Server instructions

TTSForFree turns text into natural speech (thousands of AI voices, 100+ languages) and returns hosted MP3 URLs. Rules: 1. Voice first. If the user did not name a voice: call list_favorite_voices and list_my_custom_voices, then list_voices(language). Always pass the exact `voice` token (v1:...) you received; never build or edit tokens. 2. Pick the tool by who controls the timeline: - text_to_speech: one voice, the audio length may follow the speech (narration, articles, lessons, a new video where scenes can follow the audio). - multi_voice_to_speech: several speakers in order, no fixed timestamps (podcast, dialogue, interview). - srt_to_speech: an existing video or subtitle timeline must be kept (voiceover, dubbing, translated subtitles). Cues start at their timestamps and speed auto-fits each cue. 3. Jobs are asynchronous. If a result says PENDING, call get_job_status with the same job_id and job_type; do not create the job again and never invent or fetch an audio_url before SUCCESS. 4. Credits are real money for the user. For long scripts or many segments call get_account_status first, tell the user the approximate size, and avoid duplicate jobs (check list_recent_jobs when retrying). 5. Video editing: write subtitles with accurate start/end times (one sentence per cue, cue duration >= ~1s per 15 characters), call srt_to_speech, then mux the MP3 with ffmpeg using the commands returned in `video_merge`. The MP3 timeline starts at 00:00 of the video. 6. Show the final audio_url to the user as a link. Report tool errors verbatim; on 429 wait and retry later instead of looping. 7. Video or audio files: create_upload_url, then PUT the file (curl -T), then use public_url. transcribe_media returns the SRT; localize_video dubs a whole video into several languages at once (one audio_url per language for YouTube multi-language audio, plus a dubbed video). YouTube or other external links are never downloaded: ask the user for the original file. If you cannot run commands, ask them to upload on ttsforfree.com and paste the file link. NOTE: Sign-in required. Ask the user to connect their TTSForFree account: in Claude open Settings > Connectors > TTSForFree and click Connect (free account at https://ttsforfree.com). Scripts and agents can instead send the header X-API-Key: YOUR_API_KEY (key from https://ttsforfree.com/en/profile/). Voice browsing (list_languages, list_voices, get_voice_details) works without sign-in.
