How this service works
Address intelligence on Base — EOA/contract/ERC-20 + nonce + ETH/USDC balance + keyless GoPlus security verdict (phishing/sanctioned/mixer/…). The loop input for triaging a counterparty. Pay-per-call via x402. An empty body is answered for the wallet that pays (the payment's signer); send {"address":"0x…"} for any other address.
Output
A JSON object containing: timestamp (asOf), address type (EOA/contract/erc20_contract), nonce, ETH balance (wei string), USDC balance, isContract boolean, network (base), ERC-20 token details if applicable (name, symbol, decimals), GoPlus security object with verdict (clean/malicious), isMalicious boolean, and an array of risk flags (phishing, sanctioned, mixer, etc.), plus a human-readable summary string.
Example use cases
Counterparty triage before payment
“I need to pay a freelancer at 0xAbCd1234567890abcdef1234567890abcdef1234 on Base — can you verify whether that address is an EOA or a contract, check its balances, and tell me if GoPlus has any security flags on it before I send the funds?”
DeFi contract safety check
“I found a DeFi protocol at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — can you check if it's a legitimate ERC-20 contract, pull its token details, and run a GoPlus security verdict to see if it's flagged as a honeypot or mixer?”
Suspicious airdrop address investigation
“Someone sent me an unsolicited token from 0xDeAdBeEf0000000000000000000000000000dEaD on Base — can you pull the full address intelligence including its nonce, contract status, and any GoPlus phishing or sanctions flags?”
Technical details
Endpoint
GEThttps://fiatdock.com/v1/chain/address-intel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single comprehensive profile of a Base address before transacting — it bundles address classification, balance lookup, and GoPlus security screening into one pay-per-call request. Prefer it over separate balance or token-metadata endpoints when triaging an unknown counterparty, auditing a suspicious address, or building an agent workflow that must gate payments on a clean security verdict.
Side effects
- Invalid or malformed address returns a 400 error
- Address not found on Base returns empty/zero balances with no flags
- GoPlus service unavailability may result in missing or null security verdict
- Network congestion may cause stale data (asOf timestamp may lag)
- Payment failure via x402 protocol returns 402 Payment Required
