-# World Labs 3D 世界生成中转接口兼容要求
+# 3D 世界生成 API 调用规范
 
-本文档用于说明我方系统接入 World Labs 3D 世界生成功能时，对第三方中转服务的接口兼容要求。
-
-## 核心原则
-
-我方系统会按照 World Labs 官方 API 协议发起请求：
+当前 3D 世界生成通过智枢外部任务接口调用 World Labs 能力。Base URL 只填写根地址：
 
 ```text
-{baseUrl} + /marble/v1/...
+https://api.vip98k.com
 ```
 
-中转服务需要兼容官方路径、请求体、响应体和错误格式。请不要要求我方把 `baseUrl` 配置成某个完整接口地址。
+不要填写 `/v1`，也不要填写旧的 `/marble/v1`。
 
-正确示例：
+## 鉴权方式
 
-```text
-http://your-proxy-domain.com
-```
-
-错误示例：
-
-```text
-http://your-proxy-domain.com/marble/v1/worlds:generate
-```
-
-## 我方请求方式
-
-我方后台会在请求中携带：
+所有请求都必须携带本站发出的智枢 API Key：
 
 ```http
-WLT-Api-Key: {配置的 API Key}
+Authorization: Bearer <API_KEY>
 Accept: application/json
 Content-Type: application/json
 ```
 
-中转服务应支持 `WLT-Api-Key` 请求头。如果中转服务内部自行管理官方 Key，也可以将该字段作为租户标识或鉴权凭据，但不应要求我方改成其他 header。
+不要使用管理员 Key、其他平台 Key，也不要使用旧的 `WLT-Api-Key` 作为主链路鉴权。
 
-## 必须兼容的接口
+## 模型目录
 
-### 1. 准备上传素材
+正式创建任务前，可以先确认这把 Key 是否开通空间生成分组：
 
-```http
-POST {baseUrl}/marble/v1/media-assets:prepare_upload
+```bash
+curl "https://api.vip98k.com/api/external/task/models" \
+  -H "Authorization: Bearer <API_KEY>"
 ```
 
-请求体示例：
+返回内容里应能找到：
 
 ```json
 {
-  "file_name": "input.jpg",
-  "extension": "jpg",
-  "kind": "image",
-  "metadata": {
-    "mime_type": "image/jpeg",
-    "uploaded_from": "canvas_world_mode"
+  "modelId": "world-generation"
+}
+```
+
+如果找不到，说明这把 Key 没有勾选空间生成分组。
+
+## 创建任务
+
+```bash
+curl "https://api.vip98k.com/api/external/task/generate" \
+  -X POST \
+  -H "Authorization: Bearer <API_KEY>" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "world-generation",
+    "displayName": "Test scene",
+    "prompt": "A quiet sunlit courtyard with a small stone fountain."
+  }'
+```
+
+正常会先返回 `accepted` 或 `running`，这不是失败：
+
+```json
+{
+  "data": {
+    "taskId": "任务ID",
+    "status": "accepted",
+    "done": false,
+    "resultPath": "/api/external/task/result?taskId=任务ID"
   }
 }
 ```
 
-响应必须包含可用的上传信息：
+## 查询结果
+
+```bash
+curl "https://api.vip98k.com/api/external/task/result?taskId=<任务ID>" \
+  -H "Authorization: Bearer <API_KEY>"
+```
+
+建议每隔 5 到 10 秒查询一次，最长等待 10 分钟。直到返回：
 
