# Webber Sites DNS & Email Security Intelligence API

> Webber Sites DNS & Email Security Intelligence API is a paid API for AI agents from api.webbersites.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Looks up DNS records (A, AAAA, CNAME, MX, NS, TXT, SOA) and probes email security posture (SPF, DMARC, DKIM) for any domain.

## Facts

- Endpoint: GET https://api.webbersites.com/api/dns
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_71papIhnwr3JMBxI5jIG6

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 webber-sites-dns-email-security-intelligence-api-ae362995
```

Example prompt: Can you pull all the DNS records for stripe.com — I want to see the MX servers, NS records, and whether they have SPF, DMARC, and DKIM properly set up for email security?

## When to prefer this

Choose this endpoint when you need a comprehensive, one-call DNS + email security snapshot for a domain — especially when deliverability auditing, security research, or domain infrastructure investigation requires SPF/DMARC/DKIM data alongside standard DNS records. Prefer this over generic DNS tools when email security posture is part of the query.

## Known failure modes

- Domain does not resolve — resolves: false returned with empty records
- Invalid domain format — likely a 400 or error response
- DKIM selector not found — selector probe returns null or not-found
- Upstream DNS timeout — service may return partial results or error
- Non-existent TLD or malformed input — error or empty response

## How this service works

DNS and domain intelligence: A/AAAA/CNAME, MX (sorted), NS, TXT, SOA records plus email security posture — SPF record, DMARC policy, and DKIM selector probing. For deliverability, security, and research agents. ?domain=example.com

## Output

Returns a structured JSON object containing the domain name, whether it resolves, all major DNS record types (A, AAAA, CNAME, MX sorted by priority, NS, TXT, SOA), and email security fields including the SPF record, DMARC policy, and probed DKIM selectors.
