How to call ElevenLabs Multilingual v2

Pass elevenlabs/multilingual-v2 as the model field. The first request returns a 402 with the exact price; a signed retry runs it, and the client libraries fold the two into one call — how the payment works. Request and response shapes are in the docs.

curl -X POST https://blockrun.ai/api/v1/audio/speech \
  -H "Content-Type: application/json" \
  -d '{"model": "elevenlabs/multilingual-v2", "input": "Your order has shipped and arrives on Friday."}'

ElevenLabs Multilingual v2 or another speech model

Every speech model here takes the same request on the same endpoint, so trying another is a one-line change to the model field. The Text to Speech API page lists all of them side by side.
