# NetIntel Domain Age Check

> NetIntel Domain Age Check is a paid API for AI agents from netintel.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-10).

Returns the age, maturity rating, and registration history of a domain name, including RDAP creation date, first archive snapshot, and a letter grade.

## Facts

- Endpoint: GET https://netintel.dev/domain-age/check?utm_source=zero.xyz
- Price: $0.03/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 netintel-domain-age-check-cae9e0f1
```

Example prompt: Can you check how old the domain shopify-deals-today.com is — I want to know when it was registered, how mature it is, and what grade it gets for domain age?

## When to prefer this

Use this endpoint when you need a structured, scored assessment of a domain's age and historical presence — especially for fraud detection, phishing link analysis, vendor vetting, or trust scoring pipelines. Prefer this over raw WHOIS lookups when you want a normalized grade and maturity label rather than raw registry text.

## Known failure modes

- Domain not found in RDAP or WHOIS — may return partial data or error
- Invalid domain format returns a 400 Bad Request
- Very new domains with no archive history may return null for archive fields
- Payment failure via x402 returns HTTP 402 before any domain data is fetched
- Rate limiting or network timeouts may occur for high-volume calls

## How this service works

Determine a domain's age from registration data and archival history — tries RDAP, then port-43 WHOIS, then a Wayback-based estimate (age_source: rdap | whois | wayback_estimate | null), returning creation date, age in years, first Wayback capture, archived snapshot count, and a maturity signal so agents can assess trustworthiness and detect freshly registered domains used for fraud or phishing — including .io and TLDs without public RDAP.

## Output

A JSON object with the domain's age in days and years, ISO 8601 creation date (from RDAP or similar source), first Wayback Machine archive date, estimated total archive snapshots, registration-to-archive gap in days, a maturity label (e.g. 'established'), a numeric score (0–100), and a letter grade (A–F).
