How this service works
Native + USDC + custom-token balances for any wallet on Base, Ethereum, or Solana — with USD estimates — straight from public RPCs, no API key. Raw units as decimal strings plus formatted numbers; add up to 10 ERC-20 contracts via tokens=. 60s cache; an empty, never-used address is a real answer (zeros + no_activity_detected finding).
Output
A JSON object containing the queried wallet address and chain, native token balance (raw wei/lamports as decimal string, formatted number, symbol, and USD estimate), USDC balance (raw, formatted, USD), an array of any additional token balances requested (address, symbol, raw, formatted, USD), findings array (e.g. no_activity_detected for empty wallets), cache age in seconds, a stale flag, and the RPC source that answered.
Example use cases
DeFi portfolio snapshot
“Show me all balances — native token, USDC, and the USDT contract 0xdAC17F958D2ee523a2206206994597C13D831ec7 — for Ethereum wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B with USD values.”
Solana wallet audit
“Check the SOL and USDC balances for Solana wallet 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM and tell me if there's any activity on it.”
Inactive address detection
“I want to verify if the Base wallet 0x1234567890abcdef1234567890abcdef12345678 has ever been used — check its native and USDC balances and flag it if it looks empty or inactive.”
Technical details
Endpoint
GEThttps://netintel.dev/wallet/balanceWhen to prefer
Choose this endpoint when you need multi-asset wallet balances (native + USDC + arbitrary ERC-20s) across Base, Ethereum, or Solana in a single call without managing your own RPC infrastructure or API keys. It is especially useful when you need both raw on-chain units and human-readable formatted numbers with USD estimates simultaneously. Prefer it over blockchain explorer APIs when you want zero-configuration access and don't mind a 60-second cache. Not suited for historical balance lookups, transaction history, or NFT holdings.
Side effects
- Invalid wallet address format returns an error (must be 0x+40 hex for EVM or base58 for Solana)
- Unsupported chain name returns an error (only base, ethereum, solana accepted)
- More than 10 ERC-20 addresses in tokens= parameter causes a validation error
- USD price estimate may be null if price feed is unavailable for a token
- Stale flag set to true if cached data is near or at the 60-second TTL boundary
- Invalid ERC-20 contract address in tokens= may return null values for that token
