Pay-per-call x402 gateway for AI agents — MCP server + OpenAI-compatible API for agent tools, market data, RPC, and MCP
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.
124 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).
https://agents.daedalusdevelopmentgroup.com
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:
export DDG_AGENT_ID="my-agent"
export DDG_PRIVATE_KEY="0x..."
from ddg_agent_services_mcp import ddg
client = ddg() # reads from env
Drop-in replacement for openai-python — point any OpenAI client at DDG:
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:
from openai import OpenAI
client = OpenAI(
base_url="https://agents.daedalusdevelopmentgroup.com/v1",
api_key="ddg-x402",
default_headers={"X-Agent-Id": "my-agent"},
)
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
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.
