## 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 bytemine-fraud-check-a5bc6425 -d '<json body>'
```

Example prompt: Can you check this signup for fraud risk — the email is john.k4823x@mailtemp.org, the IP is 185.220.101.42, and the name they gave is 'John Kelvin'? I need to know if I should allow, review, or block this registration.

## When to prefer this

Choose this endpoint when you need a real-time, per-signup fraud signal that combines both email hygiene and IP reputation in a single call. It is ideal for gating new user registrations, free trial signups, or lead form submissions where you want a structured allow/review/block decision without building your own rules engine. Prefer this over generic email validation tools when you need IP intelligence (VPN, Tor, proxy detection) alongside email checks, and over raw IP lookup services when you also want disposable email and MX validation bundled together.

## Known failure modes

- Neither email nor IP provided — request rejected as at least one is required
- Invalid email format — may return validation error or low-confidence signal
- Private or reserved IP address (RFC1918) — may return bogon flag or inconclusive result
- Unknown or newly registered domain — domain liveness check may be inconclusive
- Network timeout reaching external DNS or IP intelligence sources — partial signals returned

## How this service works

Score a signup for fraud risk. Send email only, ip only, or both; at least one is required. Email checks cover disposable and free provider detection, MX validation, gibberish name detection, domain liveness, and known business signals. IP checks cover VPN, proxy, Tor, residential relay, datacenter, and bogon detection. Returns a decision of allow, review, or block with a risk score and itemized signals.

## Output

Returns a decision of 'allow', 'review', or 'block', a numeric risk score, and itemized signals covering email checks (disposable/free provider, MX record validity, gibberish name detection, domain liveness, business signals) and IP checks (VPN, proxy, Tor, residential relay, datacenter, bogon detection).
