How this service works
Exact EVM-address comparison against the identified address snapshot and existing operator block policy. Current legal status is unknown; is_sanctioned is null. valid=false preserves a local block; valid=null never authorizes a transaction. Names are not screened. Missing, stale or incomplete evidence is explicit; no UN/EU coverage or sanctions clearance is provided.
Output
Returns a JSON object with: a valid boolean (false means a local block is preserved, null means authorization was never granted), an is_sanctioned field (null when legal status is unknown), evidence completeness flags indicating whether data is missing or stale, and a note that UN/EU coverage and full sanctions clearance are not provided. The result reflects an exact EVM-address snapshot comparison plus operator block policy.
Example use cases
Pre-payment wallet compliance check
“I'm about to pay a contractor at 0xAbC123def456...7890 — can you run a sanctions screen on that address to make sure it's not blocked before I transfer funds?”
DeFi protocol counterparty screening
“Screen the address 0x1234567890abcdef1234567890abcdef12345678 against sanctions lists and tell me if your operator block policy has flagged it — I need to know if it's safe to interact with.”
Jurisdiction-level sanctions check
“Can you check whether Iran is currently subject to sanctions in your coverage? I want to know the legal status before onboarding any counterparties from that jurisdiction.”
Technical details
Endpoint
POSThttps://hcrb.in/v1/tools/sanctions-address-screen/call?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic, per-address sanctions pre-check for EVM wallets before executing on-chain transactions or payments. It is best suited for agent pipelines that require a binary block/allow signal based on an operator-maintained snapshot plus block policy, and where the cost of a false negative is mitigated by downstream compliance layers. Prefer this over broader KYC services when you only need address-level screening (not name or entity screening) on EVM-compatible chains. Do not rely on it as a sole compliance gate for jurisdictions requiring UN or EU sanctions coverage.
Side effects
- Input address not in 0x... EVM format — schema validation error
- Stale snapshot data — evidence flagged as incomplete or missing
- is_sanctioned returns null — legal status genuinely unknown, not a clearance
- valid returns null — means authorization was never granted, not that address is clean
- No UN or EU sanctions database coverage — endpoint does not provide full international clearance
- Names (not addresses) are not screened by this endpoint
