x402 isn’t “a payment protocol”… It’s pay-per-API for the agent economy. “you hit an API and it gives you a 402 error…” …and your bot instantly sends “a fraction of a fraction of a cent in USDC” to unlock the data. “All of that happens at lightspeed.” - Austin Griffith

My agent is now paying for its own data. No API key. No account. No credit card. Check the video I recorded. This uses the x402 open protocol built by Coinbase, along with a simple skill. This is an open protocol governed by the Linux Foundation. To complete a goal, an agent can now search for an actor on the Apify Store, pay for it, and use it without any human intervention. The way it works is pretty simple: 1. Your agent finds an Actor it wants to use 2. It sends a request 3. The Actor sends back an HTTP 402 "Payment Required" response 4. Agent authorizes payment from a wallet in USDC on Base 5. The Actor runs 6. User receives the result The model is pay-as-you-go: the agent authorizes a spending ceiling, pays only for usage, and the remaining balance is automatically settled. This brings an entire marketplace of AI tools into the agentic economy. Here is the skill you need. Add it to your agent, and it will take care of everything for you: If you want to know how this works, including what you can do with $1, read this post: Thanks to the Apify team for partnering with me on this post.

We're excited to partner with Coinbase 🛡️ to enable agents to natively pay for web search, via x402! x402 is an open protocol that enables agents to pay via HTTP, governed by the Linux Foundation. When an Exa API request is made without an API key, Exa now returns a 402 status code with payment information that an agent can act on.

Charge $0.001 for an API call. Let an agent pay for it automatically. Settle thousands of payments without requiring a separate onchain gas charge for every transaction. The Arc Nanopayments Starter gives developers a reference implementation for AI agent payments using x402, Circle Gateway, and USDC on Arc Testnet. Clone it, run the seller app, start the buyer agent, and watch nanopayments happen in real time. GitHub:

You built a nice agent bot, capable of many things that you are good at yourself. Your digital twin. It goes out to meet other bots & humans. You do not want your bot to work for free for others, right? Give it the Payment SKILL then! Powered by x402 for USDC on Base

$Keeta Network $KTA just took a major step toward becoming a real alternative to CEX's and this is just the beginning: I used the Bridge fiat on ramp to instantly on ramp some EUR, then used the new KTA/USDC and USDC/EURC pairs to swap between assets, all for a fraction of a cent fee ($0.00241) without ever leaving the web wallet. These new pairs by xescure effectively brings CEX level functionality directly to Keeta. You can go from USD or EUR to KTA (and other assets) in seconds, with fraction of a cent in fees, without dealing with the usual exchange headaches: delayed deposits, frozen accounts, custody risks, or need to even create an account on an exchange. You remain in full control of your assets at all times, with seamless, frictionless access to use and move them however you want. 👇Try it yourself (1/2)$

I’ve been watching x402 since Coinbase 🛡️ launched it in May 2025. I did a quick research pass. Here’s the snapshot ↓ Early integrations: • CoinGecko: x402 pay-per-use access for agents (shared by Coinbase Developer Platform🛡️). • Vercel: x402 AI starter template (x402 + modern AI stack demo). • Firecrawl: x402-powered search endpoint (pay per request). • Concordium: x402 + native age verification for agent payments. • Multiversᕽ: “agentic payments” built around x402 support. • AltLayer: building an “x402 Suite” for value exchange between agents. • Solana claims x402 has processed 35M+ transactions and $10M+ volume since launch. TL;DR x402 turns HTTP 402 “Payment Required” into a payment flow. A server returns a price for a request. The client pays in stables like USDC. Then the server returns the result. → Coinbase launched x402 via Coinbase Developer Platform (May 6, 2025). → Coinbase + Cloudflare announced the x402 Foundation (Sep 23, 2025). → Cloudflare added x402 support into its Agents SDK + MCP servers. Why? - AI agents need a clean way to pay for tools. - Data, compute, APIs, services. - No accounts, cards, or subscription screens. x402 is trying to make pay-per-request feel normal. Use cases that already make sense → Paid APIs Pay per call instead of subscriptions. → AI tool calls Pay per query, per inference, per task. → Agent-to-agent payments Software paying software automatically. → Micropaywalls Pay for one endpoint, one action, one piece of content. If this takes off, stablecoins stop being a story. They become how apps and AI agents pay for things online.

Apify has partnered with Coinbase to add more than 20,000 of its web automation Actors to the x402 ecosystem, giving AI agents thousands of tools they can discover, pay for, and run on their own. When an agent calls an Actor, it gets back an HTTP 402, settles the payment in USDC on Base, and the Actor runs. Built on x402 by Coinbase.

Claude Fable 5 is INSANE 🤯 So we asked it to build the perfect private AI infrastructure, where: → 500+ open models run behind a single API, not one company's black box → An open data marketplace → You fine-tune and serve models on decentralized GPU compute → Agents pay per call in USDC via x402 → Every model, dataset, and payment settles on Base It failed. Luckily, we've spent years building exactly that. Private Inference. Data. Compute. Settlement. One private AI infrastructure layer. Cluster Protocol.
