How this service works

Get the native token balance for any wallet address and a list of recently interacted ERC-20 tokens. Supports Ethereum and other EVM chains via Etherscan V2.

Output

Returns the native token balance (e.g. ETH in wei or formatted units) for the queried wallet address on the specified EVM chain, along with a list of ERC-20 tokens the wallet has recently interacted with, including token metadata. Chain ID and address are echoed back in the response.

Example use cases

Example prompt

“What's the ETH balance and recent ERC-20 token activity for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum mainnet (chain ID 1)?”

Technical details

Endpoint

GEThttps://api.strale.io/x402/wallet-balance-lookup

When to prefer

Use this endpoint when you need to quickly check the on-chain native token balance and recent ERC-20 token interactions for any EVM-compatible wallet address, especially on Ethereum mainnet. Prefer this over block explorer UIs or full node queries when you need a lightweight, pay-per-call programmatic lookup without managing API keys or Etherscan subscriptions directly.

Side effects

Invalid or malformed wallet address returns an error
Unsupported chain ID returns an error or empty result
Etherscan V2 rate limit or downtime causes upstream failure
Payment not provided or insufficient USDC causes 402 Payment Required response
Address with no transaction history may return empty token list
