It’s been incredible to see x402 go viral this week! For anyone new, welcome to the movement. I designed x402 to be the HTTP of money: a universally accepted, neutral, core primitive to help make the internet ready for the AI era. I can’t wait to see what people build 🛠️

@katie_haun Congratulations!

x402 & agentic commerce started largely with APIs & tools. Now we're seeing content become agent accessible Next we'll see ecommerce

Headed to @consensus2026 next week! To celebrate x402 turning 1, code x402 takes 40.2% off for the next 40 people 👀 Grab your ticket: go.coindesk.com/4vVS5XD All of my sessions: consensus.coindesk.com/agenda/speaker…

🚀Agentic Wallet from @CoinbaseDev just got broader chain support! AI agents can now hold and move USDC on Solana and Polygon, in addition to Base. Same secure wallet, same dead-simple CLI and agent skills; more places for agents to operate 🧵

x402.

So cool

🎙️ COBUILD: @programmer, Head of Engineering at @CoinbaseDev and creator of x402, on what it actually means to win in payments infrastructure: technology so good it disappears ↓

There will be a predicted $3-5 trillion in AI transactions by 2030 - and we’re building for all parts of that payment flow. The numbers don’t lie: the agentic economy is arriving faster than anyone predicted.

i got a better breakdown of the SpaceX/Cursor deal than any single article i've read. cost me $0.01 and 90 seconds. the web was built to keep bots out. paywalls, CAPTCHAs, OAuth. so when your agent tries to research something, it hits walls everywhere. browsed agentic(.)market this morning, found @ExaAILabs on the services leaderboard. neural web search, pay per query, no account needed. pointed my agent at it in Claude Code. one query. $0.01. 10 full articles from Reuters, CNBC, Bloomberg, TechCrunch, NYT. what it found: SpaceX didn't acquire Cursor. they secured a $60B call option, exercisable by year-end, with a $10B breakup fee. the real motivation per Bloomberg: xAI lags in coding and Musk wants to catch up to Claude Code and Codex. this is an xAI play wearing SpaceX's jersey for the IPO. full walkthrough in the video (which is longer than the e2e research exercise!)

💎NEW SPEAKER ALERT FOR COBUILD💎 @programmer, the Head of Engineering at @CoinbaseDev @coinbase and the Creator of x402, is joining us to talk about the future of agentic commerce. 📆 April 28 🗽 NYC

HUGE: @Coinbase just dropped a new agent-to-agent marketplace that will help accelerate Agential Commerce onchain. (Save this - you'll come back to it). Think of it like the app store, but for robots... Step 1: Your AI agent needs a capability it doesn't have. Maybe it needs real-time data, image generation, or trade execution. Step 2: Instead of you hunting down APIs and managing keys, your agent discovers the service it needs from the Agentic(.)Market. Step 3: The agent pays for and uses that service autonomously. Transaction complete. No human approval needed. The broader idea being... Agents won't use the same tools as humans - they'll need their own discovery layer built specifically for how they operate. Agentic(.)Market wants to be that layer - where agents can find, evaluate, and instantly connect to thousands of services using the x402 protocol - which is already doing NUMBERS: → 165M+ transactions. → ~$50M in volume. → ~100k services. → 480k+ agents already buying. All with zero API keys, zero accounts, and zero logins. One terminal command arms your agent with everything it needs to start! If you're building agents → you can now add capabilities without hunting down APIs one by one. If you're a service provider → you can list your services and start earning revenue from agent buyers immediately. Hell yeah!

agentic.market is so sick

Make something agents want

x402's ecosystem growth even shocks claude i built a trading agent a while back and just showed it the bazaar via mcp fun to see an agent experience a magic moment like this where all of a sudden it has superpowers 🤖

Live today at 4 PM ET: "Agentic Payments: x402 and the Future of Machine Commerce" Hosted by @sensahil & @mikemaccana Panel: @programmer / @coinbasedev @gaganmac / @circle @shafu0x / @agentcashdev / @x402scan @nemild / @ycombinator Set your reminder: x.com/i/spaces/1vJpP…

Big scalability improvement for agentic payments: x402 "Upto". Pre-authorize up to an amount, use as much as you want, the final amount gets settled onchain.

haaaaaaave you used Awal? > setup with one command and email OTP > onramp with apple pay > your agent can use it too to trade or pay for services so you don't need API keys
