List the speech models available for POST speech/create, with each model’s provider, character limit, credit formula, and the live list of supported_language_codes. This is the source of truth for which language_code values a model accepts — text length and language_code on a generation are validated against it.

For MiniMax models the response also carries the emotions enum (the values accepted by the emotion voice setting).

Only MiniMax (speech-2.8-hd, speech-2.8-turbo) models carry the emotions field — ElevenLabs models do not accept an emotion setting. eleven-v3 auto-detects the language and rejects language_code on a generation.

Model 
{   // TypeScript, all fields are optional
  default_model: string
  provider_groups: {
    provider: string
    models: {
      model: string
      display_name: string
      provider: string
      max_characters: number
      supported_language_codes: string[]
      credit_formula: {
        unit_characters: number
        unit_credits: number
        round_up: boolean
      }
      // present on MiniMax models only
      emotions: string[]
    }[]
  }[]
}

  • curl "https://api.useapi.net/v2/pixverse/speech/models" \
   -H "Accept: application/json" \
   -H "Authorization: Bearer …"

  • const token = "API token";

  headers: {
    "Authorization": `Bearer ${token}`,
  },
});
const result = await response.json();
console.log("response", {response, result});

  • import requests

headers = {
    "Content-Type": "application/json",
    "Authorization" : f"Bearer {token}"
