## 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 agosint-domain-due-diligence-614c8b8c -d '<json body>'
```

Example prompt: Can you pull the full domain intelligence report for stripe.com — I need DNS records, TLS details, domain age, mail security, and any risk signals?

## When to prefer this

Use this endpoint when you need structured, multi-source domain intelligence in a single call — combining RDAP/WHOIS, DNS, TLS, hosting, and mail security data — especially for vendor due diligence, KYB workflows, or phishing investigation. Prefer this over raw WHOIS lookups when you need signed, agent-ready JSON output with risk signals and no account setup required.

## Known failure modes

- Invalid or malformed domain name returns a validation error
- Domain not found in RDAP/WHOIS returns empty or partial records
- TLD not covered by RDAP falls back to WHOIS with potentially less structured data
- Network timeout reaching upstream registries returns a partial result or error
- Stablecoin payment failure or insufficient balance returns 402 Payment Required

## How this service works

Company and domain due diligence for AI agents: official registers, sanctions lists and domain records, signed. Pay per call in stablecoins, no account.

## Output

Returns a structured JSON object containing DNS records, TLS certificate details, RDAP/WHOIS registration data (including domain age in days), hosting information, mail security configuration, risk signals array, entity hints, source URL, and a signed receipt confirming the lookup.
