> ## Agent Instructions
> Send API requests to https://api.ttapi.io with the TT-API-KEY header. Midjourney account hosting uses https://hold.ttapi.io. Claude Code uses https://cc.ttapi.io.
> Most generation endpoints are asynchronous. The submit response returns a job id. Poll that product's fetch endpoint, or pass a webhook on the submit request. A fetch call does not start a new generation.
> 1 USD = 100 quota. Check the pricing page for that product before estimating cost.
> This file lists the English docs. Follow every /_llms/ link recursively for the API reference, Chinese, and Russian. Open a page's .md URL for the endpoint schema.

# Midjourney API 工作流 | Imagine vs Action vs Blend vs Inpaint

> 在 TTAPI 上选择合适的 Midjourney API 接口，对比 imagine、action、blend、describe、seed、inpaint 和 fetch 的适用场景。

# Midjourney API 工作流

当需要为特定产品场景选择正确的 **Midjourney API** 接口时，参考本指南。

## 接口对比

| 接口 | 适用场景 |
| :- | :- |
| [Imagine](/api/cn/midjourney/imagine) | 基于提示词生成图像 |
| [Action](/api/cn/midjourney/action) | 对已完成结果进行放大、变体、重排、平移和缩放 |
| [Blend](/api/cn/midjourney/blend) | 合并多张源图片 |
| [Describe](/api/cn/midjourney/describe) | 将图片转换为提示词文本 |
| [Seed](/api/cn/midjourney/seed) | 获取生成种子值 |
| [Inpaint](/api/cn/midjourney/inpaint) | 编辑图像的选定区域 |
| [Fetch](/api/cn/midjourney/fetch) | 轮询异步任务状态和输出 |

## Imagine vs Action

* 使用 [Imagine](/api/cn/midjourney/imagine) 开始一个全新任务
* 使用 [Action](/api/cn/midjourney/action) 对已完成的生成结果进行后续操作

## Blend vs Inpaint

* 使用 [Blend](/api/cn/midjourney/blend) 将多张图片合并为新结果
* 使用 [Inpaint](/api/cn/midjourney/inpaint) 编辑已有图片的指定区域

## Describe vs Seed

* 使用 [Describe](/api/cn/midjourney/describe) 从图片获取文本提示词
* 使用 [Seed](/api/cn/midjourney/seed) 查看或复用生成种子信息

## 推荐起始点

| 目标 | 起始接口 |
| :- | :- |
| 根据提示词生成图片 | [Midjourney Imagine API](/api/cn/midjourney/imagine) |
| 继续处理已有结果 | [Midjourney Action API](/api/cn/midjourney/action) |
| 混合参考图片 | [Midjourney Blend API](/api/cn/midjourney/blend) |
| 区域编辑 | [Midjourney Inpaint API](/api/cn/midjourney/inpaint) |
| 查询异步状态 | [Midjourney Fetch API](/api/cn/midjourney/fetch) |
