How this service works
Stable edge-hosted x402 utilities for autonomous agents.
Output
A JSON object containing the wallet's ETH balance (as a string), USDC balance (as a string), an array of additional token holdings, and the network identifier ('eip155:8453' for Base mainnet).
Example use cases
Pre-payment balance verification
“Before I send that 50 USDC payment, can you check whether my Base wallet 0xAbC123...def actually has enough USDC to cover it?”
Portfolio snapshot for Base holdings
“Give me a snapshot of all the ETH, USDC, and any other tokens sitting in my Base wallet 0x742d35Cc...4321 right now.”
Autonomous agent treasury check
“My agent needs to know how much ETH is left in its operating wallet 0xDeAdBeEf...9999 on Base before it triggers the next on-chain action.”
Technical details
Endpoint
GEThttps://free-asset-radar-x402.besenok2018.workers.dev/api/x402/base-wallet-balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call balance lookup specifically on Base mainnet (EIP-155 chain 8453) without setting up your own RPC node. It is ideal for autonomous agents that need to verify wallet funds before executing a transaction, for portfolio monitoring bots, or for any workflow requiring real-time on-chain balance data on Base with minimal setup overhead. Prefer alternatives if you need multi-chain balance aggregation or historical balance data.
Side effects
- Invalid or missing wallet address returns empty balances or an error
- Wallet with zero activity returns 0 for ETH and USDC with an empty tokens array
- Network congestion or RPC downtime may cause delayed or failed responses
- Malformed address format results in a request error
- Non-Base EVM addresses return no data as only Base (eip155:8453) is supported
