Dmarc Check

Audits a domain's email authentication posture: DMARC, SPF, and DKIM in one check.

Overview

Audits a domain's email authentication posture: DMARC, SPF, and DKIM in one check. Reads the domain's DNS TXT records, parses each protocol's record (SPF mechanisms + qualifiers, DMARC tags p/sp/rua/ruf/pct/aspf/adkim, DKIM selectors with key bits and algorithm), and returns a 0-100 score, A-F grade, and per-finding human-readable reasons explaining the score. Use it as a mail-auth posture audit, spoofing-resistance grader, phishing-readiness scanner, domain email security score, dmarcian-style report, or pre-send deliverability check.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/dmarc-check \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/dmarc-check \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
