How this service works
Use before interacting with an unfamiliar Base (chain 8453) address: returns a public-data red-flag snapshot (contract vs EOA, EIP-7702 delegation, source verification, upgradeable proxy, age, activity, ETH/USDC balance, risk level). Pass ?address=0x... Errors: 400 invalid address. Informational only.
Output
A JSON object containing: the address, chainId (8453), accountType (contract/eoa/eoa_eip7702_delegated), risk level (low/medium/high/unknown), whether source code is verified, proxy details (standard, upgradeable, admin, implementation), whether it is EIP-7702 delegated, address age in days, firstSeenAt timestamp, sentTxCount, ETH and USDC balances, and an array of risk flags each with a code, severity level, and detail string.
Example use cases
DeFi contract safety check before approval
“I'm about to approve a token spend on Base contract 0x2ce6311ddae708829bc0784c967b7d77d19fd779 — can you check if it's verified, whether it's an upgradeable proxy, and what the risk level is before I proceed?”
Screening an unknown wallet before sending crypto
“Someone just sent me a payment request from 0x4fc7850364958d97b4d3f5a08f79db2493f8ca44 on Base — can you check if it looks legitimate, how old the address is, and whether there are any red flags?”
EIP-7702 delegation detection for a Base address
“Can you check if 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base has been delegated via EIP-7702 and give me a full risk snapshot including its account type and activity history?”
Technical details
Endpoint
GEThttps://x402-research-iota.vercel.app/api/firm/risk-snapshot?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a fast, pre-interaction due-diligence check on an unfamiliar Base (chain 8453) address — especially before approving token transfers, interacting with a DeFi protocol, or sending funds. It is purpose-built for Base and returns a uniquely structured risk snapshot combining on-chain metadata (proxy type, verification, EIP-7702 status, age, balances) into a single call. Prefer over generic block explorer lookups when you need a machine-readable risk level and structured flags rather than raw chain data.
Side effects
- 400 Bad Request — invalid or malformed address parameter (e.g. missing 0x prefix, wrong length)
- Missing ?address= query parameter returns error
- Address not found on Base chain may return unknown risk level or limited data
- Network or provider outage may delay or fail response
- Non-Base chain addresses will not return meaningful results (Base/chain 8453 only)
