## 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 domain-typosquat-analysis-via-x402-micropayment-0ed879d3
```

Example prompt: Check whether 'paypa1.com' is a typosquat or suspicious domain — I need to know if it's flagged for OFAC issues or looks like it's impersonating a real brand.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call domain risk assessment combining typosquat detection, OFAC screening, and billing verification in a single lookup, especially in agent workflows where per-query micropayments via x402/USDC are acceptable and no standing subscription is needed.

## Known failure modes

- Missing required query parameter (domain, host, or url) returns an error
- Invalid or malformed domain input may return an empty or null result
- Payment failure via x402 protocol blocks access to the endpoint
- OFAC database unavailable may cause partial or degraded results
- Unknown or very new domains may yield limited analysis data

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a success flag and a result payload containing typosquat detection signals, OFAC screening status, and billing verification data for the queried domain or hostname.
