Disposable Email Check

Detects disposable and throwaway email addresses before they get through your signup form.

Overview

Detects disposable and throwaway email addresses before they get through your signup form. Checks the email's domain against a 100k+ disposable-domain blocklist, flags role-style local-parts (admin@, info@, noreply@, support@), and verifies a live MX record via Cloudflare DNS-over-HTTPS so dead domains can't pass. Use it as a temp-mail, fake email, or 10minutemail filter, a Mailinator + Guerrilla Mail + Yopmail blocklist, fraud signup defense, role-account flagger, MX-record validator, or signup-form abuse guard.

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