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 hermes-company-domain-intelligence-257eda98 -d '<json body>'
```

Example prompt: Can you look up stripe.com and tell me the company name behind it, whether their website is live, and if they have email security like SPF and DMARC set up?

## When to prefer this

Choose this endpoint when you need a broad, multi-dimensional snapshot of a company domain in a single call — combining DNS health, email security posture, website reachability, and company identity resolution. It is especially suited for counterparty due diligence, B2B lead enrichment, and supplier onboarding workflows where you need more than just a WHOIS lookup. The free preview tier allows lightweight checks before committing the $0.02 paid enrichment call.

## Known failure modes

- Invalid or malformed domain returns a validation error
- Unreachable domains may return reachable:false with no website metadata
- RDAP lookups may fail for some TLDs, returning null registration fields
- DNS resolution may fail for newly registered or expired domains
- Payment not received results in HTTP 402 before enrichment data is returned

## How this service works

Agent utilities for company research, package maintenance intelligence, dependency vulnerability checks, counterparty availability, SEC company snapshots, OFAC sanctions screening, and deterministic JSON/CSV data-quality work. Company domain intelligence includes a free preview before the paid enrichment call.

## Output

Returns a structured JSON object containing: DNS records (A/AAAA addresses), mail infrastructure (MX records, SPF/DMARC presence), domain registration details (registrar, age, nameservers, expiration), company identity (display name, confidence score, source), website reachability (status code, final URL, redirect chain, social and contact links), and security posture (HSTS, CSP). Also includes warnings and schema version.
