Show HN: Opencommerce – OpenRouter for commerce, one API for AI agents to buy

from the show-hn dept.

If you're building an AI agent that buys things for its users, opencommerce by Agentcard gives it one buy tool: search, cart, checkout and order tracking across 5,000+ online stores, through a single endpoint. No merchant integrations to build and no agent browser to run. Agentcard places the order once the user approves.

It's fast: it searches catalogues and makes a purchase in under 20 seconds.

We test the purchase flow at each monitored store, from search to checkout, and the results are public: https://opencommerce.sh/?utm_source=hn&utm_medium=community&...

Hi HN, I'm Karen, founder and CEO of Agentcard.

The quickest way to see it is our demo agent, which buys from the same stores. No sign-up: https://chat.opencommerce.sh/?utm_source=hn&utm_medium=commu...

Open for questions and feedback!

I just gave Agentcard a try. Cool concept! In my opinion having a generic agent that can purchase anything is difficult, as some purchases require more thinking and tooling than others. For example, I found purchasing a ticket with Agentcard a bit difficult, since the UI is not customized (nor dynamically adjusts) to flight tickets. Without a custom UI, comparing layovers, fees and departure/arrival is times complicated.
