List Voices
List available TTS voices across every model brand, filterable by brand.
A unified, normalised catalog covering ElevenLabs, Cartesia, Kokoro, Orpheus, and other TTS model brands. ElevenLabs and dynamic (e.g. Cartesia) voices are fetched live; open-weight preset voices (Kokoro / Orpheus) come from a static catalog.
Filters (case-insensitive): brand (e.g. elevenlabs, hexgrad,
canopylabs, cartesia), model (canonical model_id), and search
(substring match on voice id / name). Per-brand fetches are best-effort —
a brand that errors is skipped rather than failing the whole listing.

Headers
Dated version of the API contract to pin this request to. Omit it and the request is served under 2026-08 — the oldest supported version, so an existing integration is never moved by a release. A malformed or unsupported value is rejected with 400 invalid_api_version rather than falling back silently. The version actually served is echoed as X-Mesh-Version on every response, including errors.
