Send us a JSON-RPC call, get blockchain data back. That's it.\n\n---\n\n## What You Can Do\n\n**V1 -- Query the blockchain** (Free to start)\nGet block data, check balances, send transactions. Standard JSON-RPC, nothing extra.\n```\ncurl -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```\n\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.\n```\ncurl -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```\n\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.\n\n---\n\n## 60-Second Setup\n\n1. Go to [nodemasterx.com/login](https://nodemasterx.com/login) and sign in with GitHub\n2. Copy your token from the dashboard\n3. Set the `token` variable in this collection to your token\n4. Open **Getting Started** > **Check Account Status** and hit Send\n5. If it returns your account info, you're in. Start making calls.\n\nFor V1 calls, that's all you need. For V2/V3, you'll need to top up credits first (see Getting Started).\n\n---\n\n## Pricing\n\n| | V1 | V2 | V3 |\n|---|---|---|---|\n| **What** | Raw RPC | RPC + Rules Engine | RPC + AI Agent |\n| **Free tier** | First 10K requests | No free tier | No free tier |\n| **Cost** | $0.00001/req after free tier | $0.10 setup + $0.10/day + token costs | $20/month + per-feature |\n| **Setup** | Nothing. Just call it. | Top up credits, register an interface | Subscribe, create an agent |\n\n---\n\n## Support\n\nNo chatbots.
