Day Pass

A 24-hour pass for Chan TTS and image materials — clear limits, queue OK, preview before download. V1 is short voiceover + image materials (not a finished text poster). This page is a demo of the flow, not fulfillment.

Claim your pass

After payment you get an email link (valid 7 days). Same purchase = one entitlement.

Demo entitlement: loading…

Fixture claim token:

Deep-link shape: /pass/claim?token=… (preview host; gateway validates claim_token).

Activate

Starts the 24-hour window only after a server eligibility / admit check (can we serve your pass right now). This is not “GET /health returned 200”.

This demo calls isolated /api/fixture/* (claim · activate · jobs · download stubs). Not production orders. localStorage is UI draft only — entitlement truth comes from the fixture server.

Workbench flow

Input → progress → preview → download. Refresh may keep the demo job on screen for UX. Live apps always re-validate entitlement and job status on the server.

TTS job sends voice_id only. Name is not auth.

Job: idle
Preview slot (demo — not real audio/image).

Downloads kept until — (demo)

Retention window: max(entitlement end, job complete) + 24h grace.

Custom voices (preview) not production · VOICE_ISOLATION off

Alpha UI against Beta PREPARE shapes. Calls isolated fixture /api/fixture/voices* (mirrors /v1/voices* (PREPARE)). Production flag stays unset — do not claim live custom voices. File picker upload only (multipart bytes). No URL/path fields. No forged owner headers.
