Japanese Text-to-Speech API: ja_JP Voice to MP3
A Japanese text-to-speech API returns an MP3 URL as JSON. On Woord that is POST /api/convert with Bearer auth and form fields (not JSON): text, gender_voice, language=ja_JP.
Starter is $9.99/mo. Trial is 8 days / 20k characters. Free cannot call convert. 10k characters per file. No MCP.
