How this service works
Tiny pay-per-call utilities for agents on Base: wallet vetting, x402 endpoint linting, deterministic entity extraction.
Output
A JSON object containing: the wallet address, chain ID (8453 for Base), ETH balance (string), USDC balance (string), total transaction count (integer), a boolean indicating whether the address is a smart contract, and the count of ERC-8004 identity records associated with the wallet.
Example use cases
Pre-payment wallet due diligence
“Before I send 50 USDC to 0xAbCd1234...5678 on Base, can you check their wallet — how active is it, what balances does it have, and is it even a real user wallet and not a contract?”
Detect bot or contract counterparty
“I'm about to interact with address 0x9f8e7d6c...1a2b on Base — can you tell me if it's a smart contract or a regular account, and how many transactions it's done?”
On-chain identity verification for airdrop
“I need to filter airdrop recipients — can you pull the wallet profile for 0x1111222233334444555566667777888899990000 on Base and tell me if it has any ERC-8004 identities and whether it looks like a real, active wallet?”
Technical details
Endpoint
GEThttps://mm-agent-utils.gferrigno.deno.net/v1/wallet-profile?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call wallet profile specifically on the Base (chain ID 8453) network, especially when vetting counterparties before transactions, filtering airdrop recipients, or checking for ERC-8004 identity signals. Prefer it over general block explorers when you need structured JSON output in an agent workflow without scraping HTML. It is purpose-built for agent use cases via x402 micropayments, making it suitable for automated pipelines.
Side effects
- Invalid or malformed 0x address returns a validation error
- Address not found on Base returns zero balances and zero tx_count
- Network or RPC timeout results in a 5xx error
- Missing required 'address' query parameter returns a 400 bad request
- Non-Base chain addresses may return misleading or empty data since only chain_id 8453 is supported
