NodeMasterX API

We run blockchain nodes (Polygon, Bitcoin) so you don't have to. Send us a JSON-RPC call, get blockchain data back. That's it.

What You Can Do

V1 -- Query the blockchain (Free to start)\nGet block data, check balances, send transactions. Standard JSON-RPC, nothing extra.

curl -X POST https://nodemasterx.com/v1/polygon-mainnet \\\n  -H \"Authorization: Bearer YOUR_TOKEN\" \\\n  -d '{\"jsonrpc\":\"2.0\",\"method\":\"eth_blockNumber\",\"params\":[],\"id\":1}'\n

V2 -- Add security rules to your calls (Pre-paid credits)\nDefine rules like \"block any transaction over $10k\" or \"reject calls to unverified contracts\". Every RPC call passes through your rules before hitting the chain.

curl -X POST https://nodemasterx.com/v2/polygon-mainnet \\\n  -H \"Authorization: Bearer YOUR_TOKEN\" \\\n  -H \"x-interface-id: YOUR_INTERFACE_ID\" \\\n  -d '{\"jsonrpc\":\"2.0\",\"method\":\"eth_sendRawTransaction\",\"params\":[\"0xf86...\"],\"id\":1}'\n

V3 -- AI agent analyzes every transaction ($20/month)\nAn AI agent checks contracts, detects MEV attacks, verifies wallet history, and decides PASS/BLOCK/FLAG -- with full reasoning. It can call tools (verify contracts on Etherscan, check balances, simulate the tx) before making a decision.

60-Second Setup

Go to nodemasterx.com/login and sign in with GitHub
Copy your token from the dashboard
Set the token variable in this collection to your token
Open Getting Started > Check Account Status and hit Send
If it returns your account info, you're in. Start making calls.

For V1 calls, that's all you need. For V2/V3, you'll need to top up credits first (see Getting Started).

How it works:

Set the credits value in the body (minimum 5, which is $5 USD)
Hit Send
You'll get back a Stripe Checkout URL
Open that URL in your browser, pay, and credits are added to your account

What gets charged against credits:

V2 interface creation: $0.10 one-time

Getting Started

Your first stop. Run these requests to set up your account.

1. Get your token

Go to nodemasterx.com/login, sign in with GitHub, and copy your Bearer token. Paste it into the token collection variable (top right > Variables).

2. Check your account

Run Check Account Status below. If you get back your billing info, your token works.

3. Using V1 (free)?

You're done. Go to Polygon Mainnet (V1) or Bitcoin Mainnet (V1) and start making calls. Your first 10,000 requests are free.

4. Using V2 or V3?

You need credits first. Run Top Up Account below (minimum $5). This opens a Stripe checkout page where you buy credits.

Once you have credits:

V2: Go to Intelligence Layer (V2) > Management > Register Interface to create your rules
V3: Go to Agentic System (V3) > Subscription Management > Subscribe to V3, then create an agent

Bitcoin Mainnet (V1) -- Direct RPC

Standard Bitcoin Core JSON-RPC calls against Bitcoin mainnet.

No interface, no rules, no AI -- just your call going straight to the node.

Endpoint: POST https://nodemasterx.com/v1/bitcoin-mainnet

Auth: Authorization: Bearer YOUR_TOKEN

Free tier: First 10,000 requests cost nothing. After that, $0.00001 per request.

Every request below is a working example.

Common use cases:

Get the current block height (getblockcount)
Look up a block by hash (getblock)
Check mempool state (getrawmempool)
Decode or broadcast a raw transaction (decoderawtransaction, sendrawtransaction)
Estimate fees (estimatesmartfee)

Intelligence Layer (V2)

V2 adds a rules engine between your app and the blockchain.

You define an \"interface\" -- a set of rules like:

\"Block any transaction worth more than $10,000\"
\"Reject calls to unverified contracts\"
\"If gas price is above 150 gwei, don't send\"

Then you route your RPC calls through that interface. NMX checks every call against your rules and either passes it through or blocks it.

How to Use V2 (Step by Step)

Step 1: Top up credits

Go to Getting Started > Top Up Account. Minimum $5.

Step 2: Register an interface

Go to Management > Register Interface below. Define your rules in the request body (see Use Cases folder for ready-made examples). You'll get back an interface_id.

Step 3: Make calls through your interface

Go to RPC (AI-Powered) below. Pick your network (Polygon or Bitcoin). Add the x-interface-id header with your ID. Hit Send.

The response includes X-NMX-Decision headers showing whether your call was PASSED, BLOCKED, or FLAGGED, and why.

Step 4: Managing interfaces

Interfaces are immutable -- you can't edit them. If you need to change your rules, delete the old interface (stops billing) and register a new one.

What It Costs

Creating an interface: $0.10 (one-time)
Keeping it active: $0.10/day
Per-request token costs: varies
Delete the interface to stop all charges

Agent with a custom HTTP tool that calls your internal risk scoring API.

Extend the agent with your own APIs.

Example: the agent calls your internal risk-scoring API to check an address before deciding whether to allow the transaction. You define the HTTP endpoint, parameters, and headers -- the agent calls it like any other tool.

Agentic System (V3)

V3 replaces static rules (V2) with an AI agent that thinks about each transaction.

Instead of \"block if value > $10k\", you write:\n\"You are a security agent. Check if the target contract is verified. If it's less than 24 hours old, block it. If it looks like a drainer, block it. Otherwise, pass it through.\"

The agent reads your instruction, calls blockchain tools to gather data (check contract verification, detect MEV, check wallet balances), and decides PASS / BLOCK / FLAG with a written explanation.

How to Use V3 (Step by Step)

\n\n

Go to Subscription Management > Subscribe to V3 ($20/month).

Step 2: Create an agent

Go to Interface Management > Create V3 Agent Interface.\nDefine your system prompt (what the agent should do), pick your model, and enable the tools you want.\nYou'll get back an interface_id.

Step 3: Route your RPC calls

Send transactions to POST /v3/{network} with the X-NMX-Interface-ID header.\nThe agent analyzes each call and returns its decision.

Step 4 (optional): Add webhooks

Step 5 (optional): Review decisions

Check Audit Logs to see every decision the agent has made, including full reasoning.

Tool	What It Does
`nmx_check_contract_verified`	Is this contract verified on Etherscan?
`nmx_get_contract_creation`	When was this contract deployed? (Block if < 24h)
`nmx_get_native_balance`	How much ETH/MATIC does this wallet hold?
`nmx_check_token_holdings`	What tokens does this wallet hold?
`nmx_get_nonce`	How many transactions has this wallet sent?
`nmx_detect_mev`	Is this transaction being sandwich attacked?

You can also add your own custom HTTP tools (see Use Case Templates > Custom HTTP Tools).
