## Facts

- Price: $0.001/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 domainsignal-dns-security-audit-96d5c840
```

Example prompt: Can you run a DNS security audit on acmecorp.com and tell me what risks are flagged — things like missing DMARC, SPF, or DKIM — and what score it gets?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-result DNS security audit with a machine-readable risk score and actionable recommendations — especially for email security posture checks (DMARC, SPF, DKIM). Prefer it over manual DNS lookups when you want a structured risk score rather than raw DNS records, and over full security scanners when you only need DNS-layer intelligence at low per-call cost.

## Known failure modes

- Invalid or non-existent domain returns an error or empty risk list
- Malformed domain input may cause a 400 bad request
- DKIM selector not provided may result in incomplete DKIM analysis
- Transient DNS resolution failures may produce incomplete results
- Rate limiting or payment failure may return a 402 or 429 response

## How this service works

Pay-per-result domain qualification, DNS security audits, and website intelligence over x402.

## Output

Returns a JSON object containing the domain name, a numeric security score (0-100), a list of identified risks as human-readable strings (e.g. 'DMARC is missing'), and a list of recommendations for remediation.
