No signup, no key. Run three real calls against the live demo tenant: mint a referral link, capture a signup, and read the attribution back. The JSON below is the actual response, never a mock.
Mint a shareable code for a freshly generated demo referrer.
Bind a new demo account to the code from step 1. This is the attribution.
List the referrer's attributions and see the signup you just captured.
The keyless sandbox above is the real API. With a key you get your own tenant, invites from warmed email infrastructure, and idempotent calls that never double-count. We are onboarding builders in a private beta.
