# Loom Transcript Fetcher Fetch the transcript from a Loom video using Loom's GraphQL API. ## Instructions Given the Loom URL: $ARGUMENTS ### 1. Extract the Video ID Parse the Loom URL to extract the 32-character hex video ID. Supported URL formats: - `https://www.loom.com/share/<video-id>` - `https://www.loom.com/embed/<video-id>` - `https://www.loom.com/share/<video-id>?sid=<session-id>` The video ID is the 32-character hex string after `/share/` or `/embed/`. ### 2. Fetch Video Metadata Use the `WebFetch` tool to POST to `https://www.loom.com/graphql` to get the video title and details. Use this curl command via Bash: ```bash curl -s 'https://www.loom.com/graphql' \ -H 'Content-Type: application/json' \ -H 'Accept: application/json' \ -H 'x-loom-request-source: loom_web_45a5bd4' \ -H 'apollographql-client-name: web' \ -H 'apollographql-client-version: 45a5bd4' \ -d '{ "operationName": "GetVideoSSR", "variables": {"id": "<VIDEO_ID>", "password": null}, "query": "query GetVideoSSR($id: ID!, $password: String) { getVideo(id: $id, password: $password) { ... on RegularUserVideo { id name description createdAt owner { display_name } } } }" }' ``` ### 3. Fetch the Transcript URLs Use curl via Bash to call the GraphQL API: ```bash curl -s 'https://www.loom.com/graphql' \ -H 'Content-Type: application/json' \ -H 'Accept: application/json' \ -H 'x-loom-request-source: loom_web_45a5bd4' \ -H 'apollographql-client-name: web' \ -H 'apollographql-client-version: 45a5bd4' \ -d '{ "operationName": "FetchVideoTranscript", "variables": {"videoId": "<VIDEO_ID>", "password": null}, "query": "query FetchVideoTranscript($videoId: ID!, $password: String) { fetchVideoTranscript(videoId: $videoId, password: $password) { ... on VideoTranscriptDetails { id video_id source_url captions_source_url } ... on GenericError { message } } }" }' ``` Replace `<VIDEO_ID>` with the actual video ID extracted in step 1. The response contains: - `source_url` — JSON transcript URL - `captions_source_url` — VTT (WebVTT) captions URL ### 4. Download and Parse the Transcript Fetch **both** URLs returned from step 3 (if available): 1. **VTT captions** (`captions_source_url`): Download with `curl -sL "<url>"`. This is a WebVTT file with timestamps and text. 2. **JSON transcript** (`source_url`): Download with `curl -sL "<url>"`. This is a JSON file with transcript segments. Prefer the VTT captions as the primary source since they include proper timestamps. Fall back to the JSON transcript if VTT is unavailable. ### 5. Present the Transcript Format and present the full transcript to the user: **Video:** [Title from metadata] **Author:** [Owner name] **Date:** [Created date] --- **0:00** - First transcript segment text... **0:14** - Second transcript segment text... (continue for all segments) --- ## Error Handling - If the GraphQL response contains a `GenericError`, report the error message to the user. - If both `source_url` and `captions_source_url` are null/missing, tell the user that no transcript is available for this video. - If the video URL is invalid or the ID cannot be extracted, ask the user for a valid Loom URL. ## Notes - No authentication or cookies are required — Loom's transcript API is publicly accessible. - Only English transcripts are available through this API. - Transcripts are auto-generated and may contain minor errors.
