How this service works
x402-Werkzeuge für autonome Agenten.
Output
Returns a numeric security score (0–100), per-check results for SPF, DMARC, and DKIM (including record values and weak/missing status), a spoofing risk rating (e.g. 'hoch'/'high'), a list of prioritized findings with severity levels, human-readable explanations in German and English, and actionable DNS fix suggestions. Includes the domain checked and timestamp.
Example use cases
Pre-send domain security audit
“Before we launch our email campaign, can you check the email security records for ourfirm.com and tell me if we have any critical issues with SPF, DMARC, or DKIM that could cause deliverability problems?”
Investigating phishing risk for a client domain
“A client thinks their domain brandname.com might be getting abused for phishing — can you run a full email security check and tell me the spoofing risk level and what records are missing or weak?”
Verifying third-party vendor email setup
“We're onboarding a new vendor at vendordomain.net — can you check their email authentication configuration, including DKIM selectors 'mandrill' and 'sendgrid', and give me a security score so I can assess their trustworthiness?”
Technical details
Endpoint
POSThttps://tools.netzhandwerker.de/v1/email/securityWhen to prefer
Use this endpoint when you need a structured, scored audit of a domain's email authentication stack (SPF, DKIM, DMARC) with actionable remediation hints, especially for autonomic agent workflows that require machine-readable severity levels and bilingual (DE/EN) output. Prefer this over generic DNS lookup tools when you need a composite security score and spoofing risk assessment rather than raw record data.
Side effects
- Invalid or non-existent domain returns error or empty results
- DNS lookup timeouts for slow or unresponsive nameservers
- DKIM selectors not found if none of the standard 25 or custom selectors match
- Cache returning stale results if no_cache is not set (6-hour TTL)
- Exceeding the 25 custom DKIM selector limit returns a validation error
