LTX Studio API v1 endpoint POST videos/veo-create updated: the veo3 model now supports an optional starting frame. Cost estimate updated to reflect current LTX pricing.

HeyGen API v1 endpoint POST tts/create updated: added support for voice engine selection with new engine parameter. Engine options are voice-specific and include: auto, aws, azure, elevenLabs, elevenLabsV3, fish, google, openai, openaiEmo, panda, starfish. Defaults to elevenLabs with fallback to voice's default engine. The elevenLabsV3 model supports audio tags for enhanced emotional context.

Example

Kling released a website update earlier today. We're working on aligning our API with the recent changes.

Example

Midjourney API v1 (legacy) will be fully retired on September 1st, 2025

Starting September 1st, 2025, the Midjourney API will require a configuration to be present in order to make calls. The v1 (legacy) calls, where you were able to call the API without creating a config and by passing discord and channel values with every call, will no longer be supported.

To see a list of the currently configured Midjourney accounts, please visit GET account/midjourney.

Post your Discord token to POST account/midjourney to create an API configuration for your Midjourney bot. Please note that the configuration will use your Midjourney Direct Messages channel. If you used your own server or channel and have multiple accounts, you will need to update your code to use the new channel(s). If you only have a single Midjourney account, there’s no need to pass the channel value when making API calls.

For your reference:
• Setup Midjourney.
• Account Management & Subscription.

If you have any questions or concerns please contact support@useapi.net.

PS
We have customers who joined in 2023 and early 2024 and still, according to our stats, use v1-style API calls.
We sent you email(s) with the notification above, so this is a duplicate, just in case you missed the email.

Mureka API v1 TTS/speech generation endpoints added:

• POST speech - generate speech from text with voice cloning and multi-speaker conversations

• GET speech - retrieve generated speech recordings

• DELETE speech - delete speech recordings

• GET speech/voices - list available voices including cloned ones

• POST speech/voice - clone voice from MP3 audio samples

• DELETE speech/voice - delete cloned voices

Example

MiniMax API POST videos/agent-create enhanced with real-time streaming response using Server-Sent Events (SSE) for live progress updates during video generation.

Examples.

HeyGen API v1 has been decommissioned, consider switching to Mureka API for TTS/speech generation instead.

MiniMax music and TTS endpoints have been deprecated and will be removed, consider switching to Mureka API for speech/music generation.

LTX Studio API v1 endpoint POST videos/veo-create updated to support the Start Frame for the veo3-fast model and the resolution parameter for both veo3 and veo3-fast. You can now also use images generated via POST images/flux-create and POST images/flux-edit as references as well.

Example.

We updated MiniMax POST videos/create for the S2V-01 model with Subject Reference, and POST images/create to align with the subject/character validation logic released today by MiniMax on their website.
If you had jobs fail earlier today related to the above, you can safely rerun them.

MiniMax API v1 endpoint POST videos/create updated to support the End Frame parameter end_frame_fileID.

Example.

For the last four weeks, we have been notifying via email users who were still using the Midjourney API without setting up configuration accounts (aka Midjourney API v1, circa 2023).
According to our stats, there are a dozen active users who are still using the old way of calling the API and have ignored the warning emails.
We will be removing this ability starting September 1, 2025, so if you ignored those emails, you will be getting HTTP response 402:

{
  "error": "Configuration for channel <channel> not found. Please create a Midjourney API account at https://useapi.net/docs/api-v2/post-account-midjourney",
  "code": 402
}

You can follow the detailed instructions in the link provided in those emails.
In case you missed it: https://useapi.net/announcement-250808
It takes about 10–15 minutes to add configuration and update code so it no longer sends discord token with every call.
Please feel free to ask if you have any questions or concerns.

Midjourney API v2 has been updated:
• Upscaled image URLs are now available in the imageUx array. There is no longer a need to execute POST jobs/seed_async to retrieve upscaled images.
• When using --video upscaled video URLs are now available the videoUx array.
See both videoUx and imageUx in GET jobs/<jobid>.
• Prompt length for POST jobs/imagine has been extended from 2048 to 5000 characters.

⚠️ Security consideration when using videoUx and imageUx URLs:
URLs in both arrays follow this format: https://cdn.midjourney.com/<GUID>/…. They contain a job GUID which can be traced back to your account and will expose your account details such as your Discord account name and email. Exercise caution when posting these URLs publicly. You may want to save the URL content locally and serve it from your own origin, or proxy the links to obfuscate the original URLs.
