Lord1Egypt rpc-radar
Inspect, benchmark, and continuously monitor EVM-compatible RPC endpoints. Detects chain ID, measures latency, checks supported methods, and assigns a health score — useful for selecting reliable public RPCs or auditing private node performance.
Quick Scan
# Single endpoint
rpc-radar scan https://eth.llamarpc.com
# Multiple endpoints from file
rpc-radar scan --file endpoints.txt
# Output as JSON
rpc-radar scan https://mainnet.infura.io/v3/KEY --json
What It Checks
| Check | Method | Pass Condition |
|---|---|---|
| Chain ID | eth_chainId |
Returns expected chain |
| Block height | eth_blockNumber |
Non-zero, synced |
| Latency | timed request | < 500ms = good |
| Batch support | batch JSON-RPC | Response array |
| Archive depth | eth_getBalance (old block) |
Returns value |
| Filter support | eth_newFilter |
No error |
| WebSocket | ws:// upgrade | Handshake success |
Benchmark Mode
# 100 requests, measure p50/p95/p99
rpc-radar bench https://eth.llamarpc.com --requests 100
# Compare two endpoints
rpc-radar compare https://eth.llamarpc.com https://rpc.ankr.com/eth
Monitor Mode (continuous)
# Poll every 30s, alert if latency > 1000ms or block falls behind
rpc-radar monitor https://eth.llamarpc.com --interval 30 --alert-latency 1000
# Monitor multiple and export to CSV
rpc-radar monitor --file endpoints.txt --output monitor.csv
Health Score
Each endpoint gets a 0–100 score:
- Latency (40 pts): < 200ms = 40, < 500ms = 20, > 500ms = 0
- Uptime (30 pts): based on consecutive successful checks
- Block sync (20 pts): within 2 blocks of best known
- Method support (10 pts): supports batch + filters + archive
Supported Chains
Auto-detected by chain ID: Ethereum, Polygon, BSC, Arbitrum, Optimism, Avalanche, Base, Fantom, and any other EVM-compatible chain.
