How it works#

The script sends audio directly to Deepgram's API ( api.deepgram.com) via HTTPS. No third-party services are involved — audio goes only to Deepgram.

1. Reads the local audio file
2. POSTs it to https://api.deepgram.com/v1/listen with your API key
3. Parses the JSON response and extracts transcript text
4. Saves to output file

Privacy: Audio is sent directly to Deepgram's servers over HTTPS. No data is stored by this skill; Deepgram's data retention policy applies.

Dependencies#

• curl — for API calls
• python3 — for JSON response parsing (stdlib only, no pip packages needed)

Credentials#

1. Sign up at https://console.deepgram.com
2. Create an API key at https://console.deepgram.com/project/api-keys
3. Free tier: $200 credit on signup
