# Wan Text-to-Image

## 概览

使用支持的模型创建异步文生视频任务。使用返回的任务 ID 查询状态，或提供 callback_url 接收终态投递。

### 快速开始

1. 创建 API Key，并将其设置为 RUNAPI_API_KEY。
2. 选择一个支持的模型，并发送与该模型 Schema 匹配的 POST 请求。
3. 保存返回的任务 ID，随后轮询到终态，或处理终态回调。

## 端点

POST /api/v1/wan/text_to_image

基础 URL: https://runapi.ai

API 版本: v1

身份验证: Authorization: Bearer YOUR_API_TOKEN

## 支持的模型

打开模型页可查看当前价格、限流和商业使用详情。

- [wan-2.7-image](/models/wan/2.7-image)
- [wan-2.7-image-pro](/models/wan/2.7-image-pro)

## 请求 Schema

字段和允许的取值取决于所选模型。提供 callback_url 后，它会收到任务终态投递。
