## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability hcrb-in-evm-address-sanctions-screener-c22e707c -d '<json body>'
```

Example prompt: Before I send USDC to 0x742d35Cc6634C0532925a3b8D4C9C6F1b2e3A4f5, can you do a sanctions screen on that wallet address to check if it's blocked or flagged?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
