# trust.nsgoods.org Address Risk Screener

> trust.nsgoods.org Address Risk Screener is a paid API for AI agents from trust.nsgoods.org, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-16).

Screens a crypto wallet address for OFAC sanctions and GoPlus malicious/soft-flag signals across EVM chains and Solana, returning a signed verdict of clean, review, or deny.

## 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 trust-nsgoods-org-address-risk-screener-fef9dd75
```

Example prompt: Before I send any funds, screen this Ethereum wallet 0x1234567890abcdef1234567890abcdef12345678 for OFAC sanctions and any GoPlus risk flags, and tell me whether the verdict is clean, needs review, or should be denied.

## When to prefer this

Use this endpoint when you need a fast, signed, multi-source wallet risk signal that combines OFAC sanctions data (via Chainalysis oracle, EVM chains) with GoPlus behavioral flags in a single pay-per-call call. Prefer it over building your own screening pipeline when you need cryptographic attestation of the result, support for both EVM chains (Ethereum, Base, BSC, Polygon, Mantle) and Solana, and a simple clean/review/deny verdict without requiring a full AML platform subscription.

## Known failure modes

- Invalid or malformed wallet address format returns an error (EVM must be 0x + 40 hex chars, Solana must be 32-44 base58 chars)
- Unsupported chain value outside the allowed enum returns a validation error
- OFAC oracle unavailable may degrade EVM screening results
- GoPlus API outage may reduce soft/hard flag coverage
- Payment failure on Base mainnet ($0.005 USDC) blocks the call
- Solana addresses do not receive OFAC Chainalysis screening (EVM-only)

## How this service works

Address-risk screening for a raw wallet address across EVM chains + Solana — signed JSON with OFAC (Chainalysis oracle, EVM-only) + GoPlus hard/soft flags. Signals only, no decision imposed. USDC pay-per-call on Base mainnet.

## Output

Returns a signed JSON object containing the wallet address, chain, boolean flags for sanctioned and malicious status, arrays of hard_flags and soft_flags (e.g. mixer use, darknet exposure), a screening_verdict enum of 'clean', 'review', or 'deny', the signer identity, and a cryptographic signature for attestation.
