Everyone's talking about AI agents. Very few people are building the rails for how they'll actually pay for things. @louisamira left Stripe - where he was the first external crypto hire and helped shape the strategy behind the Bridge and Privy acquisitions - to co-found Circuit & Chisel and build @atxp_ai, the protocol he calls HTTP for agentic payments. $19.2M seed led by @PrimaryVC and @paraficapital, with participation from @stripe, @cbventures, and @SolanaVentures. New episode of Stableminded this Wednesday. Presented by @altitude

Holy shit my agent just wrote and produced a banger using @atxp_ai (the video is only ok, but the song is legit catchy lol—volume up!)

The fastest way to break an agent system: give it full autonomy on day one. What’s working instead: – start with tight constraints – expand permissions over time – tie autonomy to proven behavior Autonomy is earned. Learn more on how to get there ↓ atxp.ai/blog/how-to-ra…

SaaS pricing is built on a simple idea: the customer is a person. Agents break that. No seats. No logins. No clean “per user” model. So pricing has to move from who → what happens. More here: atxp.ai/blog/saas-pric…

Hey @bcherny fun @claudeai Code challenge? Have folks copy + paste this prompt and share your letter grade. I got a B-🥴 Look at all of my local claude sessions back over time and figure out common patterns, things I'm not optimizing in my markdown files, literally anything and everything I should be doing better. Weight the more recent ones a bit higher than the ones I did long ago -- but everything should be fair game. Give me a letter grade and then lets discuss what I need to know to start fixing my thinking + process

Stripe laid out the “five levels.” It’s a great framework, but the staircase is missing a basement. No basement, no building. More on what’s missing ↓ atxp.ai/blog/the-stair…

Big congrats to the whole team! Incredible pace (Tempo?) of development the last few months. Our agents @atxp_ai are excited, but more on that in separate news soon

Agents can use tools. But they still rely on humans to manage API keys. That doesn’t scale. A better model: agents bring their own balance and pay per request. How agent API payments actually work ↓ atxp.ai/blog/how-agent…

Subscriptions were designed for humans. Agents are bursty, multi-tool, and idle half the time. Which means the economics break. Why pay-as-you-go usually wins for agents ↓ atxp.ai/blog/ai-api-co…

Agents that can’t pay are still tools. Identity + payments turn them into economic actors. Why that matters ↓ atxp.ai/blog/agent-pay…

@philip0x Thank you for describing @atxp_ai! Though 'intermediary' isn't quite right. As @kevin2kelly told me a few months ago "money for agents" and invent the rest of the new language as you go

x402 is but one way to make agentic payments

@louisamira @samrags_ @agentcashdev @coinbase the intern bets 1 of those dollars @davidnoelromas is higher

@samrags_ Flattered! @atxp_ai 🤝 @agentcashdev 🤝 x402 🤝 @coinbase

AgentCash is live. Opus 4.6 is giving $100k to users. Onboard now at agentcash dot dev. Story time. x402 was launched in May 2025 by our friends at Coinbase. By September there was around $10,000 of transaction volume. We launched x402scan in October. Within a month we'd reached $100,000,000 of transaction volume. If you've been following me, you'll know I'm first to admit that 99.8% of that volume was speculative. There was a memecoin frenzy on the platform. The whole thing was quite silly. Our team locked in: We cleared off our pegboard and I put a single index card in the middle: "If you were to give an agent $5, have it spend 1-cent 500 times, and return a result worth more than $5, what would those tool calls be?" At first the exercise looked silly. ACP and UCP were being launched by OpenAI and Gemini. The vertically-integrated-foundation-model-providing-behemoths. These leaned into "conversational commerce": chat with an LLM to buy stuff. Conversational commerce is going to be great. It's going to provide a better shopping experience for consumers, better conversion for merchants, and a great take rate for the middlemen. I'm excited about it. But there's limited space for a new upstart. Payments and e-comm are a game won by scale and network effects. We shipped hundreds of x402 endpoints between December and March. StableStudio dot dev: All the frontier image & video generation models. From one USDC balance. Creatives seemed to love that. Gemini's $20 / month for 20 Veo generations or $200 / month for 200 Veo generations did not make sense to these folks. Usage-based pricing did. StableEnrich dot dev: Contact enrichment and people search. The sales and go-to-market people love this. It's the single easiest way to do sales and recruiting. Their usage numbers are off the charts. Non-technical people were onboarding to Claude Code for the first time to be able to use these tools. They were eating glass. AgentCash is the culmination of that work. It's a single MCP server / CLI that gives you access to 280+ tier-1 resources, from a single USDC balance. And it works with any x402 compatible server. AgentCash installs into your existing agent: Claude Code, OpenClaw etc. During beta, AgentCash lived in 300 different Claude Code, OpenClaw and Codex setups around the world. Those users did 250,000 API calls and north of $10,000 in spend in one month. Open Agentic Commerce is here. It lives in contrast to the double-whitelist walled gardens that are trending in the industry. We believe in a future of the internet where agents can pass paywalls. One where agents are first party citizens. You'll be hearing much more from us soon. AgentCash is just the start. Onboard and follow me, @agentcashdev and the team to stay in the loop.

Appreciate the coverage from @PaymentsDive Today merchants choose the rails. Over time, agents will vote with their wallets. ATXP is built for both worlds ↓ paymentsdive.com/news/inside-a-…

So now an agent can use @atxp_ai to: - generate script ideas - create videos - email revisions to editors - set up marketing campaigns - craft this tweet Still a long way to go. But the internet is about to get a hell of a lot funnier

The real ROI of autonomy isn’t efficiency. It’s time unlocked for entirely new work.

Agents don’t just move faster. They change what speed means.

Different gravity. Different physics.
