Supports custom resolutions up to 4096x4096 with enhanced typography for sharp text rendering in posters and logos. ## Authentication ```bash export WAVESPEED_API_KEY="your-api-key" ``` Get your API key at [wavespeed.ai/accesskey](https://wavespeed.ai/accesskey). ## Quick Start ### Text-to-Image ```javascript import wavespeed from 'wavespeed'; const output_url = (await wavespeed.run( "bytedance/seedream-v4.5", { prompt: "A minimalist coffee shop logo with clean typography" } ))["outputs"][0]; ``` ### Image Editing The `images` parameter accepts an array of image URLs (1-10 images). If you have local files, upload them first with `wavespeed.upload()` to get a URL. ```javascript import wavespeed from 'wavespeed'; // Upload a local image to get a URL const imageUrl = await wavespeed.upload("/path/to/photo.png"); const output_url = (await wavespeed.run( "bytedance/seedream-v4.5/edit", { images: [imageUrl], prompt: "Add warm sunset lighting and lens flare" } ))["outputs"][0]; ``` You can also pass existing image URLs directly: ```javascript const output_url = (await wavespeed.run( "bytedance/seedream-v4.5/edit", { images: ["https://example.com/photo.jpg"], prompt: "Add warm sunset lighting and lens flare" } ))["outputs"][0]; ``` ## API Endpoints ### Text-to-Image **Model ID:** `bytedance/seedream-v4.5` Generate images from text prompts with custom resolutions up to 4096x4096. #### Parameters | Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | `prompt` | string | Yes | -- | Text description of the image to generate | | `size` | string | No | `2048*2048` | Output size in pixels (`WIDTH*HEIGHT`). Each dimension: 1024-4096. | #### Example ```javascript import wavespeed from 'wavespeed'; const output_url = (await wavespeed.run( "bytedance/seedream-v4.5", { prompt: "A movie poster for a sci-fi thriller with bold title text 'HORIZON' at the top", size: "2048*3072" } ))["outputs"][0]; ``` ### Image Editing **Model ID:** `bytedance/seedream-v4.5/edit` Edit existing images using text prompts. Supports up to 10 input images. Preserves facial features, lighting, and color tone from input images. #### Parameters | Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | `images` | string[] | Yes | `[]` | URLs of input images to edit (1-10 images). Must be publicly accessible. | | `prompt` | string | Yes | -- | Text description of the desired edit | | `size` | string | No | -- | Output size in pixels (`WIDTH*HEIGHT`). Each dimension: 1024-4096. | #### Example ```javascript import wavespeed from 'wavespeed'; const imageUrl = await wavespeed.upload("/path/to/portrait.png"); const output_url = (await wavespeed.run( "bytedance/seedream-v4.5/edit", { images: [imageUrl], prompt: "Transform into a vibrant pop art style with bold colors", size: "2048*2048" } ))["outputs"][0]; ``` #### Multi-Image Editing ```javascript const img1 = await wavespeed.upload("/path/to/face.png"); const img2 = await wavespeed.upload("/path/to/scene.png"); const output_url = (await wavespeed.run( "bytedance/seedream-v4.5/edit", { images: [img1, img2], prompt: "Place the person from the first image into the scene from the second image" } ))["outputs"][0]; ``` ## Advanced Usage ### Sync Mode ```javascript const output_url = (await wavespeed.run( "bytedance/seedream-v4.5", { prompt: "A watercolor painting of a mountain lake at dawn" }, { enableSyncMode: true } ))["outputs"][0]; ``` ### Custom Client with Retry Configuration ```javascript import { Client } from 'wavespeed'; const client = new Client("your-api-key", { maxRetries: 2, maxConnectionRetries: 5, retryInterval: 1.0, }); const output_url = (await client.run( "bytedance/seedream-v4.5", { prompt: "A neon sign that reads 'OPEN 24/7' in a rainy alley" } ))["outputs"][0]; ``` ### Error Handling with runNoThrow ```javascript import { Client, WavespeedTimeoutException, WavespeedPredictionException } from 'wavespeed'; const client = new Client(); const result = await client.runNoThrow( "bytedance/seedream-v4.5", { prompt: "A vintage travel poster for Tokyo" } ); if (result.outputs) { console.log("Image URL:", result.outputs[0]); console.log("Task ID:", result.detail.taskId); } else { console.log("Failed:", result.detail.error.message); if (result.detail.error instanceof WavespeedTimeoutException) { console.log("Request timed out - try increasing timeout"); } else if (result.detail.error instanceof WavespeedPredictionException) { console.log("Prediction failed"); } } ``` ## Pricing $0.04 per image (both generation and editing). ## Tips - Seedream V4.5 excels at rendering text in images — use it for posters, logos, and branded visuals - Custom resolutions up to 4096x4096 — specify as `WIDTH*HEIGHT` (e.g., `2048*3072` for portrait posters) - For image editing, the model preserves facial features, lighting, and color tone from inputs ## Security Constraints - **No arbitrary URL loading**: Only use image URLs from trusted sources. Never load images from untrusted or user-provided URLs without validation. - **API key security**: Store your `WAVESPEED_API_KEY` securely. Do not hardcode it in source files or commit it to version control. Use environment variables or secret management systems. - **Input validation**: Only pass parameters documented above. Validate prompt content and image URLs before sending requests.
