What's shipped.

Stripe metered billing

Usage is now reported to Stripe in real time. Invoice at month-end based on exact seconds captured.

Dashboard billing tab

View current period usage, download invoices, and add or update payment methods from the dashboard.

No-double-billing guard

Unique constraint on (source_type, source_id) prevents any meeting or audio file from being billed twice, even on retries.

4-retry delivery with backoff

Failed webhook deliveries retry at 0s, 1m, 5m, 30m, and 2h automatically via BullMQ.

Delivery log in dashboard

Every webhook attempt is logged with status code, latency, and response body. Replay any event from the UI.

HMAC signature format

Signature header format is now t={unix},v1={hmac} matching the Stripe convention most teams already handle.

Idempotency on job restart

Worker restart no longer re-dispatches already-delivered webhooks.

Async STT for large files

Files over 25 MB are processed by a background BullMQ job. Poll GET /v1/transcriptions/:id for status.

Cloudflare R2 storage

All audio files are now stored in R2 with presigned access URLs (1hr expiry). Nothing is stored in /tmp.

POST /v1/audio/transcriptions

OpenAI-compatible endpoint for synchronous audio transcription up to 25 MB.

Speaker diarisation

Segments now include speaker_id and confidence scores from faster-whisper large-v3.

Meeting bot (Google Meet)

Send a bot to any Google Meet via POST /v1/bots. Vexa-backed, V1CE Notetaker persona.

Bot lifecycle webhooks

Events: bot.joining, bot.waiting, bot.joined, bot.failed, meeting.started, meeting.ended, meeting.completed.

API key authentication

Argon2id-hashed API keys. Live keys (gk_live_) and test keys (gk_test_) scoped per environment.

GET /v1/meetings/:id/transcript

Fetch the full diarised transcript from the database after meeting.completed fires.
