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 lion-verified-company-domain-dns-https-trust-enrichment-650fbb0d
```

Example prompt: Can you check the DNS and email security setup for stripe.com — I want to know if they have MX, SPF, and DMARC configured, and what their HTTPS trust score looks like?

## When to prefer this

Choose this endpoint when you need real-time, live DNS record lookups combined with an HTTPS trust score in a single low-cost call ($0.005 USDC). Prefer it over static WHOIS or passive databases when freshness matters — e.g. verifying current email security posture before sending or accepting communications. It is keyless and uses x402 micropayments, making it suitable for agent workflows without pre-registered credentials.

## Known failure modes

- Domain does not exist (NXDOMAIN) — may return empty records or error
- DNS lookup timeout for slow or unresponsive nameservers
- Domain missing MX/SPF/DMARC — returns absent fields rather than failing
- Invalid domain format in query parameter — returns validation error
- Payment not processed / x402 challenge not satisfied — returns 402 status

## How this service works

Domain enrich for agents: live DNS (MX/SPF/DMARC/A) + HTTPS trust score. $0.005 keyless Base USDC. ?domain=stripe.com

## Output

Returns live DNS record data including MX records (mail servers), SPF TXT record, DMARC policy record, and A records, along with a computed HTTPS trust score indicating the domain's web security posture. Response is cryptographically attested via Ed25519 signature per LION's architecture.
