概覽

AI 產生的概覽

讓助理以按次付費方式使用 DDG 代理服務目錄,涵蓋網頁搜尋、擷取、AI、安全與加密支付等大量端點。

功能
把助理連接到 DDG 的代理付費服務閘道,開放約 170 個可呼叫端點。這些端點涵蓋網頁搜尋與擷取、社群與金融資料、AI 對話、向量嵌入、影像生成、摘要、安全稽核、區塊鏈查詢、文件與 OCR 擷取、實用工具,以及加密的代理間郵件。它也提供相容於 OpenAI 的閘道,以及探索、定價與就緒狀態資源。
適用情境
當助理需要透過單一付費閘道取得許多小型、按量計費的能力,而不想分別安裝多個工具時使用。適合已能處理加密貨幣支付,並希望隨需使用搜尋、擷取、AI 推論或安全檢查的代理。
執行需求
以本機 Python 套件透過 stdio 執行。需要 Python 與 ddg-agent-services-mcp 套件。需要環境變數 DDG_MCP_AGENT_ID,可選 DDG_AGENT_SERVICES_BASE_URL 與 DDG_AGENT_SERVICES_ALLOWED_HOSTS。付款使用 EVM 錢包私鑰與 x402 等加密通道;需要連線至 DDG 服務的網路存取。
安裝前請注意
大多數呼叫都要付費,從不到一分錢到 0.25 美元不等,並以加密貨幣自動結算,花費可能累積。設定涉及錢包私鑰,屬於高價值機密,應避免寫入日誌或共用設定。呼叫會把資料傳送到第三方服務,部分端點還會抓取或代理外部網址,請先確認傳送的內容。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 DDG Agent-Payable Services MCP,將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only,透過 STDIO。 STDIO 服務會啟動本機處理程序,因此需要 SourceWeft 桌面主機。

DDG Agent-Payable Services

Pay-per-call AI agent services gateway. DDG gives agents one x402/direct-crypto entry point for callable tools, OpenAI-compatible routes, readiness audits, MCP security checks, discovery repair, receipts, and marketplace-ready proof artifacts.

170 x402/direct-crypto services for AI agents. The largest agent-payable service surface in the x402 ecosystem — from $0.001 utilities (DNS, hash, UUID) to $0.01 social/financial/agent-infra services. All fully automated with zero human in the loop. Includes an OpenAI-compatible gateway (/v1/chat/completions, /v1/models, /v1/embeddings).

Quick Start

One-liner SDK (zero framework deps)

python
from ddg_agent_services_mcp import ddg
client = ddg(agent_id="my-agent", private_key="0x...")result = client.post("/v1/site-audit", {"url": "https://example.com"})

Or configure once via environment:

bash
export DDG_AGENT_ID="my-agent"export DDG_PRIVATE_KEY="0x..."
python
from ddg_agent_services_mcp import ddgclient = ddg()  # reads from env

OpenAI-compatible gateway

Drop-in replacement for openai-python — point any OpenAI client at DDG:

python
from ddg_agent_services_mcp import create_openai_client
client = create_openai_client(agent_id="my-agent", private_key="0x...")response = client.chat.completions.create(    model="auto",    messages=[{"role": "user", "content": "Hello"}],)print(response.choices[0].message.content)

Supported routes: GET /v1/models, POST /v1/chat/completions, POST /v1/embeddings

Or use the standard openai package directly:

python
from openai import OpenAIclient = OpenAI(    base_url="https://agents.daedalusdevelopmentgroup.com/v1",    api_key="ddg-x402",    default_headers={"X-Agent-Id": "my-agent"},)

Install

bash
pip install ddg-agent-services-mcp
# With framework support:pip install ddg-agent-services-mcp[langchain]     # or crewai, openai-agents, autogen, etc.pip install ddg-agent-services-mcp[all-frameworks] # everything

Use with any framework

python
from ddg_agent_services_mcp.tools import create_langchain_tools
tools = create_langchain_tools(    agent_id="my-agent",    private_key="0x...",  # Your EVM wallet key (Base USDC))# Pass tools to your LangChain agent

8 frameworks supported: LangChain, CrewAI, OpenAI Agents SDK, AutoGen, PydanticAI, LlamaIndex, Google ADK, and MCP.
