How this service works
Verdix lite ($0.01): call before an agent sends funds to an unfamiliar EVM address on Base, when cost matters most. Checks OFAC sanctions, scam/phishing lists, address poisoning, phishing tokens and flagged deployers. A clean answer is no_known_risk, never safe; for a verdict that can say safe, call /risk/address/quick.
Output
Returns a risk classification for the queried Base EVM address, indicating whether it has no known risk (clean) or has been flagged across the checked categories: OFAC sanctions lists, known scam/phishing databases, and live address poisoning detection. A 'no_known_risk' result means the address passed the limited checks, not that it is guaranteed safe. The lite tier performs fewer checks than the quick, standard, or deep tiers.
Example use cases
Pre-payment sanction screening for DeFi
“I'm about to send USDC to 0xDeF9876543210fedcba9876543210fedcba987654 on Base — can you run a quick Verdix lite check to see if it's on any OFAC or scam list before I confirm?”
Address poisoning detection for airdrop
“We're distributing tokens to a list of Base addresses — can you run the cheapest Verdix address check on 0x1111111111111111111111111111111111111111 to see if it looks like an address poisoning attempt?”
Wallet safety check for marketplace payout
“I need to pay out a seller at 0xAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAa on Base — run a lite Verdix risk check first so I know if they're flagged as a scammer or phisher.”
Technical details
Endpoint
POSThttps://api.verdixapi.com/risk/address/lite?utm_source=zero.xyzWhen to prefer
Choose the lite tier when you need the absolute lowest-cost pre-payment screening ($0.01) and can tolerate a limited check set — ideal for high-volume, low-value transactions where you want a quick sanity check rather than comprehensive due diligence. For first-time payments, large amounts, or higher-stakes transactions, prefer the quick ($0.02), standard ($0.10), or deep ($0.50) tiers which cover more risk signals. Use this endpoint when budget is the primary constraint and a 'no_known_risk' result is sufficient to proceed.
Side effects
- Invalid address format (not a valid 0x EVM address) — returns validation error
- Chain not supported (only 'base' is currently accepted) — returns error
- Payment failure or insufficient USDC balance — request rejected before processing
- Address not found in any database — returns no_known_risk (not a guarantee of safety)
- Service unavailable or timeout — returns 5xx error
