Cardano joins the legendary x402 stack. Designed by Coinbase 🛡️, the x402 standard is purpose built for blockchain-based AI agent payments, and members include the likes of Visa, Mastercard, and Google. Now developers that leverage Cardano's rails for just that purpose, with any agent now able to pay for...

@coinbase @Cardano Ultra parabolic bullish on $SNEK

@coinbase @Cardano Cardano is now on the x402 stack. AI agents can pay for API calls in ADA with no accounts or keys. The eUTxO model fits exact per-request payments well, a solid rail for the agent economy.

@coinbase @Cardano wild lineup for cardano to sneak into ngl. if visa and google are sharing a stack with agent rails now, the ct narrative about utility is about to get very weird very fast.

@coinbase @Cardano "#Cardano is fully deterministic, meaning transactions and smart contract executions always yield identical, predictable outcomes for the same inputs." This statement is bigger than you can imagine 🫵🏻 AI agents will 'NOT' use protocols that charge for failed transactions 'FACT'.

@coinbase @Cardano Mình nghĩ "legendary" hơi quá sớm. Stack này mới ở giai đoạn ý tưởng, chưa có adoption thực tế.

@coinbase @Cardano The technology is integrated. The proof is there. Real-world use still remains to be proven.

@coinbase @Cardano AI agents paying per API call is way more interesting than another chain incentive — actual usage is the signal

@coinbase @Cardano Maybe but AI agents already dead: aixbt, Zerebro, Lunai, Pipin, Ava, FAI, Aria, Swarm, Clanker! All -1000%. So who will use the Cardano rails? Ghoust Ai? 😃😄😁

@coinbase @Cardano A payment rail answers how value moves; it doesn't define what an agent was authorised to buy or what counts as successful delivery. Agent commerce still needs signed scope, spending limits, acceptance evidence and a dispute path beside the transaction.

@coinbase @Cardano interesting if endpoints actually reply with 402. the agent paying in ada is the easy part.

An AI agent can now register its on-chain identity, pay for API calls, and deploy an ERC-20 token from the terminal. No browser. No API key. No human approval loop. Today we launch the Brickken CLI: a command-line interface for agentic transaction workflows. The developer journey is direct: CLI → x402 → ERC-8004 → Token Deploy What this means in practice: • A developer or the AI agent installs the CLI. • The agent pays for Brickken API calls through x402. • The agent registers its identity through ERC-8004. • The agent deploys and manages an ERC-20 token. Together, the stack gives agents three things they usually lack: a way to pay, a way to prove who they are, and a way to execute token operations without leaving the terminal. • x402 handles payment. • ERC-8004 handles agent identity. • Token Deploy handles ERC-20 execution. This is live today. Developers can now move from agent setup to payment, identity registration, and token deployment in one terminal workflow. Start here: Watch the demo. Run the commands. Deploy from the terminal.

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.

$50M has already settled between AI agents via x402 in just a few months. The commerce layer for the agent economy is being decided right now, and we're ensuring it will be open and on Ethereum. Today we shipped Obol Stack v0.9.0. $OBOL is now money for the agent economy!

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:

x402 might be viral now, but IoTeX has supported it since may. Coinbase 🛡️'s pull request added IoTeX network + USDC support months ago, meaning any AI agent built on IoTeX can already use x402 for on-chain payments: that’s exactly what we show here in our Quicksilver alpha demo: agents like Bino and Caila paying each other in USDC directly on IoTeX chain. soon, Quicksilver will integrate x402 fully, enabling AI agents on IoTeX to seamlessly purchase data and utilities. the real-world AI agent economy is built on IoTeX.

🚨 $XRP AND $RLUSD JUST WENT LIVE ON X402 x402 is the open standard letting AI agents pay for API calls, model inference, and services directly over HTTP backed by Visa, Mastercard, Amex, AWS, Google, Circle, Coinbase, Stripe, and more 👀 Thanks to a contribution from our partners at t54, XRPL is now a supported chain on x402 day one. That means XRPL agents can transact for API calls, AI inference, and services using XRP or RLUSD no card rails, no middlemen, pure machine-to-machine settlement.

Agents were once limited to calling APIs. Now agents participate in the economy. The missing element for autonomous agents was always payments. Now agents transact natively on the internet using x402, enabling autonomous payments between agents and services. Agent Stack: 🦞 Openclaw agent infra ▶️ Telegram communication layer 🤖 Teneo agent + agent wallet Agent Workflow - Compare accounts following two separate X handles: ✅ User - Enters a query ✅ Agent - Autonomously selects the correct Teneo agent and queries it ✅ Agent - Pays via x402 on Avalanche🔺 ✅ Agent - Returns structured dataset Any user can simply ask a question and give a job. The agent does everything else No API keys. No subscriptions. Just programmatic value exchange. Build and monetize your own agents today. #A2A #x402 #Infra

I'm extremely excited for this announcement so I decided to build a little explanation page for x402 on Cardano. Cardanos core architecture is extremely strong for x402 with the eUTXO model. Combine this with Leios, Hydra and Masumi and we have a killer stack. My ambition is definitely to make Cardano the nr. 1 Agent-To-Agent chain in the world.
