List Agent Voices
Authentication
Enter your API key with the Bearer prefix, e.g. ‘Bearer sk_…’.
Response
Voice slug. Passed verbatim as voice_id on agent writes.
Voice provenance. Always shared on this endpoint — personal
/ cloned voices are not exposed here; they stay on
GET /v1/voices.
Speaker gender as classified by VMS. notSpecified is used
when the source dataset didn’t carry the metadata; the
console treats it as a neutral display label rather than a
filter gap.
Default locale for the voice (BCP-47-ish, e.g. en-US).
Preferred preview clip URL, locale-matched when possible.
Avatar URL for the picker UI. Null when no avatar is
configured; the wire is intentionally null rather than
"" so the picker doesn’t render a broken <img src="">.
