Vendor: https://kie.ai

## Tools available

**35** tools available. First 12:

- `KIEAI_ADD_INSTRUMENTAL` — Add Instrumental to Vocal Track — Add AI-generated instrumental accompaniment to an existing vocal track. Use when you need to generate instrumental music to accompany a vocal recording, allowing customization of style, mood, and creative parameters. The task completion will be notified via the callback URL.
- `KIEAI_ADD_VOCALS` — Add vocals to instrumental — Add AI-generated vocals to an existing instrumental music track. Use this action when you want to add singing or vocal tracks to accompany an existing instrumental audio file. The action submits a vocal generation task and returns a task ID that can be used to track the generation status. This action is asynchronous - use the returned taskId to poll for completion via the callback URL or check task status separately.
- `KIEAI_CREATE_MARKET_TASK` — Create Market Task — Create a task for unified model access through the Market API. Submit tasks to any supported AI model (Kling, Sora2, Hailuo, Wan, Google, Ideogram, ElevenLabs, etc.) through a single unified interface. Specify the model and its input parameters, then receive a task ID to poll for completion. Use this action when you need to generate content (text-to-speech, images, video, etc.) via Kie.ai's unified Market API with access to multiple AI providers through one endpoint.
- `KIEAI_CREATE_MUSIC_VIDEO` — Create music video from generated audio — Create a music video (MP4) combining generated music with visuals. Use this action when you need to generate an MP4 music video from previously generated music tracks. The action requires a task ID from the music generation process and an audio ID for the specific track. The video generation is async - results are delivered to the specified callback URL. Once the video is ready, the callback URL receives a POST request with: - code: 0 for success, 500 for error - data.task_id: The unique task identifier - data.video_url: The video URL (valid for 14 days)
- `KIEAI_EXECUTE_GPT_CODEX` — Execute GPT Codex — Access GPT Codex capabilities through the KIE.AI Market API. Use when you need to leverage advanced code understanding and generation abilities via the Codex model for tasks such as code completion, refactoring, bug explanation, or general programming assistance. The action supports both single-turn queries (plain string input) and multi-turn conversations (list of message objects with roles). Optional features include configurable reasoning depth, web search for up-to-date information, and function calling for structured tool use. Note: Web search and function tools are mutually exclusive and cannot be used together in the same request. When streaming is enabled (stream=True), the response is delivered incrementally via SSE events.
- `KIEAI_EXTEND_MUSIC` — Extend Suno Music — Extend an existing Suno music track with additional AI-generated content. Use this action when you need to extend or modify existing music by creating a continuation or variation based on the provided audio ID and parameters. The action submits a generation request and returns a task ID that can be used to track the progress via callback. Note: When defaultParamFlag is false, provide custom parameters (prompt, styleWeight, etc.) to control the extension behavior. When defaultParamFlag is true, provide continueAt, style, and title instead.
- `KIEAI_EXTEND_VEO_VIDEO` — Extend Veo Video — Extend an existing Veo3.1 video with additional AI-generated content. Continues a previously generated video by adding new frames that seamlessly follow the original video. Use this action when you need to extend a video generated through the Veo3.1 API with additional content. After submission, poll 'Get Veo Video Details' using the returned taskId to check extension status until completion. Note: Video extension is asynchronous. You will receive a taskId in the response that must be used to poll for completion status. Only videos generated through the Veo3.1 API can be extended, and videos generated after 1080P cannot be extended.
- `KIEAI_GENERATE_ALEPH_VIDEO` — Generate Aleph Video — Generate AI video using Runway Aleph model from text prompts. Creates high-quality video content based on detailed text descriptions, optionally with reference video or image inputs. Use when you need to generate a video from a text description (text-to-video) or transform an existing video with AI (video-to-video). After submission, poll 'Get Aleph Video Details' using the returned taskId to check generation status until completion. Note: Video generation is asynchronous. You will receive a taskId in the response that must be used to poll for completion status. Generated videos are available for 14 days after completion.
- `KIEAI_GENERATE_COVER` — Generate Music Cover — Generate a personalized cover version of a song using AI. Use when you want to create AI-generated variations or custom covers of existing music tracks. Each music task can only generate one Cover. Cover images are typically valid for 14 days. The action returns a task ID that can be used to track the generation progress. The callback URL will receive a POST request when cover generation completes, containing the task ID and generated image URLs.
- `KIEAI_GENERATE_FLUX_KONTEXT_IMAGE` — Generate Flux Kontext Image — Generate or edit images using the Flux Kontext model. Supports both text-to-image generation and image editing modes. Use when you need to create new images from text descriptions or edit existing images with AI-powered transformations. The API returns a task ID that can be used to poll for completion status. Generated images expire after 14 days.
- `KIEAI_GENERATE_GPT4O_IMAGE` — Generate GPT-4o Image — Generate images using the GPT-4o image generation model. Creates AI-generated images from text prompts. Use when you need to create new images from text descriptions. The API returns a task ID that should be polled using the 'Get GPT-4o Image Details' action to check completion status and retrieve the generated image URLs. Generated images are stored for 14 days and download URLs are valid for 20 minutes.
- `KIEAI_GENERATE_LYRICS` — Generate AI Lyrics — Generate creative lyrics using AI. Creates new song lyrics based on the provided prompt, style, and other parameters. Use when you want to create AI-generated song lyrics for a music track or need creative lyrical content. The action returns a task ID that can be used to track the generation progress. When generation completes, the callback URL will receive a POST request with the generated lyrics data including 2-3 lyric variations with titles. Note: Generated lyrics are retained for 14 days.

## How agents use Kieai

Inside a Definable workflow, Kieai is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Kieai** — the Researcher (GPT-5.5) pulls context from Kieai (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Kieai** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Kieai (create record, post message, draft email).
- **Designer / Engineer → Distributor → Kieai** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Kieai (attach file, open PR comment, post status).

The Verifier checks every Kieai call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
