Unifically AI API: Veo, Suno, Kling & 120+ AI Models

• Generate video — Generate a video from a text prompt (and optional start/end frames). Defaults to Google Veo 3.1 Fast, which includes native audio. Switch model with the model parameter (Veo, Kling, Hailuo/MiniMax, and more). The tool waits for the result and returns the video URL; pass callback_url for long jobs to return immediately.
• Generate image — Generate or edit an image from a text prompt. Defaults to Google Nano Banana Pro. Pass image_urls to edit or use reference images. Returns the image URL. (To upscale an existing image, use upscale_media instead.)
• Generate audio — Speech and sound: text-to-speech (default; optional voice_id, see list_resources), sound effects (model 'sfx', optional duration), multi-voice dialogue (model 'dialogue': pass the turns in the dialogue parameter, not prompt), transcription (model 'stt': pass audio_url, get text back; optional diarize/language_code), voice change (model 'voice-changer': audio_url + target voice_id) and audio cleanup (model 'voice-isolation': audio_url). Returns the audio URL (or the transcript for 'stt'). For mus
• Generate music — Full Suno suite. mode 'music' (default) makes a new song from a description (or lyrics with custom:true). Transform an existing track (pass audio_url): 'cover' (new style), 'extend' (longer, +continue_at), 'add-vocals' / 'add-instrumental' (layer on). Split a prior clip (pass clip_id): 'stems' / 'stems-all', or 'wav' to export it. 'lyrics' writes lyrics; 'sound' makes a sound effect from a prompt. Set instrumental for no vocals. Returns the audio URL(s).
• Edit video — Edit an existing video from a prompt, or transfer motion onto a subject image. Pass the source in video_url and the change in prompt. Defaults to Google Gemini Omni video edit; switch with model ('kling-edit', 'wan-edit', or 'motion-control' for Kling motion transfer with a subject image in image_urls). This is for changing an existing clip — to make a new video from scratch use generate_video, to extend one use extend_video, to upscale use upscale_media. Returns the video URL.
• Upscale media — Upscale an image or a video. Pass exactly one source: image_url (Topaz image upscale — any image; multiplier via upscale_factor, preset/face_enhancement via provider_options), video_url (Topaz video upscale — any video; target size via resolution; preset/target_fps/frame_interpolation via provider_options), or task_id with model 'veo-upscale' / 'grok-upscale' (model-internal upscalers that ONLY work on their own model's completed generations). For any media not generated by Veo/Grok, use the URL
• Extend video — Extend a previously generated video by its own model's extender (pass the task_id of the completed generation). Veo (default): requires prompt; aspect ratio is inherited. For a longer extension, try extending the extend-result's task_id again — chaining is not officially documented, so if it fails, regenerate at the target length instead. Grok: extends a Grok Imagine video — either preset mode (video_preset) or custom mode (prompt + extend_at + extend_duration). Extenders only work on their own
• Upload file — Get a public https URL for a file — the generation tools accept ONLY public https URLs, never local paths or inline data. FOR A LOCAL FILE: call this with the file's MIME type, e.g. { content_type: 'image/png' }. You get back an upload_url you can PUT the file to with plain curl and NO api key — full quality, zero tokens; CDN upload limits apply: curl -X PUT '<upload_url>' --data-binary @<path> The file_url comes back in the same response; pass it to the generation tool. Also takes { url } to
• Get task status — Get the status and (if completed) output URL of a task by id. Use to resume after a webhook, a polling timeout, or a generation started with wait:false. Pass wait:true to block until it finishes.
• List tasks — List the account's past generation tasks, newest first, with pagination. Filter by status (processing/completed/failed), model id, category (video/image/audio/text/llm), provider, or a created_after/created_before time window. Use it to find an earlier generation's task_id (for get_task, extend_video, or the veo/grok upscalers) or to review recent spend. Within one filter, comma-separated values are OR'd; different filters are AND'd.
• List resources — List a model provider's voices so you can pass the right id to a generation tool. Default 'elevenlabs-voices' (the voices for generate_audio); also covers Kling and Google Veo voices. Returns each voice's id and name. (This is Unifically's resource catalog; it is not the MCP protocol's resources/list.)
• List models — List the model catalog (video, image, audio, upscale) with the short aliases you can pass as 'model'. Filter by category and/or provider (e.g. provider: 'google'). Use the returned ids or aliases on the generation tools. Refreshed hourly from the live catalog.
• Preview cost — Estimate the cost of a task without creating it or charging the account. Pass the model and the full input payload.
• Check balance — Return the account's current balance in USD. Takes no parameters.
