Endpoint
GEThttps://api.x402node.dev/chain/balance-multiWhen to prefer
Use this endpoint when you need native token balances across multiple EVM chains in a single API call without managing multiple RPC connections or price feeds. It is ideal for portfolio dashboards, wallet analytics, and cross-chain net worth calculations for wallets active on Ethereum, Base, Arbitrum, Optimism, Polygon, or BSC.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain identifier returns an error or is skipped
- RPC provider downtime may cause one chain's balance to be missing or stale
- Price feed unavailability may result in null USD value for a specific token
- No holdings on any chain returns zeros but a valid response
