How this service works
Pay-per-call tools for AI agents: web page text extraction and summaries, screenshots, image generation, speech-to-text, image description, domain and email-auth intelligence, and live Base token and wallet lookups. No account or API key; pay per request in USDC on Base via x402.
Output
A JSON object containing the ETH balance in both raw wei and human-readable format, the account type (wallet or contract), the Base chain identifier, the transaction count, and an array of ERC-20 token balances each with symbol, contract address, raw balance, decimals, and formatted balance.
Example use cases
DeFi portfolio balance check
“What's the current ETH balance and all token holdings for Base wallet 0xAbC123...def456? I also want to know if it's a smart contract or an EOA.”
Pre-payment wallet verification
“Before I send funds, can you verify how much ETH and USDC the Base address 0x1234567890abcdef1234567890abcdef12345678 currently holds?”
Token-specific balance audit
“Check the USDC and DAI balances on Base for address 0xDeadBeef00000000000000000000000000000001 — I need the exact formatted amounts.”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/wallet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-account-required lookup of ETH and ERC-20 token balances on the Base network for any wallet or contract address. It is ideal for AI agents that need on-chain balance data without setting up a full node or managing API keys — paying only $0.005 USDC per call via x402. Prefer it over generic blockchain explorers when you want structured JSON output ready for downstream processing.
Side effects
- Invalid or malformed address returns an error
- Address not found on Base returns empty or zero balances
- Requesting more than 20 extra ERC-20 tokens in one call may be rejected
- Payment failure (insufficient USDC or x402 protocol error) blocks the request
- Network or provider downtime results in timeout or 5xx error