 ```json
 {
-  "media_asset": {},
-  "upload_info": {
-    "upload_url": "https://...",
-    "upload_method": "PUT",
-    "required_headers": {}
+  "data": {
+    "status": "succeeded",
+    "done": true
   }
 }
 ```
 
-要求：
+## 常见错误
 
-- `upload_url` 必须可由我方服务器直接访问。
-- `upload_method` 如为 `PUT`，必须支持 `PUT` 上传文件二进制。
-- `required_headers` 中返回的 header，我方会原样带上。
-- 上传成功时，上传地址必须返回 `2xx`。
-
-### 2. 创建世界生成任务
-
-```http
-POST {baseUrl}/marble/v1/worlds:generate
-```
-
-请求体示例：
-
-```json
-{
-  "display_name": "",
-  "model": "marble-1.1",
-  "permission": {
-    "public": false
-  },
-  "world_prompt": {
-    "type": "image",
-    "image_prompt": {
-      "source": "media_asset",
-      "media_asset_id": "media_asset_id_here"
-    }
-  }
-}
-```
-
-响应需兼容官方 operation 结构，至少包含：
-
-```json
-{
-  "operation_id": "task-id",
-  "done": false,
-  "metadata": {
-    "progress": {
-      "status": "RUNNING"
-    }
-  }
-}
-```
-
-要求：
-
-- `operation_id` 必须稳定，后续查询状态必须使用同一个 id。
-- 不要在创建成功但任务未完成时返回业务失败。
-- 如果余额不足、Key 无效，应返回明确 HTTP 状态码和错误信息。
-
-### 3. 查询任务状态
-
-```http
-GET {baseUrl}/marble/v1/operations/{operation_id}
-```
-
-运行中响应示例：
-
-```json
-{
-  "operation_id": "task-id",
-  "done": false,
-  "metadata": {
-    "progress": {
-      "status": "RUNNING",
-      "description": "World generation in progress"
-    }
-  }
-}
-```
-
-成功响应示例：
-
-```json
-{
-  "operation_id": "task-id",
-  "done": true,
-  "error": null,
-  "metadata": {
-    "progress": {
-      "status": "SUCCEEDED"
-    },
-    "world_id": "world-id"
-  },
-  "response": {
-    "world_id": "world-id",
-    "world_marble_url": "https://marble.worldlabs.ai/world/...",
-    "assets": {
-      "mesh": {
-        "collider_mesh_url": "https://cdn.marble.worldlabs.ai/.../model.glb"
-      },
-      "imagery": {
-        "pano_url": "https://cdn.marble.worldlabs.ai/.../rgb_0.png"
-      },
-      "thumbnail_url": "https://cdn.marble.worldlabs.ai/.../thumbnail.webp",
-      "splats": {
-        "spz_urls": {
-          "100k": "https://cdn.marble.worldlabs.ai/...100k.spz",
-          "150k": "https://cdn.marble.worldlabs.ai/...150k.spz",
-          "500k": "https://cdn.marble.worldlabs.ai/...500k.spz",
-          "full_res": "https://cdn.marble.worldlabs.ai/...full.spz"
-        }
-      }
-    }
-  }
-}
-```
-
-失败响应示例：
-
-```json
-{
-  "operation_id": "task-id",
-  "done": true,
-  "error": {
-    "message": "Insufficient account balance"
-  }
-}
-```
-
-要求：
-
-- `done=false` 表示任务仍在运行。
-- `done=true` 且 `error=null` 表示任务成功。
-- `done=true` 且 `error.message` 存在表示任务失败。
-- 不要把运行中的任务返回为 HTTP 404。
-- 不要因为任务未完成就返回 `Operation not found`。
-
-### 4. 查询世界详情
-
-```http
