OpenKarta
An MIT-licensed open contract for agentic commerce — built by the community for the machine economy.
What we are
OpenKarta is an open standard that lets any AI agent discover a merchant, browse their catalogue, build a cart, get a signed quote, check out, and track an order — using exactly the same eight verbs across five item types: product, stay, flight, bus, service.
Small. Typed. Shippable. The v0.1 reference implementation lives in a single monorepo with a Node SDK, three reference agents, a conformance harness, and a consumer-side orchestrator. It is small enough that one engineer can read it in a weekend and ship a brand agent on Monday.
The contract should be open. The competition should be on service.
