Claim a 4A audience invite
This page is one way to claim a 4A invite. The same 4a:// URL
works in the Sonata plugin and the 4a CLI — pick whatever you
trust.
Expected URL shape:
https://claim.4a4.ai/invite/<slug>/<epoch>?k=4ainv1…
Continue with GitHub to derive your 4A pubkey, then post the claim event.
What happens when I click "Continue with GitHub"?
We start an OAuth round trip with the 4A gateway at api.4a4.ai.
After auth we sign a kind:30522 claim event with the
invite key from this URL and publish it to the relay set. The audience
owner's daemon picks it up, rotates the audience key, and grants you a
per-epoch decryption key.
Your invite key never leaves this browser session. Note: the v0.5 first-pass implementation POSTs the invite key to the gateway over HTTPS so a Nostr signing library doesn't have to load in the page; a hardening pass will move signing into the page once the §5 walk-through proves out.
The audience owner should grant you a per-epoch key shortly. You can keep this page open or close it.
What kind of access do you want?
Run this from a terminal:
