# 步骤 1：包和清单

{
"id": "acme-ai",
"name": "Acme AI",
"description": "Acme AI model provider",
"providers": ["acme-ai"],
"modelSupport": {
  "modelPrefixes": ["acme-"]
},
"providerAuthEnvVars": {
  "acme-ai": ["ACME_AI_API_KEY"]
},
"providerAuthAliases": {
  "acme-ai-coding": "acme-ai"
},
"providerAuthChoices": [
  {
    "provider": "acme-ai",

    "choiceId": "acme-ai-api-key",
    "choiceLabel": "Acme AI API key",
    "groupId": "acme-ai",
    "groupLabel": "Acme AI",

    "cliDescription": "Acme AI API key"
  }
],

}

清单声明了 providerAuthEnvVars，这样 OpenClaw 可以在不加载你的插件运行时的情况下检测凭证。当某个提供商变体应复用另一个提供商 id 的凭证时，请添加 providerAuthAliases。modelSupport 是可选的，它允许 OpenClaw 在运行时钩子存在之前，根据 acme-large 这样的模型简写 id 自动加载你的提供商插件。如果你在 ClawHub 上发布该提供商，则 package.json 中必须包含这些 openclaw.compat 和 openclaw.build 字段。

Register the provider

一个最小提供商需要 id、label、auth 和 catalog：

import { definePluginEntry } from "openclaw/plugin-sdk/plugin-entry";
import { createProviderApiKeyAuthMethod } from "openclaw/plugin-sdk/provider-auth";

export default definePluginEntry({
  id: "acme-ai",
  name: "Acme AI",
  description: "Acme AI model provider",
  register(api) {
    api.registerProvider({
      id: "acme-ai",
      label: "Acme AI",
      docsPath: "/providers/acme-ai",
      envVars: ["ACME_AI_API_KEY"],

      auth: [
        createProviderApiKeyAuthMethod({
          providerId: "acme-ai",
          methodId: "api-key",
          label: "Acme AI API key",
          hint: "API key from your Acme AI dashboard",
          optionKey: "acmeAiApiKey",
          flagName: "--acme-ai-api-key",
          envVar: "ACME_AI_API_KEY",
          promptMessage: "Enter your Acme AI API key",
          defaultModel: "acme-ai/acme-large",
        }),
      ],

      catalog: {
        order: "simple",
        run: async (ctx) => {
          const apiKey =
            ctx.resolveProviderApiKey("acme-ai").apiKey;
          if (!apiKey) return null;
          return {
            provider: {
              baseUrl: "https://api.acme-ai.com/v1",
              apiKey,
              api: "openai-completions",
              models: [
                {
                  id: "acme-large",
                  name: "Acme Large",
                  reasoning: true,
                  input: ["text", "image"],
                  cost: { input: 3, output: 15, cacheRead: 0.3, cacheWrite: 3.75 },
                  contextWindow: 200000,
                  maxTokens: 32768,
                },
                {
                  id: "acme-small",
                  name: "Acme Small",
                  reasoning: false,
                  input: ["text"],
                  cost: { input: 1, output: 5, cacheRead: 0.1, cacheWrite: 1.25 },
                  contextWindow: 128000,
                  maxTokens: 8192,
                },
              ],
            },
          };
        },
      },
    });
  },
});

这就是一个可工作的提供商。用户现在可以运行 openclaw onboard --acme-ai-api-key <key>，并选择 acme-ai/acme-large 作为他们的模型。

如果上游提供商使用的控制令牌与 OpenClaw 不同，请添加一个小型双向文本转换，而不是替换流路径：

api.registerTextTransforms({
  input: [
    { from: /red basket/g, to: "blue basket" },
    { from: /paper ticket/g, to: "digital ticket" },
    { from: /left shelf/g, to: "right shelf" },
  ],
  output: [
    { from: /blue basket/g, to: "red basket" },
    { from: /digital ticket/g, to: "paper ticket" },
    { from: /right shelf/g, to: "left shelf" },
  ],
});

input 会在传输前重写最终系统提示词和文本消息内容。output 会在 OpenClaw 解析自己的控制标记或进行渠道投递之前，重写助手文本增量和最终文本。

对于只注册一个带有 API key 凭证和单一目录支持运行时的文本提供商的内置提供商，优先使用更窄的 defineSingleProviderPluginEntry(...) 辅助函数：

import { defineSingleProviderPluginEntry } from "openclaw/plugin-sdk/provider-entry";

export default defineSingleProviderPluginEntry({
  id: "acme-ai",
  name: "Acme AI",
  description: "Acme AI model provider",
  provider: {
    label: "Acme AI",
    docsPath: "/providers/acme-ai",
    auth: [
      {
        methodId: "api-key",
        label: "Acme AI API key",
        hint: "API key from your Acme AI dashboard",
        optionKey: "acmeAiApiKey",
        flagName: "--acme-ai-api-key",
        envVar: "ACME_AI_API_KEY",
        promptMessage: "Enter your Acme AI API key",
        defaultModel: "acme-ai/acme-large",
      },
    ],
    catalog: {
      buildProvider: () => ({
        api: "openai-completions",
        baseUrl: "https://api.acme-ai.com/v1",
        models: [{ id: "acme-large", name: "Acme Large" }],
      }),
      buildStaticProvider: () => ({
        api: "openai-completions",
        baseUrl: "https://api.acme-ai.com/v1",
        models: [{ id: "acme-large", name: "Acme Large" }],
      }),
    },
  },
});

buildProvider 是 OpenClaw 能解析真实提供商凭证时使用的实时目录路径。它可以执行提供商特定的发现。仅将 buildStaticProvider 用于在配置凭证之前可安全展示的离线行；它不得需要凭证或发起网络请求。OpenClaw 的 models list --all 显示目前仅对内置提供商插件执行静态目录，并使用空配置、空环境，且没有智能体/工作区路径。

如果你的凭证流程还需要在新手引导期间修补 models.providers.*、别名和智能体默认模型，请使用 openclaw/plugin-sdk/provider-onboard 中的预设辅助函数。最窄的辅助函数是 createDefaultModelPresetAppliers(...)、 createDefaultModelsPresetAppliers(...) 和 createModelCatalogPresetAppliers(...)。

当提供商的原生端点在常规 openai-completions 传输上支持流式 usage 块时，优先使用 openclaw/plugin-sdk/provider-catalog-shared 中的共享目录辅助函数，而不是硬编码提供商 id 检查。supportsNativeStreamingUsageCompat(...) 和 applyProviderNativeStreamingUsageCompat(...) 会从端点能力映射中检测支持情况，因此即使插件使用自定义提供商 id，原生 Moonshot/DashScope 风格端点仍会选择启用。

Add dynamic model resolution

如果你的提供商接受任意模型 ID（例如代理或路由器），请添加 resolveDynamicModel：

api.registerProvider({
  // ... id, label, auth, catalog from above

  resolveDynamicModel: (ctx) => ({
    id: ctx.modelId,
    name: ctx.modelId,
    provider: "acme-ai",
    api: "openai-completions",
    baseUrl: "https://api.acme-ai.com/v1",
    reasoning: false,
    input: ["text"],
    cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
    contextWindow: 128000,
    maxTokens: 8192,
  }),
});

如果解析需要网络调用，请使用 prepareDynamicModel 进行异步预热 - 完成后 resolveDynamicModel 会再次运行。

Add runtime hooks (as needed)

大多数提供商只需要 catalog + resolveDynamicModel。根据你的提供商需求逐步添加钩子。

共享辅助构建器现在覆盖了最常见的重放/工具兼容系列，因此插件通常不需要逐个手动接线每个钩子：

import { buildProviderReplayFamilyHooks } from "openclaw/plugin-sdk/provider-model-shared";
import { buildProviderStreamFamilyHooks } from "openclaw/plugin-sdk/provider-stream";
import { buildProviderToolCompatFamilyHooks } from "openclaw/plugin-sdk/provider-tools";

const GOOGLE_FAMILY_HOOKS = {
  ...buildProviderReplayFamilyHooks({ family: "google-gemini" }),
  ...buildProviderStreamFamilyHooks("google-thinking"),
  ...buildProviderToolCompatFamilyHooks("gemini"),
};

api.registerProvider({
  id: "acme-gemini-compatible",
  // ...
  ...GOOGLE_FAMILY_HOOKS,
});

当前可用的重放系列：

当前可用的流系列：

prepareRuntimeAuth: async (ctx) => {
  const exchanged = await exchangeToken(ctx.apiKey);
  return {
    apiKey: exchanged.token,
    baseUrl: exchanged.baseUrl,
    expiresAt: exchanged.expiresAt,
  };
},

