  "url": "<your_mp3_url>"
}' "https://tosilk.zeabur.app/v1/decoder"

encoder

curl -X POST -H "Content-Type: application/json" -d '{
  "base64": "<your_mp3_base64>",
  "url": "<your_mp3_url>"
}' "https://tosilk.zeabur.app/v1/encoder"

in wechaty

const payload = { "url": await textToSpeechUrl(prompt) } // or payload = {"base64":"..."}
const api = await fetch('https://tosilk.zeabur.app/v1/encoder', {
  body: JSON.stringify(payload),
  method: 'post',
  headers: { "Content-Type": "application/json" }
})
const { data } = await api.json()

const sil = FileBox.fromBase64(data, `${new Date().getTime()}.sil`)
let voiceLength = Number(data.length / 1.8 / 1024 / 2).toFixed(0) * 1
if (voiceLength >= 60) {
  voiceLength = 59
}
voiceLength = voiceLength * 1000
sil.metadata = {
  voiceLength
};

await contact.say(sil)
