Email Spam Check

Scores whether an address and domain are likely to receive mail cleanly, using syntax validation, MX records, disposable-domain signals, role-account detection, SPF, DMARC, and DKIM posture.

Overview

Scores whether an address and domain are likely to receive mail cleanly, using syntax validation, MX records, disposable-domain signals, role-account detection, SPF, DMARC, and DKIM posture. Privacy-safe DNS and public blocklist checks only; no recipient mailbox probing. Use it as an email spam check, inbox readiness API, or email deliverability risk scanner.

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/email-spam-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/email-spam-check \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
