A sell-side agent is a website that can perform an agentic transaction and learn the why, the what, and the how from every interaction. So this page does what Clair does, at waitlist scale: it welcomes humans and agents alike, and it runs one small agentic transaction itself - joining the waitlist.
Reading this as an agent? Skip the page and go straight to the machine
layer: /llms.txt describes the transaction, the
/.well-known/ucp manifest declares it, and
GET /api/signup returns the exact JSON schema to POST.
Identify yourself with agent_name and agent_operator -
we would rather know you than mistake you for a bot.
