## 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 spendpreflight-risk-check-d3a980f1
```

Example prompt: Before you pay crypto-parts-supplier.com at wallet 0xAbC123, run a SpendPreflight sanctions and risk check on the merchant name 'Crypto Parts Supplier', their domain crypto-parts-supplier.com, and that wallet address — I need to know the risk level and any flags before we proceed.

## When to prefer this

Use SpendPreflight when an AI agent is about to execute an x402 crypto payment and needs a fast, low-cost ($0.01 USDC) pre-authorization risk check combining OFAC sanctions screening with domain intelligence. Prefer this over manual compliance checks or heavier KYC pipelines when you need a lightweight, programmatic preflight gate for autonomous payment agents. Best suited for scenarios where speed and cost-efficiency matter more than a full legal compliance certification.

## Known failure modes

- Missing required query parameters returns an error — at least one of name, domain, or address should be provided
- Invalid or malformed wallet address may return null for address_match rather than an error
- Newly registered domains may show limited registrar data
- Sanctions data is only as current as the data_as_of timestamp; stale data is not flagged by the API
- Network or service unavailability returns a non-200 status with no risk assessment

## How this service works

Operated by SpendPreflight: sanctions screening and allow/hold/block preflight for x402 payments.

## Output

Returns a risk level (low/medium/high), a list of risk flags (e.g. 'new_domain'), domain intelligence (DNS records, registration age, registrar, registration date, errors), OFAC SDN sanctions matches for the name and address, and a disclaimer noting the data is informational only and sourced from the public OFAC SDN list as of a stated date.
