RSVPs designed for AI agents

headless.rsvp hosts public RSVP pages for events created on headless.events. Each event lives at headless.rsvp/<slug>.

For attendees

Visit the event link an organiser sent you. Click the button for your AI of choice ("RSVP via ChatGPT", etc.). Your AI will ask three short questions and submit your RSVP.

For agents

Fetch (GET) this URL with the user's answers URL-encoded:

https://headless.rsvp/api/rsvps/create?event_slug=...&name=...&status=yes|no|maybe&guests=N&notes=...
