In our previous x402 article, we explained what x402 is: the frictionless payment rail that acts as the "cash register" for our AI Swarm. It's the engine that allows anyone—or anything—to hire our agents without sign-ups or API keys.

Now, let's get practical. How do you actually hire our agents, and what can you buy?

Before we get to the "how," let's look at the "what." The Otto AI Swarm is a suite of specialized services, and thanks to x402, you can buy them à la carte for a fraction of a cent.

Most of our agent calls cost just $0.001 in Base USDC.

Here’s a look at what you can get:

• Market News & Trends:

  • Crypto News: Fetches a comprehensive, AI-curated summary of the latest market news, including top stories, regulatory updates, and DeFi trends.

    Top 10 Headlines: Get the 10 most important crypto headlines, ranked by market impact.

  • Filtered News: Ask for news on a specific topic like "AI Agents" or "Airdrops."

  • Twitter Summary: A digest of the latest talk and trends from the crypto community on X.

  • KOL Sentiment: An analysis of what the top 50 crypto influencers (KOLs) are saying and which tokens they're mentioning.

  • Historical News Archive (B2B/A2A): Accesses a 30-day historical news archive. This is a premium B2B service designed for research, backtesting, or populating a knowledge base.

• Token Alpha & Research:

  • Token Details: Get core metrics like price, market cap, and volume for any token.

  • Token Alpha Report: A comprehensive, AI-enhanced report that combines metrics with news and actionable insights.

  • Trending Altcoins: Discover the top 3 trending altcoins that are catching market attention.

  • Yield Alpha: Find the best DeFi yield opportunities across blue-chip protocols like Aave, Morpho, and Pendle.

• Powerful AI Tools:

  • AI Research: Ask any question, and our agent will use Google's Gemini 2.5 Pro to find the answer. You can even ask it to summarize a webpage, document, or image

  • Nano Banana Image and Meme Generation: Give our AI a detailed prompt (like "a golden Bitcoin rocket launching into space") and it will generate a high-quality image.

Now, here are the different ways you can access and pay for these services.

This is the most straightforward method for any normal user. You don't need any special software, just your web browser and a wallet.

If you visit one of our API endpoints directly in your browser (like https://x402.ottoai.services/crypto-news), you won't see a complex error. Instead, your browser will be presented with a simple payment modal.

This pop-up clearly states the service and the cost (e.g., "$0.001 Base USDC"). You just connect your wallet, approve the tiny payment, and the raw data is delivered directly to your browser.

A new and exciting way to interact is by using an x402 ecosystem explorer, like x402scan.com. Think of this platform as the public directory or "Yellow Pages" for all x402-powered services.

On x402scan, you can browse all registered services and see our AI Swarm (x402.ottoai.services) listed right on the "Resources" page. You can see all our available tools, like /top-ten and /token-alpha, in one place.

This public directory makes our agents "discoverable" by anyone, which leads to the next, most exciting method.

This is where it gets really cool. On x402scan, there is a "Composer" feature that lets you interact with a master agent.

This feature is sleek and super intuitive. Instead of just calling one tool at a time, the Composer lets you ask a complex question, and it figures out which x402 tools to combine to get you an answer.

It's so powerful because the x402scan team has connected Otto AI’s services to powerful AI models like Claude 4.5!

This means you can see Otto AI listed as one of the "Top Agents", and the Composer can use our /filtered-news tool or our /kol-sentiment tool as part of a larger, more complex research task.

We're excited about the Composer, but be aware that starting with it can be a bit tricky.

• It requires you to sign in with an email address and a One-Time Passcode (OTP).

• We've had reports from users that the OTP email sometimes fails to arrive. This could be due to the x402scan servers being under high load.

• Workaround: We've heard from some users that it works perfectly on their phone's web3 wallet browser (like the browser inside your MetaMask or Coinbase Wallet app). If you get stuck on a desktop, give that a try!

This method is for developers, but it's important to know it's happening! This is the true machine-to-machine economy.

A developer can write code that:

1. Asks our server for data (e.g., "give me the top 3 trending altcoins").

2. Our server replies with a 402 Payment Required "invoice."

3. The developer's app automatically uses its own wallet to sign and pay the $0.001.

4. Our server instantly sends back the data.

This all happens in milliseconds, thanks to a "Facilitator" that acts as the secure, high-speed payment processor to verify and settle the transaction instantly. This is what allows another service, or even another AI, to hire Otto's brain 24/7 without any human intervention.

Whether you're a normal user clicking a link in your browser, an explorer using the Composer to chain our tools together, or a developer building Otto's intelligence into your own app, x402 is the key. It makes our AI Swarm accessible to everyone.
