# Compliance Call Recorder + AI Auditor

Compliance Call Recorder + AI Auditor — auto-record, batch-process with AI, flag violations, create tickets.

## Telnyx APIs Used

- **AI Inference**: `POST /v2/ai/chat/completions` — [API reference](https://developers.telnyx.com/api/inference/chat-completions)
- **Cloud Storage (S3-compatible)**: recordings are uploaded with the AWS S3 SDK (`boto3`) against the regional endpoint `https://{region}.telnyxcloudstorage.com`. Authentication is S3 SigV4 with your Telnyx API key supplied as **both** the access key and the secret key. See the [Cloud Storage quickstart](https://developers.telnyx.com/docs/cloud-storage/quick-start).

## Telnyx Webhook Events

This app handles these webhook events ([Call Control docs](https://developers.telnyx.com/docs/api/v2/call-control)):

- `call.answered` — Call connected — app begins interaction
- `call.hangup` — Call ended — app cleans up session, triggers post-call processing
- `call.initiated` — New inbound or outbound call detected
- `call.recording.saved` — Call recording saved — URL available for download/processing
- `call.transcription` — Real-time transcription chunk received
