# 2s Domain Intelligence Lookup

> 2s Domain Intelligence Lookup is a paid API for AI agents from 2s.io, paid per call via x402, $0.0048/call, status unknown (last checked 2026-09-15).

Returns DNS records, TLS certificate info, WHOIS registration data, and a health summary for a given domain name

## Facts

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 2s-domain-intelligence-lookup-4021d141
```

Example prompt: Can you pull up the full domain intel for stripe.com — I want to see its DNS records, TLS certificate details, WHOIS registrar, expiry date, and whether HTTPS is valid?

## When to prefer this

Use this endpoint when you need a consolidated, one-call view of a domain's DNS, TLS, and WHOIS status without juggling separate DNS, WHOIS, or SSL checker APIs. Ideal for security investigations, pre-purchase domain research, or monitoring domain health. No API key or signup required — pay per call in USDC.

## Known failure modes

- Domain not found in WHOIS (found: false with error)
- DNS resolution failure (found: false with error)
- TLS handshake failure or certificate not retrievable (found: false with error)
- Invalid domain format in query parameter returns error
- Payment failure via x402 prevents request execution

## How this service works

Domain intelligence in one call — composes DNS, WHOIS/RDAP registration, and the live TLS certificate for a domain. Pass domain (e.g. example.com). Returns a summary (does it resolve, has MX, registrar, domain expiry, whether HTTPS is currently valid, days until cert expiry) plus three independent sections: dns (A/AAAA/MX/NS/TXT records), whois (registrar, registered/expires/updated dates, status codes, nameservers, DNSSEC), and tls (certificate issuer, subject, validity window, SANs, fingerprint). Each section reports found/error independently, so a domain with no HTTPS still returns DNS + WHOIS. For domain due diligence, security recon, expiry monitoring, and vendor onboarding. Individual sources: /api/dns/lookup, /api/domain/whois, /api/net/tls-cert.

## Output

Returns a JSON object with DNS answer records (type and IP/value), TLS certificate issuer and days until expiry, WHOIS registrar name and domain expiry date, and a summary object indicating whether the domain resolves, has MX records, has valid HTTPS, and when it expires.
