Prompt, duration, and aspect ratio on one endpoint. - **Image to Video** — Animate a still frame. Pass a reference image and a motion prompt for controlled camera moves. - **Video Editing** — Re-cut, restyle, or replace regions in an existing clip without re-rendering the whole shot. - **Video Upscale** — Take a 480p draft to 1080p or 4K once the edit is locked. Cheaper than generating at full resolution. - **Lip Sync** — Drive a talking head from an audio track. Works with generated or uploaded footage. - **AI Avatar** — Render a consistent presenter from a single reference image and a script. ## Video models on one key | Model | Provider | Price | | --- | --- | --- | | Seedance/seedance-2.0 | Bytedance | $0.27-$2.20 / second | | Kling/kling-3.0 | Kuaishou | $0.18-$0.91 / second | | Veo 3.1/veo-3.1 | Google | $2.50 / video | | Gemini Omni/gemini-omni-character | Google | Free / video | | Grok Imagine | xAI | $0.10-$0.30 / video | | Hailuo/hailuo-02-image-to-video-pro | MiniMax | $0.57 / video | | HappyHorse/happyhorse-1.0-i2v | Alibaba | $0.24-$0.41 / second | | InfiniteTalk/infinitetalk-from-audio | MeiGen-AI | $0.03-$0.12 / second | [View all 76 video models](https://runapi.ai/models?modality=video.md) ## Sign in to generate - **Seedance/seedance-2.0** — $0.27-$2.20 / second - **Kling/kling-3.0** — $0.18-$0.91 / second - **Veo 3.1/veo-3.1** — $2.50 / video Quickstart ## Create a video task POST /api/v1/gemini_omni/text_to_video #### curl ```bash curl https://runapi.ai/api/v1/gemini_omni/text_to_video \ -H "Authorization: Bearer $RUNAPI_API_KEY" \ -H "Content-Type: application/json" \ -d '{"model":"gemini-omni-flash-1-1","prompt":"A presenter walks through a bright studio.","duration_seconds":4}' ``` #### Python ```python import json import os import requests response = requests.post( "https://runapi.ai/api/v1/gemini_omni/text_to_video", headers={"Authorization": f"Bearer {os.environ['RUNAPI_API_KEY']}"}, json=json.loads("{\"model\":\"gemini-omni-flash-1-1\",\"prompt\":\"A presenter walks through a bright studio.\",\"duration_seconds\":4}") ) response.raise_for_status() print(response.json()) ``` #### Node.js ```javascript const response = await fetch("https://runapi.ai/api/v1/gemini_omni/text_to_video", { method: "POST", headers: { "Authorization": "Bearer " + process.env.RUNAPI_API_KEY, "Content-Type": "application/json" }, body: JSON.stringify({"model":"gemini-omni-flash-1-1","prompt":"A presenter walks through a bright studio.","duration_seconds":4}) }); console.log(await response.json()); ``` #### Go ```go package main import ( "io" "net/http" "os" "strings" ) func main() { payload := strings.NewReader("{\"model\":\"gemini-omni-flash-1-1\",\"prompt\":\"A presenter walks through a bright studio.\",\"duration_seconds\":4}") request, err := http.NewRequest("POST", "https://runapi.ai/api/v1/gemini_omni/text_to_video", payload) if err != nil { panic(err) } request.Header.Set("Authorization", "Bearer "+os.Getenv("RUNAPI_API_KEY")) request.Header.Set("Content-Type", "application/json") response, err := http.DefaultClient.Do(request) if err != nil { panic(err) } defer response.Body.Close() io.Copy(os.Stdout, response.Body) } ``` #### Response ```json { "id": "tsk_example", "status": "processing" } ``` ## Four Steps to Your First Generation **How it works** 1. **Get Your API Key** - Sign up and copy your key from the dashboard. 2. **Choose a Model** - Pick the model that fits your input and output needs. 3. **Send a Request** - POST to /api/v1/kling/text_to_video with your prompt, model, and parameters. 4. **Get Your Video** - Poll the task or use a webhook, then download your generated video. ## Why Developers Choose RunAPI - **One Key, All Models** - Stop juggling API keys.

Access Kling, Seedance, Veo, Runway, Hailuo, and more with one API key. Browse the model catalog for available versions, capabilities, and prices. ### Can I animate images, edit videos, or extend clips? Yes, with a model that supports the relevant endpoint. Image-to-video, video editing, extension, upscaling, and lip sync have different input requirements; check the selected model’s documentation. ### How is video billed? Rates and billing units vary by model and endpoint. Duration, resolution, and other options can affect the price. Check the catalog rate and request parameters before submitting a task. ### How do I receive the generated video? Video generation runs asynchronously. Submit a request, save the returned task ID, then poll the task endpoint or configure a webhook. The completed task contains the video result. ### Which durations and resolutions are supported? Supported durations, resolutions, and aspect ratios depend on the model and operation. Use the options listed in the endpoint documentation; settings shown in the playground are not available on every model. ### How do I start using the Video API? Sign in, create an API key, and choose a video model. Use the quickstart code or an SDK to submit a request, then retrieve the result by polling or webhook. ## Ship video generation this week One API key for video generation, editing, and extension. Choose a model, check its price, and start building. - [Get API Key](https://runapi.ai/login) - [Read the docs](https://runapi.ai/docs/guides) --- ## More from RunAPI - [Home](https://runapi.ai/.md) ### Product - [Model Catalog](https://runapi.ai/models.md) - [Pricing](https://runapi.ai/pricing.md) - [Providers](https://runapi.ai/models#all-models) ### Developers - [Documentation](https://runapi.ai/docs/guides) - [SDKs](https://runapi.ai/sdk.md) - [CLI](https://runapi.ai/cli.md) - [MCP Server](https://runapi.ai/mcp.md) ### Guides - [Claude Code vs Cursor](https://runapi.ai/claude-code-vs-cursor.md) - [Cursor API Setup](https://runapi.ai/cursor-api-setup.md) - [RunAPI vs OpenRouter](https://runapi.ai/openrouter-alternative.md) ### Company - [Enterprise](https://runapi.ai/contact.md) - [Contact](https://runapi.ai/contact.md) ### Legal - [Terms](https://runapi.ai/terms.md) - [Privacy](https://runapi.ai/privacy.md) - [Site index for agents](https://runapi.ai/llms.txt) Contact: contact@runapi.ai ## Structured data ```json [ { "@context": "https://schema.org", "inLanguage": "en", "@type": "WebSite", "name": "RunAPI", "url": "https://runapi.ai/", "potentialAction": { "@type": "SearchAction", "target": { "@type": "EntryPoint", "urlTemplate": "https://runapi.ai/models?q={search_term_string}" }, "query-input": "required name=search_term_string" } }, { "@context": "https://schema.org", "inLanguage": "en", "@type": "Organization", "name": "RunAPI", "url": "https://runapi.ai/", "logo": { "@type": "ImageObject", "url": "https://runapi.ai/icon.svg" }, "sameAs": [ "https://github.com/runapi-ai" ] }, { "@context": "https://schema.org", "inLanguage": "en", "@type": "SoftwareApplication", "name": "AI Video Generation API", "applicationCategory": "DeveloperApplication", "description": "Generate video with Kling, Seedance, Veo, Runway, and more through one video generation API.
