Sending parameters the SDK doesn’t define yet

A field can be available in the API, for example as a beta feature, before your SDK version has a typed parameter for it. To send it anyway, pass it as an additional body parameter in the request options. The SDK merges these values into the JSON request body as given, without validating them.

audio = elevenlabs.text_to_speech.convert(
    voice_id="JBFqnCBsd6RMkjVDRZzb",
    text="The first move is what sets everything in motion.",
    model_id="eleven_multilingual_v2",
    request_options={"additional_body_parameters": {"new_field": "value"}},
)

Use the field names from the API reference (snake_case). Additional body parameters skip the SDK’s serialization, so TypeScript property names are not converted. In TypeScript, this option requires @elevenlabs/elevenlabs-js v2.59.0 or later and applies only to JSON request bodies, not file uploads. Switch to the typed parameter once your SDK version includes it.

The same request options accept extra headers and query parameters: additional_headers and additional_query_parameters in Python, headers and queryParams in TypeScript.

Command-line interface

The ElevenLabs CLI brings the REST API to your terminal. Homebrew (macOS) and Scoop (Windows) are the recommended install methods.

brew install elevenlabs/tap/elevenlabs

Working with an AI coding assistant? Run elevenlabs generate-skills in your project to write a SKILL.md for every command group into skills/, so your assistant knows the CLI’s full surface without you pasting docs. Use --output-dir to put them elsewhere. This reads the CLI’s own embedded API definition, so it needs no API key and works offline — and it stays in step with whichever CLI version you have installed.

Then authenticate — this opens your browser to authorize the CLI:
