# Agent Tools – Full Email Risk Check

> Agent Tools – Full Email Risk Check is a paid API for AI agents from agents.crowdspark.me, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-31).

Performs a comprehensive email risk assessment combining address validation, disposable detection, MX checks, sender domain health signals (age, registrar, SPF, DMARC, website reachability), and a 0–100 risk score with an accept/review/reject verdict.

## Facts

- Endpoint: GET https://agents.crowdspark.me/v1/email/full?utm_source=zero.xyz
- Price: $0.004/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agent-tools-full-email-risk-check-2bc02cbf
```

Example prompt: Run a full risk check on jane@acme.com — I need the risk score, accept/review/reject verdict, and domain health details like SPF, DMARC, domain age, and whether the website is reachable.

## When to prefer this

Choose this endpoint over the basic email_check endpoint when you need both address-level validation AND sender domain intelligence in a single call — especially for fraud screening, signup gating, or lead qualification where SPF/DMARC posture, domain age, and registrar context are needed alongside a quantified risk score and actionable verdict.

## Known failure modes

- Invalid or malformed email address returns an error or empty result
- Unresolvable domain may cause domain_health fields to be null or missing
- Timeout on external domain lookups may result in incomplete domain_health data
- Rate limiting if too many calls are made in a short window
- Payment failure (402) if USDC balance is insufficient

## How this service works

## Output

Returns a JSON object with the original email, a risk_score (0–100), a verdict (accept / review / reject), a disposable flag, risk_reasons array, has_mail_server flag, and a domain_health object containing SPF record, DMARC record, domain age in days, registrar name, and website_reachable boolean.
