Notte officially integrates with @agentcardhq 🤝

your agent can check out at real stores without ever seeing your card. it fills the checkout with a placeholder, you approve with your passkey, and your real card pays from your device

Let's go make some magic ✨ 🪄

[mrs. robot @keyserfaty]

we are happy to share that we raised $8m from Peak XV, Fin Capital, Robinhood and some amazing angels.

when we started @agentcardhq we asked ourselves a question: are people willing to buy things with agents? not so many months later Instinct happened, Muse happened and what we thought was going to take years was taking place now.

agents buying things on behalf of humans is still an unsolved problem. using users’ cards is one part of it but making the purchase itself is another big one (we announced https://t.co/qLbYqziMtG last week in an attempt to help solve this problem).

some months later we are still very much obsessed with this problem and with helping build this future for the next generations. it's a true privilege to work every day on problems with no simple solutions and to try to create clean and beautiful interfaces so that more companies can bring agents to every person on earth.

thanks to our investors for trusting us and to all of you for following this crazy ride. more cool things to come :)

Companies spent years battling bots. Now they’re fighting for their business.

AI agents are the majority of Web traffic and generate most code pushed to production. Soon, they'll be buying most of what gets sold online.

Can't wait to try Tug 🚢

[Ken Kocienda @kocienda]

For the past 9 months, I’ve been making Tug, an app to create a great user experience for AI coding. I made a video to introduce it.

Tug is for macOS, uses your Claude Code account, and is open source.

Now in beta! Let me know what you think!

amazon blocked @bot from shopping on its platform. @instinct still takes more than 15 minutes just to add products to your cart.

that’s why we’re bringing https://t.co/gHBaxQqMSn by @agentcardhq to iMessage via @onkeiki

you can add this to your existing imessage agent, and push it to production securely without rewiring your agent infra.

add shopping across 5000+ shops, payments.

customers text what they need. your agent finds it, builds a cart, and places the order after they approve.

[mrs. robot @keyserfaty]
