For your convenience, you can specify your LTX Studio configuration values under your LTX Studio account. If you specify multiple LTX Studio accounts, the API will automatically perform load balancing by randomly selecting an account with available capacity before making calls to LTX Studio.

This endpoint creates or updates an API account configuration for LTX Studio.

https://api.useapi.net/v1/ltxstudio/accounts

Request Headers 
Authorization: Bearer {API token}
Content-Type: application/json
# Alternatively you can use multipart/form-data
# Content-Type: multipart/form-data
Request Body 
{
  "cookie": "lt_id=user123; lt_token=eyJ...; lt_refresh_token=abc123...",
  "maxJobs": 20,
}
  • cookie is required, specify LTX Studio authentication cookies, see Setup LTX Studio for details.
  • maxJobs is optional, and sets the maximum number of concurrent jobs. Currently, LTX Studio does not appear to have a limit on the number of concurrent generations, instead they noticeably slow down concurrent generations past ~10. Feel free to set this to higher values if needed.
    Supported values: 1…100, default is 20.
