How this service works
A trust verdict for one Base wallet: OFAC SDN exact-match against a dated snapshot, wallet age, activity level, and an address-poisoning scan of its recent token transfers, combined into SAFE, CAUTION, or AVOID with a 0-100 score and itemized reasons. Use this when an agent must decide whether a wallet is safe to pay or take instructions from.
Output
A JSON object containing a verdict label (SAFE, CAUTION, or AVOID), a numeric trust score from 0 to 100, OFAC SDN exact-match result against a dated snapshot, wallet age, activity level, address-poisoning scan results from recent token transfers, and a list of itemized reasons explaining the verdict.
Example use cases
Pre-payment counterparty screening
“I'm about to pay 0xAbCd...1234 on Base — can you check if that wallet is safe to send funds to, or if it's on any sanctions list or flagged for suspicious behavior?”
Validate agent instruction source
“My automated agent just received payment instructions from 0x9876...efab — before it acts on them, can you verify whether that Base wallet is trustworthy or potentially a poisoned address?”
Compliance check before onboarding
“We're considering accepting payments from wallet 0xDEF0...5678 on Base — can you screen it for OFAC sanctions and give me a risk score so I know if we're safe to proceed?”

Use this endpoint when an agent needs a quick, multi-factor trust decision about a Base wallet before sending funds or acting on instructions from it. It combines OFAC compliance, on-chain behavioral signals, and address-poisoning detection in a single call, making it ideal for pre-payment screening or agent-to-agent trust verification on Base without building a multi-step compliance pipeline.
Side effects
- Invalid or malformed wallet address returns a 400 error
- Address not found on Base returns low-activity or insufficient-data verdict
- OFAC snapshot may be dated, missing very recent designations
- Address-poisoning scan limited to recent token transfers only, older attacks may be missed
- Service unavailability on Railway returns 5xx
