Checking node health...

Dedicated BSC & Avalanche RPC Nodes

Your own JSON-RPC endpoint, backed by locally-operated archive nodes. No rate-sharing with public RPCs, no cold-start latency, no middleware you don't control.

Authentication

Pass your RPC key in any of two ways

curl -X POST \
  -H "X-API-Key: rpc_YOUR_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
  "https://api.smartmoneyapi.com/rpc/v1/bsc"

Keys are prefixed rpc_ and are separate from your Smart Money API data keys. Keys are shown only once at creation — store them securely.

Examples
Get latest BSC block number
BSC 
curl -X POST \
  -H "X-API-Key: rpc_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
  "https://api.smartmoneyapi.com/rpc/v1/bsc"

// Response: {"jsonrpc":"2.0","result":"0x286c1b2","id":1}
Get AVAX-C wallet balance
AVAX-C 
curl -X POST \
  -H "X-API-Key: rpc_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_getBalance","params":["0xYOUR_ADDRESS","latest"],"id":1}' \
  "https://api.smartmoneyapi.com/rpc/v1/avax-c"
Batch call (up to 50 per request)
PRO 
curl -X POST \
  -H "X-API-Key: rpc_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '[
    {"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1},
    {"jsonrpc":"2.0","method":"eth_gasPrice","params":[],"id":2},
    {"jsonrpc":"2.0","method":"net_version","params":[],"id":3}
  ]' \
  "https://api.smartmoneyapi.com/rpc/v1/bsc"

// Each call in the batch counts toward your quota.
Check Avalanche node bootstrap status
AVAX-INFO 
curl -X POST \
  -H "X-API-Key: rpc_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"info.isBootstrapped","params":{"chain":"C"},"id":1}' \
  "https://api.smartmoneyapi.com/rpc/v1/avax-info"
Node health (public, no key needed)
PUBLIC 
curl "https://api.smartmoneyapi.com/rpc/v1/health"

// Returns: {"chains":{"bsc":{"ok":true,"block":42000000,"ms":45}, ...}}

Why Not Public RPCs?

Dedicated nodes vs shared public endpoints

Feature Public RPC Smart Money RPC
Rate limits Shared, unpredictable Dedicated per key
Latency Variable, cold-start Consistent, warm
Uptime SLA No guarantees Monitored 24/7
Batch calls Often blocked Up to 50 per request
Usage analytics None Per-chain, per-day
