How this service works
Base address -> agent-ready on-chain profile: EOA or contract, ETH and major-token holdings, token or NFT metadata, EIP-1967 proxy detection, activity, and a derived profile label. Uses public Base mainnet RPC with no account or API key. Useful before an agent sends funds, swaps, or calls a contract.
Output
Returns a structured on-chain profile for the given Base address including: EOA vs contract classification, ETH and major token balances, token and NFT metadata, EIP-1967 proxy detection result, recent activity indicators, and a derived human-readable profile label — all sourced from public Base mainnet RPC with no API key required.
Example use cases
Pre-transfer wallet vetting
“I'm about to send 500 USDC to 0x4200000000000000000000000000000000000006 on Base — can you check its on-chain profile first, including whether it's a contract or regular wallet, what tokens it holds, and give me a risk label?”
DeFi contract inspection before interaction
“I want to call into 0x2626664c2603336E57B271c5C0b26F421741e481 on Base for a swap — can you check if it's an EIP-1967 proxy, what its activity looks like, and give me an agent-ready profile before I interact with it?”
NFT holder research
“Can you pull the on-chain profile for Base address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and tell me what NFTs and major tokens it holds, plus its activity level?”
Technical details
Endpoint
GEThttps://agents.samedaydesk.com/wallet-enrichWhen to prefer
Use this endpoint when an AI agent needs to pre-screen a Base mainnet address before sending funds, executing a swap, or calling a contract. It is uniquely suited for Base chain, requires no API key, covers EOA/contract distinction and proxy detection in a single call, and is priced per-use via x402 micropayment — ideal for automated agent workflows that need safe, lightweight wallet intelligence without managing credentials.
Side effects
- Invalid address format (not 0x + 40 hex) returns an error
- Address not found or zero-activity wallet may return sparse data
- Base RPC rate limits or downtime may cause timeout or partial data
- Non-Base EVM addresses (e.g. Ethereum mainnet) may return no or incorrect data
- Malformed query parameter returns schema validation error
