n8n Community Node
Use Crypto APIs in n8n Workflows
The Crypto APIs community node (@cryptoapis-io/n8n-nodes-cryptoapis) brings blockchain data and operations directly into n8n — no MCP servers or extra infrastructure required. It calls the Crypto APIs REST API natively and works both as a standard workflow node and as an AI Agent tool.
Installation
- In n8n, go to Settings > Community Nodes
- Search for
@cryptoapis-io/n8n-nodes-cryptoapisand install it - Set up the Crypto APIs API credential with your API key from app.cryptoapis.io
The node appears as Crypto APIs in the node palette and is ready to use.
What You Can Do
The node exposes 13 resources covering the full Crypto APIs platform across 20+ blockchains:
| Resource | What it does |
|---|---|
| Address Latest | Get current balances, nonces, token holdings, and recent transactions for EVM, UTXO, Solana, XRP, and Kaspa addresses |
| Address History | Sync addresses and retrieve full transaction and token transfer history (EVM, UTXO) |
| Block Data | Fetch blocks by height or hash, list block transactions, get the latest mined block (EVM, UTXO, XRP) |
| Blockchain Fees | Get fee recommendations, EIP-1559 estimates, and gas estimation for transfers and contract calls (EVM, UTXO, XRP) |
| Transactions Data | Look up transaction details, internal transactions, token transfers, and logs (EVM, UTXO, Solana, XRP, Kaspa) |
| Market Data | Get asset details, exchange rates, and list supported assets |
| HD Wallet | Sync HD wallets, derive addresses, list balances and transactions (EVM, UTXO, XRP) |
| Prepare Transactions | Build unsigned EVM transactions — native coin, ERC-20, and ERC-721 transfers |
| Simulate | Dry-run an EVM transaction before broadcasting |
| Broadcast | Submit signed raw transactions to the network (EVM, UTXO) |
| Blockchain Events | Create and manage webhook subscriptions for on-chain events — confirmed/unconfirmed coins, tokens, new blocks, and more |
| Contracts | Get token details by contract address (EVM, Solana) |
| Utils | Validate addresses, decode raw transactions, derive addresses from xPub, encode/decode XRP X-Addresses |
Using It as a Standard Node
Drag the Crypto APIs node into any workflow and configure:
- Resource — pick from the 13 categories above
- Blockchain type — EVM, UTXO, Solana, XRP, or Kaspa (depending on the resource)
- Operation — the specific action (e.g., Get Balance, List Transactions)
- Parameters — blockchain, network, address, etc.
Pagination is handled automatically — toggle Return All to fetch every result, or set a limit.
Using It as an AI Agent Tool
The node has usableAsTool enabled, so it plugs directly into n8n's AI Agent node:
- Add an AI Agent node to your workflow
- Under Tools, click + Tool and select Crypto APIs
- Configure the resource and operation
- The AI agent can now call this tool autonomously based on user prompts
This approach gives the AI agent structured access to specific blockchain operations without needing to run separate MCP servers.
Example Workflow Ideas
- Portfolio dashboard — Trigger on a schedule, use Address Latest to fetch balances across multiple wallets, aggregate with a Code node, and push to a Google Sheet or dashboard.
- Whale alert bot — Use Blockchain Events to subscribe to large incoming transfers on a watched address, then post alerts to Slack or Telegram.
- Gas price monitor — Run Blockchain Fees every few minutes, compare against a threshold in an If node, and send a notification when gas is cheap.
- Payment processor — Receive a webhook, use Prepare Transactions to build a payout, sign it externally, then Broadcast the result — all in one workflow.
- Token analytics — Use Market Data to pull exchange rates and Contracts to get token details, then combine and store in a database for reporting.
Supported Blockchains
EVM: Ethereum, Ethereum Classic, Binance Smart Chain, Polygon, Avalanche C-Chain, Tron, Arbitrum, Base, Optimism UTXO: Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash Other: XRP, Solana, Kaspa
Each blockchain supports mainnet and testnet (where available).
Notes
- The node calls the Crypto APIs REST API directly — no MCP servers or additional services are needed.
- API key is the only credential required. Get one at cryptoapis.io.
- For the MCP-based approach (connecting to Crypto APIs MCP servers via n8n's MCP Client Tool), see the separate MCP integration guide.
