How this service works

40 pay-per-request AI, search, headless browser, crypto alpha & memory APIs for autonomous agents settling in USDC on Base via x402 v2.

Output

A JSON object containing the wallet's ETH balance and USDC balance as decimal strings (e.g. ethBalance: '0.15', usdcBalance: '250.00'), along with a success status and the endpoint path.

Example use cases

Pre-transaction balance check

“Before I send that payment, can you check if wallet 0xABC123...def456 has enough USDC on mainnet to cover it?”

Agent treasury monitoring

“What are the current ETH and USDC balances for my agent's treasury wallet 0x1234abcd...5678ef on mainnet?”

Testnet wallet verification

“Check the ETH and USDC balances on Sepolia testnet for wallet address 0xDEAD...BEEF so I can confirm my test funds arrived.”

Endpoint

GEThttps://api.molcloud.net/api/crypto/wallet?utm_source=zero.xyz

When to prefer

Choose this endpoint when an AI agent needs to quickly look up on-chain ETH and USDC balances for any EVM-compatible wallet address on Ethereum mainnet or Sepolia testnet, especially within a pay-per-request x402 micropayment workflow. Prefer this over block explorer scraping or running a full node query when lightweight, low-cost, agent-native balance lookups are needed.

Side effects

Invalid or malformed wallet address (non-0x format) returns an error
Unsupported network value returns a validation error
Network RPC unavailable or timeout may cause a failed lookup
Address not found on specified network returns zero balances
Payment of $0.005 USDC not settled via x402 results in 402 response
