How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
Output
A JSON response containing the list of tokens held by the specified Ethereum address, including token names, contract addresses, balances, and potentially decimal/symbol metadata for each ERC-20 token in the wallet.
Example use cases
DeFi portfolio token audit
“Can you pull all the tokens held by the Ethereum wallet 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe on the ETH network? I want to see exactly what ERC-20s are in there.”
On-chain wallet due diligence
“Before I send funds, check what tokens the Ethereum address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B is holding on ETH — I want to know if it looks like a normal wallet or something suspicious.”
Automated token balance monitoring
“Every hour, check what tokens are in the Ethereum address 0x8f3Cf7ad23Cd3CaDbD9735AFt5955576CDB8dEBD on ETH and alert me if any new ERC-20 tokens appear that weren't there before.”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/eth/address/tokens?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-chain token holdings specifically for Ethereum addresses and want a single-call lookup via a reputable blockchain explorer (blockchain.com) rather than running your own node query or using a generic multi-chain API that may have lower data freshness. Particularly useful when building portfolio dashboards, wallet auditing tools, or compliance checks that need ERC-20 token enumeration for a given address.
Side effects
- Invalid or malformed Ethereum address returns an error or empty result
- Unsupported network value causes a bad request response
- Address with no token holdings returns an empty token array
- Rate limiting or payment failure (x402) blocks the request
- Newly minted or very obscure tokens may not appear if not indexed
