AMR

Integrations

Drop AMR into the stack you already run

Agent Margin Router is one HTTP API with 50 data endpoints. Connect it to your MCP client, your n8n workflows, your Open WebUI, LangChain or raw code — whatever your agents already speak. You keep hosting your side; every call is metered per request, three free per wallet.

See pricingAPI docs

You host it, you own it

AMR plugs into the n8n, Open WebUI or agent runtime you already run. Nothing to deploy on our side, no infrastructure to manage on yours.

Three calls free per wallet

Every integration starts on the free tier — no signup, no key. Pass an EVM wallet address and make your first calls at zero cost.

One API, every framework

The same 50 endpoints show up as MCP tools, an n8n node, an OpenAPI tool server or typed SDK methods. Pick the surface your stack speaks.

Model Context Protocol

MCP server — Claude, Cursor, Cline, any MCP client

AMR ships a remote MCP server over Streamable HTTP. Point your MCP client at one URL and all paid endpoints appear as callable tools. Payment is handled inside the protocol: pass a wallet for the free tier, an API key, or a signed x402 payload to keep going.

      "type": "streamable-http",
      "url": "https://agent-margin-router-production.up.railway.app/mcp"
    }
  }
}

Add the block to your client's MCP config (e.g. Claude Desktop's claude_desktop_config.json), restart, and the tools list themselves. Discovery manifests live at /.well-known/mcp.json.

n8n

n8n community node — add AMR to any workflow

Run your own n8n instance? Install the community node and every endpoint becomes a drag-and-drop step. No code, no custom HTTP nodes to wire up — pick the operation, pass your wallet, connect it to the rest of your flow.

Open WebUI

Open WebUI — register AMR as an OpenAPI tool server

Open WebUI can import any OpenAPI tool server. AMR publishes a full OpenAPI schema, so your local models get live market data, on-chain lookups and web extraction as tools — without writing a single function.

https://agent-margin-router-production.up.railway.app/openapi.json

In Open WebUI go to Settings → Tools → Add Tool Server, paste the URL above, and add X-WALLET as a header for the free tier. The endpoints appear as tools your models can call.

LangChain

LangChain toolkit — typed tools for your agents

Building with LangChain? The dedicated package turns every endpoint into a LangChain tool with proper schemas, ready to hand to any agent executor.

pip installTyped toolsAgent-ready
langchain_setup.py
pip install langchain-agent-margin-router

# Add all 50 endpoints as LangChain tools
from langchain_agent_margin_router import AgentMarginRouterToolkit

toolkit = AgentMarginRouterToolkit(wallet="0xYourAgentWallet")
tools = toolkit.get_tools()   # hand these to any LangChain agent

Python SDK

Python SDK — one typed method per endpoint

Prefer plain Python? The official SDK gives you one typed method per endpoint, a single dependency and optional auto-payment for HTTP 402 responses.

Anything else

Plain HTTP — works with every language and runtime

No framework required. Every endpoint is a normal JSON POST. Send your wallet in the X-WALLET header for the free tier; when it runs out you get a standard HTTP 402 with exactly what to pay.

Pick your surface and make a free call

Same data, same price, whichever way you connect. Start on the free tier, then pay per request — no subscription, no minimum.
