# Domain Age & Maturity Checker

> Domain Age & Maturity Checker is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Determines a domain's age from WHOIS registration data and Wayback Machine archival history, returning creation date, age in years, archive stats, and a maturity signal for fraud/phishing detection.

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 domain-age-maturity-checker-5fe28e37
```

Example prompt: Can you check how old the domain suspicioussite.com is — I want to know when it was registered, how mature it is, and whether it looks like a freshly minted phishing domain?

## When to prefer this

Use this endpoint when you need to assess the trustworthiness or legitimacy of a domain by its age and archival footprint — especially for fraud detection, phishing link analysis, vendor vetting, or any workflow where a newly registered domain is a red flag. Prefer this over generic WHOIS lookups when you need the combined registration + archive history + maturity signal in one call.

## Known failure modes

- Domain not found in WHOIS or RDAP — returns null dates with a low score
- Unregistered domain — may return no creation date
- Rate limiting on upstream WHOIS/archive services — may return partial data
- Invalid domain format — returns validation error
- Very new domain with no archive history — archive fields return null

## How this service works

Determine a domain's age from registration data and archival history — returns creation date, age in years, first Wayback Machine capture, total archived snapshots, and a maturity signal so agents can assess domain trustworthiness and detect freshly registered domains used for fraud or phishing.

## Output

Returns a JSON object with: the domain name, ISO creation date (created_at), age in days and years, the first Wayback Machine capture timestamp (first_archived_at), estimated total archived snapshots (archive_snapshot_estimate), the number of days between registration and first archive (registration_to_archive_gap_days), the data source used (age_source), a maturity label (e.g. 'established', 'new'), a trust grade letter, a numeric trust score, and an array of findings/flags.
