  "documentation": "# KM 可美 Seedream 5.0\n\n`yingce.plugin/v2` 声明式图片协议包。使用渠道凭证，宿主统一负责 HTTPS、SSRF 校验、超时与媒体持久化；不包含脚本运行时或密钥。\n\n适配精确模型 ID：`doubao-seedream-5-0-pro-260628`、`doubao-seedream-5-0-flash-260915`。\n\n选择协议时“能力与参数”默认设为：2K / 1:1（2048x2048）、单张生成、最多 10 张参考图、单图 30 MB、关闭蒙版、关闭通用 quality 和透明背景开关。1K / 1.5K / 2K 各有八种官方精确尺寸。响应默认 URL、输出 JPEG、关闭水印；所有返回图片及用量交给宿主消费。\n\n详情见 [接口说明](docs/interface.md)。\n\n---\n\n# KM 可美 Seedream 5.0 接口\n\n## 来源与范围\n\n- [供应商图像文档](https://token.xinhankr.com/docs/quickstart/doc0002)，公开文档 `volc-image`：OpenAI 兼容端点、Pro 的限制与默认值。\n- [火山引擎 Image generation API](https://docs.volcengine.com/docs/ark/image-generation-api?lang=zh&redirect=1)：Pro / Flash 的精确模型 ID、尺寸、参考图、格式和能力限制。\n- 供应商模型市场确认两个精确模型 ID 可用。市场计费档不是参考图或组图数量上限。\n\n## 请求\n\n`POST https://token.xinhankr.com/v1/images/generations`，JSON，渠道 API Key 作为 Bearer Token。\n\n```json\n{\n  \"model\": \"doubao-seedream-5-0-pro-260628\",\n  \"prompt\": \"暖色书房中的橘猫，写实照片，正方形构图\",\n  \"n\": 1,\n  \"size\": \"2048x2048\",\n  \"response_format\": \"url\",\n  \"output_format\": \"jpeg\",\n  \"watermark\": false,\n  \"background\": \"opaque\"\n}\n```\n\nFlash 使用 `doubao-seedream-5-0-flash-260915`。图生图仍使用同一端点；参考图映射为 `image`，单图是字符串，多图是数组，保持输入顺序，支持 URL / Base64。最多 10 张，每张不超过 30 MB。官方还要求参考图边长大于 14、总像素 196–36000000、比例 1:16–16:1；这些条件需素材本身满足。没有蒙版接口。\n\n`size` 支持 `1K` / `1.5K` / `2K`，或像素字符串。空值 / auto 默认 2K；宿主比例值映射为官方 2K 像素。自定义总像素 921600–4624220，比例 1:16–16:1。宿主交互控件还保留全站的 16px 步长、最长边 3840 与 3:1 比例约束。提示词 32000 字符是宿主限制，未声称是供应商的上限。\n\n| 比例 | 1K | 1.5K | 2K |\n| --- | --- | --- | --- |\n| 1:1 | 1024x1024 | 1536x1536 | 2048x2048 |\n| 4:3 | 1152x864 | 1792x1344 | 2368x1776 |\n| 3:4 | 864x1152 | 1344x1792 | 1776x2368 |\n| 16:9 | 1424x800 | 2048x1152 | 2816x1584 |\n| 9:16 | 800x1424 | 1152x2048 | 1584x2816 |\n| 3:2 | 1248x832 | 1872x1248 | 2496x1664 |\n| 2:3 | 832x1248 | 1248x1872 | 1664x2496 |\n| 21:9 | 1568x672 | 2352x1008 | 3136x1344 |\n\n## 命名空间扩展\n\n`providerOptions.km-kemei-seedream`：\n\n- `response_format`：url（默认）/ b64_json。\n- `output_format`：jpeg（默认）/ png。\n- `watermark`：false（默认）/ true。\n- `background`：opaque（默认）/ transparent。透明只用于一张带 alpha 的输入图，且输出 png；插件校验单图与 png 条件，alpha 条件由供应商检查。宿主通用透明开关默认关闭，避免把任意文生图伪装成此能力。\n- `layer_decomposition`：布尔值，仅一张输入图，尺寸使用档位或 auto；此时允许空提示词，保存全部图层，不按 n=1 截断。\n\nPro / Flash 不支持 sequential_image_generation、组图、联网搜索、流式输出。插件拒绝相关扩展字段，不发送通用 quality、resolution、seed。\n\n## 响应与失败\n\n同步响应中的 `data[]` 全部提取，兼容 url / b64_json，并透传 usage。供应商 URL 有有效期，宿主必须持久化结果。HTTP 错误由宿主处理，JSON 的 error.code / error.message 映射为失败；不以空结果冒充成功。\n\n安装包不携带渠道密钥；管理员通过正常插件安装机制启用，再给渠道模型选择此协议。模型价格与启用状态由管理员独立配置。\n\n<!-- YINGCE_MANIFEST_CONTRACT_START -->\n## Manifest 完整接口定义\n\n以下 JSON 与插件包内实际 `manifest.json` 逐字段一致，覆盖插件身份、权限、配置、鉴权、参数、校验、创建、Agent、查询、取消、结果下载、响应和 Agent 响应映射。`documentation` 字段的值就是当前完整文档；为避免文档在自身内部无限递归，JSON 中仅用等义占位文本表示正文。\n\n```json\n{\n  \"apiVersion\":
