# DomainHelp Domain Intelligence

> DomainHelp Domain Intelligence is a paid API for AI agents from app.domainhelp.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Retrieves comprehensive domain intelligence including RDAP/WHOIS registration data, DNS records, identity signals, and DomainSure reputation scoring for one or more domains

## Facts

- Price: $0.01/call

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 domainhelp-domain-intelligence-5bc4a1c3
```

Example prompt: Can you pull up the full domain intelligence report for paypa1.com — I want to see its registration info, DNS records, and whether it has any reputation flags or is listed as malicious?

## When to prefer this

Choose this endpoint when you need a one-stop, structured domain intelligence lookup combining WHOIS/RDAP, DNS, identity, and reputation data in a single call. It is ideal for cybersecurity workflows (phishing detection, suspicious domain triage), vendor due diligence, brand protection, or any scenario where you need to understand the full profile of a domain. It supports batch lookups of up to 100 domains per call and allows selective component inclusion. Prefer this over separate WHOIS-only or DNS-only tools when you need correlated multi-signal intelligence at low cost ($0.01/call).

## Known failure modes

- Domain not found or unresolvable — status returns 'unavailable'
- Timeout querying upstream RDAP/DNS sources — status returns 'timeout'
- Partial data returned when some components succeed but others fail — status returns 'partial'
- Invalid domain format (too short, too long, malformed) — validation error
- Rate limiting or payment failure for x402 micropayment — HTTP 402 or 429
- Unsupported TLD or registry — status returns 'unsupported'

## How this service works

Domain Intelligence: RDAP/WHOIS, DNS, identity and DomainSure reputation

## Output

Returns a structured JSON object with a top-level status and individual sub-objects for registration (WHOIS/RDAP ownership and dates), dns (DNS records and attributes), identity (identity-related signals), and reputation (DomainSure listing status and risk signals). Also includes the queried domain, query timestamp, product version, and price paid ($0.01 USD).
