Integrations
Wiring evmquery into the stack you already run: agent frameworks like LangChain, LangGraph, CrewAI and the Vercel AI SDK, plus MCP clients and n8n workflows. Each one ends with a working tool call.
Wallet Balance Change Alerts in n8n: Telegram Notifications With Zero Code
Get a Telegram alert the moment a wallet's USDT or USDC balance changes, using n8n's evmquery trigger node. No Schedule Trigger, no IF node, no state store.
evmquery in Any AI Agent Framework: The Complete Integration Matrix
One-page reference for wiring evmquery's onchain reads into 21 AI agent frameworks, from LangChain to Semantic Kernel. Install command and tool pattern per framework.
Live On-Chain Data in LangGraph: Build an EVM Blockchain Tool in 40 Lines
Wire evmquery into a LangGraph ReAct agent to query live EVM contract data — token supplies, oracle prices, DeFi positions — with full state persistence across tool calls. No ABIs, no RPC node.
Live Onchain Data in Pydantic AI: Build an EVM Blockchain Tool in 30 Lines
Define a typed Pydantic AI tool that reads live EVM contract data — USDC balances, ETH prices, Aave positions — without ABIs, RPC nodes, or web3.py boilerplate.
Live Onchain Data in CrewAI: Build a Custom EVM Blockchain Tool
Wire a custom evmquery tool into CrewAI and give your AI crew live access to EVM contract state — USDC balances, ETH prices, and Aave health factors — without ABIs or RPC nodes.
