as the price moves outside the set grid.

To optimize grid performance, traders often analyze historical price ranges, volatility indices, and liquidity metrics—processes where AI tools and platforms like Token Metrics can provide data-driven insights to fine-tune grid parameters.

Understanding Arbitrage Bots in Crypto

Arbitrage is the practice of exploiting price differences of the same asset across different exchanges or markets. Arbitrage bots automate the process, rapidly identifying and capitalizing on even small price discrepancies before the market corrects itself.

There are several types of crypto arbitrage:

  • Spatial Arbitrage: Buying on one exchange and selling on another.
  • Triangular Arbitrage: Trading between three assets/exchanges to capture pricing inefficiencies.
  • DeFi Arbitrage: Leveraging decentralized exchanges, liquidity pools, or lending platforms for profit opportunities.

Arbitrage bots require:

  • Low latency and rapid execution
  • Reliable API integrations with multiple exchanges
  • Fee and slippage calculation to prevent unprofitable trades

While arbitrage opportunities exist in crypto due to market fragmentation and varying liquidity, increased competition and improved exchange efficiency have narrowed average profit margins. Bots are now often paired with on-chain analytics or machine learning models to anticipate emerging inefficiencies.

Selecting and Optimizing Crypto Trading Bot Strategies

Not all strategies suit all market conditions. Choosing and optimizing a crypto trading bot strategy involves:

  • Market context: Are market conditions trending, sideways, or highly volatile?
  • Risk profile: What level of drawdown, maximum investment, and potential trade frequency is acceptable?
  • Backtesting & simulation: Most platforms allow testing strategies on historical data or with paper trading, supporting more informed choices.

Advanced users often create hybrid strategies—such as combining DCA for accumulation with a grid bot for ranging periods, or adding arbitrage layers where price disparities appear. AI-based research solutions can help proactively monitor correlations, identify volatility shifts, and surface emerging patterns, providing analytical depth to trading bot strategy selection.

Before using any trading bot or automated strategy, it is essential to understand the underlying logic, risk controls, and limitations. Start with small amounts, test thoroughly, and review available documentation and analytics from trusted platforms.

FAQ: Crypto Trading Bots, DCA, Grid & Arbitrage

What types of assets can crypto trading bots handle?

Most crypto trading bots can support major coins (Bitcoin, Ethereum) and numerous altcoins, depending on the exchanges and APIs integrated. Liquidity and exchange pairs may limit available strategies for smaller tokens.

How do trading bots connect with exchanges?

Bots use APIs provided by exchanges to access trading accounts and execute orders automatically. API permissions usually allow for account security by limiting withdrawal capabilities to prevent misuse.

Are DCA bots better than grid or arbitrage bots?

No single strategy is universally better; each suits different market conditions and goals. DCA aims to reduce volatility impact, grid bots thrive in ranging markets, and arbitrage bots seek price discrepancies across platforms.

Can AI improve automated trading strategies?

AI can enhance trading bots by analyzing large datasets, identifying patterns, and generating trading signals based on market sentiment, technical factors, or on-chain activity. Platforms like Token Metrics integrate AI-driven analytics for more informed strategy design and monitoring.

What are the key risks in using crypto trading bots?

Risks include technological errors, unexpected market volatility, slippage, API downtime, and exchange limitations. It is important to monitor bot activity, use strong security practices, and test any automated strategy before deploying significant capital.
