Agent Commerce
OSP
Cresva's open specification for what an AI agent may do on a merchant's store. A storefront publishes a discovery document at /.well-known/osp.json declaring its endpoints and capabilities, and the protocol covers discovery, product query, price negotiation and transaction. Distinct from the Agentic Commerce Protocol, also abbreviated ACP, which is a different specification from OpenAI and Stripe. Published draft at v3.0, MIT licensed.
Why it matters
It is a control surface rather than a distribution channel. Platforms already syndicate catalogues to assistants; what none of them carries is the merchant's own terms, so an agent infers a price from a page and nothing tells it about your floor, your caps or what needs approval. OSP is where a merchant states those, and where what each agent channel actually bought comes back.
In practice
The document is served by the platform rather than hand-authored. A storefront that published before the rename keeps serving /.well-known/acp.json at the same time, because a well-known path is fetched by address and an agent that discovered you earlier has no way to learn a new one.
