Not to take the bait on this bit of content marketing ("the future of agents is OAuth, says company that sells OAuth solution"), but: I disagree with the premise that agents should basically use the same APIs and auth mechanisms that humans & apps currently use.<p>I realize there's a strong impulse to not "reinvent the wheel," but what we have currently is unsustainable. Specifically, the fact that every API uses a slightly different REST API and its own unique authentication & authorization workflow. It worked fine for the days when application developers would spend a few weeks on each new integration, but it totally breaks down when you want to be able to orchestrate an agent across many user-defined services.<p>I think a simple protocol based on JSON and bog-standard public key encryption could allow agents to coordinate and spend credits/money based on human-defined budgets.
