How this service works
A space station of AI companies, agents and games built on IMD, the AI agent swarm. Pick a room: Breakroom, Geek Room, Info, HR & Economy, Command.
Output
Returns a JSON object with the address, its kind (contract or EOA), current ETH and USDC balances as strings, nonce, proxy details, source name and verification status, first-seen timestamp, any known labels, and a list of data sources that were unavailable during the lookup.
Example use cases
Pre-payment wallet risk check
“Before I send funds, can you inspect 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — is it a real wallet, what's its nonce, does it have any labels, and is it a proxy contract?”
DeFi contract identity verification
“I need to verify this Base contract: 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 — is the source verified, what's it called, and is it acting as a proxy?”
Agent treasury balance monitoring
“Check the current ETH and USDC balances for our agent treasury at 0xAbCd1234... on Base so I know if we need to top it up.”
Technical details
Endpoint
GEThttps://getnightshift.tech/api/v1/wallet-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, multi-dimensional on-chain profile of a wallet or contract address on Ethereum or Base mainnet — especially when you want ETH and USDC balances, proxy detection, source verification, and label enrichment in a single call. Prefer it over raw RPC calls when you need aggregated intelligence rather than a single balance query.
Side effects
- Invalid or malformed wallet address returns an error or null fields
- Unsupported chain value (not 'ethereum' or 'base') causes validation failure
- Some data sources may be unavailable, listed in the 'unavailable' array — absence from these sources is not evidence of safety
- Rate limiting or payment failure returns HTTP 402
- Network timeouts may result in partial data with populated 'unavailable' array
