How this service works
Cross-chain Token Balance
Output
Returns token balance data for the specified wallet address broken down by each requested chain, showing how much of the given token (e.g. USDC) is held on each blockchain network.
Example use cases
DeFi portfolio cross-chain audit
“Can you pull the USDC balance for wallet 0x1234...abcd across Ethereum, Polygon, and Base so I can see where my liquidity is spread?”
Automated treasury reconciliation
“Check our company wallet 0xDEAD...BEEF for USDC balances on Ethereum and Arbitrum — I need the numbers for our weekly treasury report.”
On-chain eligibility check
“I need to verify whether wallet 0xAAAA...BBBB holds at least any ETH on Optimism or Base before I approve their access.”
Technical details
Endpoint
POSThttps://x402.agentfund.net/x402/onchain_cross_chain_balancesWhen to prefer
Choose this endpoint when you need to aggregate a single token's balance across multiple blockchains for one wallet address in a single call, rather than querying each chain's RPC individually. Ideal for DeFi dashboards, treasury management agents, and eligibility checks where cross-chain visibility matters. Prefer the sibling 'On-chain Portfolio (USD-valued)' endpoint if you want USD-valued multi-asset portfolio data instead of raw token balances.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain name in the chains array may be silently ignored or return an error
- Token symbol not recognized may default to USDC or return an error
- Network latency or RPC node issues may cause incomplete chain coverage
- Payment failure (HTTP 402) if USDC payment is not properly attached
