What stream_chapter_snapshot_audio does on Elevenlabs
AI agents call stream_chapter_snapshot_audio to retrieve information from Elevenlabs without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
chapter_id | string | Yes | The ID of the chapter. |
project_id | string | Yes | The ID of the Studio project. |
output_path | string | — | Where to write the returned bytes. Relative paths resolve against ELEVENLABS_OUTPUT_DIR. Omit it to get the data inline as base64 (small files only). |
convert_to_mpeg | boolean | — | Whether to convert the audio to mpeg format. |
chapter_snapshot_id | string | Yes | The ID of the chapter snapshot. |
Parameters from the server's own tool schema.
Why stream_chapter_snapshot_audio is rated Low
Even though stream_chapter_snapshot_audio only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
