Example use cases
Verify wallet funds before DeFi action
“Before I swap anything, can you check the current ETH and USDC balance of 0xAbC123...def456 on Base so I know what I'm working with?”
Monitor recipient wallet balance
“I'm about to send USDC to 0x9F8a7b6c5D4E3f2A1B0c9D8e7F6a5B4c3D2e1F0 — can you first check how much ETH and USDC that address already has on Base?”
Audit agent treasury address
“Check the live ETH and USDC balance on Base for our treasury wallet at 0x1234567890abcdef1234567890abcdef12345678 and tell me what's currently there.”

Endpoint
POSThttps://amanchain-relay.gitajhd.workers.dev/api/x402/aman-evm-balanceWhen to prefer
Use this endpoint when you need a quick, no-account, pay-per-call lookup of both native ETH and USDC balances for any Base wallet address simultaneously. Prefer it over general-purpose RPC calls when you want a managed, metered service with no API key setup and guaranteed live consensus state. Best suited for agents that need on-demand balance checks without maintaining blockchain node infrastructure.
Side effects
- Invalid or malformed EVM address returns an error
- Address with zero activity may return zero balances (not an error)
- Network congestion or node unavailability may cause timeouts
- Payment failure via x402 will block the call from executing
- Wrong serviceId in body causes routing error
