How this service works
All token balances for any address in one call, from Coinbase's indexed data API - ERC-20 + native on EVM, SPL on Solana; no per-token contract calls, no RPC wrangling. Networks: base, ethereum, base-sepolia, solana, solana-devnet. Symbols/decimals populated for whitelisted tokens (USDC always included).
Output
A list of all token balances held by the specified wallet address on the given network, including token symbols, decimal-adjusted amounts, and both ERC-20/native tokens (EVM) or SPL tokens (Solana) — no need to call individual token contracts.
Example use cases
Example prompt
“What tokens does wallet 0x742d35Cc6634C0532925a3b8D4C9B7e8f2d4A1b9 hold on Base — show me all balances including ERC-20s and the native ETH?”
Technical details
Endpoint
GEThttps://agent402.tools/api/wallet-balancesWhen to prefer
Use this endpoint when you need all token balances for a wallet in a single call without RPC node access or per-token contract calls. Ideal for portfolio aggregation, balance checks across EVM chains (Base, Ethereum, Base Sepolia) and Solana, leveraging Coinbase-indexed data for reliability and speed. Prefer this over direct RPC calls when simplicity, cost-effectiveness ($0.002/call), and multi-token aggregation matter.
Side effects
- Invalid or malformed wallet address returns an error
- Address format mismatch (e.g. EVM address on Solana network) causes failure
- Unsupported network name returns an error
- Rate limiting or payment failure (402) if x402 payment not properly handled
- Network-specific downtime may cause intermittent failures
