 A Python CLI tool that downloads X (Twitter) Space recordings and renders an MP4 replay with audio and a compact participant view.

 ### Install the tool
 
 ```bash

 Cookies are also used to fetch the Space title, host, speakers, avatars, and replay chat timeline from X/Periscope metadata.
 
+### Environment variables
+
+Fetching metadata (required for the default video mode) needs a bearer token for X's web GraphQL API:
+
+```bash
+export X_BEARER_TOKEN="<token>"
+```
+
+Get this value from your own browser: open x.com while logged in, open DevTools → Network, and copy the `authorization: Bearer ...` header from any request to `x.com/i/api/graphql`. This is the public token issued to X's web client, not a personal secret, but it's not bundled with this tool — you provide your own.
+
+`X_AUDIO_SPACE_QUERY_ID` can optionally override the GraphQL query ID used for `AudioSpaceById` if X changes it.
+
 ### Speaker timeline
 
 With cookies, the tool automatically calls the replay `history` endpoint and builds participant/speaker timing from Space microphone events. If you already have speaker intervals from another extractor, you can override that with JSON:
