Mureka API v1 has been updated with model improvements and increased character limits:

• For instrumental generation, older models (O1, V6, V5.5) now redirect to V7, we will be removing retired models on September 1, 2025.

Examples

Runway API v1 has been updated to support Gen-4 Aleph (video-to-video transformation) with the new POST gen4/video endpoint for video-to-video generation using text prompts and optional image conditioning.

Example

• 512p-6sec option (image-to-video only, fileID is required)
• 512p-10sec option (image-to-video only, fileID is required)

Example

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

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

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

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.
