How this service works
Native ETH balance (and live USD value) for any base address.
Output
Returns the native ETH balance held at the specified Base address along with its live USD equivalent value, allowing agents to assess wallet funding and real-time asset worth in a single call.
Example use cases
Pre-payment wallet funding check
“Before I send ETH on Base to 0xabc123..., can you check how much ETH that address already holds and what it's worth in USD right now?”
Portfolio snapshot for a Base wallet
“Give me the native ETH balance and its current USD value for my Base wallet at 0xdef456... so I can see what I'm working with.”
Agent readiness check for autonomous operations
“Does the Base wallet 0x789ghi... have any ETH in it, and if so, how much is it worth in dollars? I need to know if it can cover gas fees.”
Technical details
Endpoint
GEThttps://47620.xyz/x/base/balance/:address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, single-call lookup of the native ETH balance and live USD valuation for a specific Base network address. It is ideal for pre-flight checks before sending transactions, assessing wallet funding, or monitoring agent treasury accounts on Base. Prefer it over stablecoin balance endpoints when you specifically need the native token (ETH), not ERC-20s.
Side effects
- Invalid or malformed Base address returns an error response
- Address not found or never transacted on Base may return a zero balance
- Network congestion or RPC downtime may cause timeouts
- USD price feed unavailability could result in missing or stale USD conversion
- Requests without valid x402 payment header will be rejected