-GET {baseUrl}/marble/v1/worlds/{world_id}
-```
-
-当 `operations` 成功响应中资产不完整时，我方会调用该接口补充详情。响应应包含与 `response` 内 world 对象兼容的数据结构。
-
-## 错误码要求
-
-建议按以下语义返回：
-
-| 场景 | HTTP 状态码 | message 示例 |
-| --- | --- | --- |
-| API Key 缺失或无效 | `401` | `Unauthorized` |
-| 权限不足 | `403` | `Forbidden` |
-| 余额不足 | `402` 或 `403` | `Insufficient account balance` |
-| 请求体错误 | `400` | `Invalid request body` |
-| 任务不存在 | `404` | `Operation not found` |
-| 上游超时 | `504` | `Upstream timeout` |
-| 上游异常 | `502` | `Upstream error` |
-
-响应体建议：
-
-```json
-{
-  "message": "Insufficient account balance"
-}
-```
-
-或：
-
-```json
-{
-  "error": {
-    "message": "Insufficient account balance"
-  }
-}
-```
-
-## 超时与稳定性要求
-
-- `prepare_upload` 建议 30 秒内返回。
-- `worlds:generate` 建议 60 秒内返回 operation，而不是等待生成完成。
-- `operations/{id}` 建议 10 秒内返回当前状态。
-- 生成任务本身可异步运行，前端会轮询状态。
-- 同一个 `operation_id` 多次查询必须返回同一个任务状态，不应随机切换账号或路由。
-
-## 上传地址要求
-
-`prepare_upload` 返回的 `upload_url` 可以是官方签名地址，也可以是中转服务自己的上传地址，但必须满足：
-
-- 我方服务器可直接访问。
-- 支持返回的 `upload_method`。
-- 支持上传原始文件二进制。
-- 上传成功返回 `2xx`。
-- 上传完成后，后续 `worlds:generate` 使用的 `media_asset_id` 必须可用。
-
-## 安全要求
-
-- 不要在错误信息中返回完整官方 API Key。
-- 日志中建议只记录 Key 前后少量字符，例如 `sk-****abcd`。
-- 中转服务如保存官方 Key，应加密存储。
-- 上传 URL 如有签名，应设置合理过期时间。
-- 不要允许用户通过 `baseUrl` 或 path 注入访问内网地址。
-
-## 我方验收用例
-
-中转服务上线前，请至少通过以下链路：
-
-1. `POST /marble/v1/media-assets:prepare_upload` 返回 `media_asset_id` 和可上传 URL。
-2. 使用返回的 `upload_url` 上传图片，返回 `2xx`。
-3. `POST /marble/v1/worlds:generate` 返回稳定 `operation_id`。
-4. `GET /marble/v1/operations/{operation_id}` 在运行中返回 `done=false`。
-5. 任务完成后返回 `done=true`、`error=null`、`world_id` 和资产 URL。
-6. 资产 URL 中至少应包含 thumbnail、pano、mesh 或 spz 中的一种，最好完整返回。
-7. `GET /marble/v1/worlds/{world_id}` 可返回完整 world 详情。
-
-## 配置示例
-
-我方系统中的 API 地址应填写中转根地址：
-
-```text
-http://23.169.168.133:8080
-```
-
-最终我方会请求：
-
-```text
-http://23.169.168.133:8080/marble/v1/media-assets:prepare_upload
-http://23.169.168.133:8080/marble/v1/worlds:generate
-http://23.169.168.133:8080/marble/v1/operations/{operation_id}
-http://23.169.168.133:8080/marble/v1/worlds/{world_id}
-```
-
-如果切回官方接口，配置为：
-
-```text
-https://api.worldlabs.ai
-```
-
-最终请求：
-
-```text
-https://api.worldlabs.ai/marble/v1/media-assets:prepare_upload
-https://api.worldlabs.ai/marble/v1/worlds:generate
-https://api.worldlabs.ai/marble/v1/operations/{operation_id}
-https://api.worldlabs.ai/marble/v1/worlds/{world_id}
-```
-
-## 结论
-
-中转服务需要做的是兼容 World Labs 官方 API 协议，而不是要求我方修改接口路径。只要中转根地址完整支持 `/marble/v1/...`，我方系统就可以在官方接口和中转接口之间无缝切换。
+- 不能用 `/v1/chat/completions`。
+- 不能把模型写成 `marble-1.1`。
+- 不能把 `accepted` 或 `running` 当作调用失败。
+- 不能只等待几十秒就判定超时。
+- 必须携带 `Authorization: Bearer <API_KEY>`。
