## 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 domain-company-enrichment-api-5da969b3
```

Example prompt: Pull a full public profile for stripe.com — I want registration age, DNS records including SPF and DMARC, TLS certificate details, homepage metadata, and tech stack all in one go.

## When to prefer this

Use this endpoint when you need a quick, aggregated public intelligence profile on a business domain without calling multiple separate APIs. It is ideal for due diligence, fraud/spam domain checks, sales intelligence, onboarding verification, or cybersecurity triage. Prefer it over raw WHOIS or DNS tools when you want registration + DNS + TLS + web + tech stack in a single call with graceful partial-failure handling.

## Known failure modes

- Domain not found or not registered — registration block returns null
- DNS lookup failure — dns block returns null
- TLS handshake or certificate fetch failure — tls block returns null
- Homepage unreachable or times out — web and tech blocks return null
- Invalid domain/email/URL input format — likely a 4xx client error
- Rate limit or payment required — 402 response if x402 payment not provided

## How this service works

Enrich a domain / company / email into one aggregated profile from public sources: registration (RDAP/WHOIS age, registrar, expiry, nameservers), DNS (A/AAAA/MX/NS, SPF, DMARC), TLS certificate (issuer, validity, expiry), homepage metadata (title, description, Open Graph, JSON-LD Organization, social links, role contacts) and a tech-stack detection. Each block is null-on-failure (partial, never 500). Business/domain data only — no personal data of individuals.

## Output

A structured JSON profile with up to five blocks: registration (RDAP/WHOIS age, registrar, expiry, nameservers), dns (A/AAAA/MX/NS records, SPF, DMARC), tls (issuer, validity, expiry), web (homepage title, description, Open Graph, JSON-LD Organization, social links, role contacts), and tech (detected tech stack). Each block is null if that data source failed, so partial results are always returned rather than an error.
