# Kie.ai A unified API for developers building with video, image, music, and chat AI models. - Findings24: - ウェブサイト: - 料金: Freemium - カテゴリー: AIゲートウェイとルーティング, AI画像API, AI動画API ## Kie.aiとは？ Kie.ai is an API platform that gives developers access to video, image, music, and language models through one service. It brings models from multiple providers into a shared platform with a single credit wallet, helping teams add generation capabilities to applications and manage spending across different media types. The catalog includes models from Google, OpenAI, Anthropic, Kling, and other providers. Developers can choose models and output settings according to their workflow, with usage prices listed by model, modality, and configuration. ## Kie.aiでできること ### Multiple model categories Access chat, image, video, and music models through one API platform. The pricing catalog separates these categories and lists individual model configurations. ### Flexible video inputs Supported video models offer text-to-video, image-to-video, and reference-to-video generation. These inputs let applications create clips from written instructions or existing visual assets. ### Video output controls The Veo generation interface offers aspect ratios of 16:9 and 9:16, durations of 4, 6, or 8 seconds, and resolution options including 720p, 1080p, and 4K. Available combinations depend on the selected model. ### Generated video audio Veo supports synchronized audio, including dialogue and ambient effects. The generation interface identifies audio as experimental and warns that some videos may have no audio. ### Shared usage billing A credit wallet covers model usage without a subscription or monthly platform fee. Prices use units such as generated images, video seconds, and input or output tokens; Kie.ai states that failed generations are not charged. ## 利用シーン ### Build applications with multiple media types Developers can combine chat responses, generated images, video clips, and music within an application while managing model spending through one wallet. ### Produce social and campaign videos Content teams can turn prompts or existing images into short clips and choose portrait or landscape formats for social posts and marketing campaigns. ### Create and revise product imagery Design and commerce workflows can use the image generation and editing models to produce product visuals and refine existing images. ### Prototype visual storytelling Creators can test scenes from text or reference images, exploring motion and audio before committing to a broader production workflow. ## よくある質問 ### How is usage priced? Kie.ai uses pay-as-you-go credits with model-specific rates. For example, the pricing page lists Gemini 3.1 Pro input at $0.50 per million tokens and output at $3.50 per million tokens. Vidu Q4 image-to-video at 720p is listed at $0.076 per second. ### How do developers get started? Kie.ai provides API key access and API documentation. Its Veo page also includes a generation interface with prompt and output controls, plus JSON input and output panels for testing workflows. ### Can generated Veo videos be extended? The Veo interface includes an extension workflow that accepts a valid task ID from a previous generation and a prompt describing the continuation. It notes that videos generated at 1080p cannot be extended. ### What changes the cost of a video request? Rates vary by model and configuration. The pricing table distinguishes resolution, input method, native audio, and video input. Some models charge per second, while other listings quote a price per video. ## クイック情報 - **Product category**: AI API platform - **Primary users**: Developers and content creators - **Model modalities**: Chat, image, video, and music - **Support**: 24/7 support advertised - **Website**: https://kie.ai
