Seedream API JavaScript SDK for RunAPI

The seedream api JavaScript SDK is the language-specific package for Seedream on RunAPI. Use this seedream api package for text-to-image, image editing, and creative production flows when your application needs JSON request bodies, task status lookup, and consistent RunAPI errors in JavaScript.

This seedream api README is the JavaScript package guide inside the public seedream-sdk repository. For the repository overview, start at ../README.md; for model details, use https://runapi.ai/models/seedream; for API reference, use https://runapi.ai/docs#seedream; for SDK docs, use https://runapi.ai/docs#sdk-seedream.

Install

npm install @runapi.ai/seedream

Quick start

import { SeedreamClient } from '@runapi.ai/seedream';

const client = new SeedreamClient();
const task = await client.textToImage.create({
  model: 'seedream-v4-text-to-image',
  prompt: 'A precise product render of a glass teapot on white marble',
  aspect_ratio: '16:9',
  output_resolution: '2k',
  output_count: 3,
});
const status = await client.textToImage.get(task.id);

Use create when you want to submit a task and return quickly, get when you need the latest task state, and run when a script should create and poll until completion. In web request handlers, prefer create plus webhook or later get polling so a worker is not held open.

RunAPI-generated file URLs are temporary. Download and store generated images, videos, audio, or other files in your own durable storage within 7 days; do not treat returned URLs as long-term assets.

Language notes

Use the TypeScript types in src/types.ts and the resource classes under src/resources when building image applications. The package exposes textToImage for text models and editImage for editing models. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