// wrapStreamFn returns a StreamFn derived from ctx.streamFn
wrapStreamFn: (ctx) => {
  if (!ctx.streamFn) return undefined;
  const inner = ctx.streamFn;
  return async (params) => {
    params.headers = {
      ...params.headers,
      "X-Acme-Version": "2",
    };
    return inner(params);
  };
},

resolveTransportTurnState: (ctx) => ({
  headers: {
    "x-request-id": ctx.turnId,
  },
  metadata: {
    session_id: ctx.sessionId ?? "",
    turn_id: ctx.turnId,
  },
}),
resolveWebSocketSessionPolicy: (ctx) => ({
  headers: {
    "x-session-id": ctx.sessionId ?? "",
  },
  degradeCooldownMs: 60_000,
}),

resolveUsageAuth: async (ctx) => {
  const auth = await ctx.resolveOAuthToken();
  return auth ? { token: auth.token } : null;
},
fetchUsageSnapshot: async (ctx) => {
  return await fetchAcmeUsage(ctx.token, ctx.timeoutMs);
},

添加额外能力（可选）

# 步骤 5：添加额外能力

提供商插件可以在文本推理之外，同时注册语音、实时转录、实时语音、媒体理解、图像生成、视频生成、Web 抓取和 Web 搜索。OpenClaw 将这类插件归类为 混合能力插件 - 这是公司插件的推荐模式 （每个供应商一个插件）。请参阅 内部机制：能力所有权。

在 register(api) 中与现有的 api.registerProvider(...) 调用一起注册每项能力。只选择你需要的标签页：

import {
  assertOkOrThrowProviderError,
  postJsonRequest,
} from "openclaw/plugin-sdk/provider-http";

api.registerSpeechProvider({
  id: "acme-ai",
  label: "Acme Speech",
  isConfigured: ({ config }) => Boolean(config.messages?.tts),
  synthesize: async (req) => {
    const { response, release } = await postJsonRequest({
      url: "https://api.example.com/v1/speech",
      headers: new Headers({ "Content-Type": "application/json" }),
      body: { text: req.text },
      timeoutMs: req.timeoutMs,
      fetchFn: fetch,
      auditContext: "acme speech",
    });
    try {
      await assertOkOrThrowProviderError(response, "Acme Speech API error");
      return {
        audioBuffer: Buffer.from(await response.arrayBuffer()),
        outputFormat: "mp3",
        fileExtension: ".mp3",
        voiceCompatible: false,
      };
    } finally {
      await release();
    }
  },
});

api.registerRealtimeTranscriptionProvider({

      callbacks: req,
      url: "wss://api.example.com/v1/realtime-transcription",
      headers: { Authorization: `Bearer ${apiKey}` },
      onMessage: (event, transport) => {
        if (event.type === "session.created") {
          transport.sendJson({ type: "session.update" });
          transport.markReady();
          return;
        }
        if (event.type === "transcript.final") {
          req.onTranscript?.(event.text);
        }
      },
      sendAudio: (audio, transport) => {
        transport.sendJson({
          type: "audio.append",
          audio: audio.toString("base64"),
        });

    supportsBargeIn: true,
    supportsToolCalls: true,
  },
  isConfigured: ({ providerConfig }) => Boolean(providerConfig.apiKey),
  createBridge: (req) => ({
    // Set this only if the provider accepts multiple tool responses for

    // the final result.
    supportsToolResultContinuation: false,
    connect: async () => {},

测试

# 步骤 6：测试

import { describe, it, expect } from "vitest";
// Export your provider config object from index.ts or a dedicated file
import { acmeProvider } from "./provider.js";

describe("acme-ai provider", () => {
  it("resolves dynamic models", () => {
    const model = acmeProvider.resolveDynamicModel!({
      modelId: "acme-beta-v3",
    } as any);
    expect(model.id).toBe("acme-beta-v3");
    expect(model.provider).toBe("acme-ai");
  });

  it("returns catalog when key is available", async () => {
    const result = await acmeProvider.catalog!.run({
      resolveProviderApiKey: () => ({ apiKey: "test-key" }),
    } as any);
    expect(result?.provider?.models).toHaveLength(2);
