EasyVoice text to speech

Enroll a custom cloned voice from an audio sample (async). Requires a Pro or active 7-day pass key. Provide exactly one of audio_base64 or audio_url (https). Sample limits: 10 MB max upload; wav, mp3 or m4a; a 10–30 second clean single-speaker recording (enrollment rejects clips shorter than 10 or longer than 30 seconds; trim longer recordings first). Account limits: maximum 3 cloned voices, 5 enrollments per day. Returns a voice_id with status "enrolling" — check list_voices until its status is "ready", then use it in create_podcast.

Create a two-host (A/B) podcast episode as an async job. Requires a Pro subscription key. Up to 60 segments; combined text up to 30,000 characters. voice_a and voice_b set the two speaker voices — your READY cloned voice_* ids are allowed. Returns a job id — poll get_job_status.

Generate long-form narration (up to 500,000 characters ≈ 9 hours of audio) as an async job. Requires a Pro subscription key. Kokoro narration voices only — Arabic (ar_*) and cloned (voice_*) voices are rejected by the Long-Form engine. Returns a job id — poll get_job_status; parts render progressively and audio_url appears when completed.

Check the status of a long-form, podcast or tts job owned by this key. Returns status plus audio URL(s) when completed. Audio links are not guaranteed to persist — download promptly.

Check this API key's plan and usage. Free keys see today's used/remaining characters (shared 5,000/day pool, resets at midnight UTC), the 20 requests/minute rate limit and 2-concurrent cap. Pro keys are unlimited (fair use: 10M characters per rolling 30 days, then slowed to 30 requests and 10,000 characters a minute, 10 and 3,000 past 20M, on every surface -- never blocked or billed) at 60 requests/minute.

List all 66 EasyVoice catalog voices (id, name, language, accent, gender, free/pro tier) plus this key's cloned voices. Call this before text_to_speech or create_podcast to pick voice ids.

Convert text to a downloadable MP3 or WAV audio file with one of EasyVoice's 66 neural voices. Returns a hosted audio URL (no inline audio). Per-call limit: 8,000 characters (4,000 for Arabic ar_* voices) — text over the limit is automatically queued as a background job instead of erroring; poll get_job_status with the returned job_id for the result. Free keys can use the 12 free voices; Pro ($9.99/mo) unlocks the full catalog. A Pro account past the fair-use line is paced in characters a minute: a call may wait up to 20 seconds, and one that would wait longer returns a tool error saying when to retry.
