How this service works
Disposable email detector / fake email filter / fraud signup defense. Cross-checks 100k+ disposable domains list. Flags role accounts (admin@, noreply@). Verifies MX record via Cloudflare DoH.
Output
Returns whether the email is from a known disposable/temporary domain (from a 100k+ domain blocklist), whether it is a role-based account (e.g. admin@, noreply@), and whether the domain has a valid MX record as verified via Cloudflare DNS-over-HTTPS.
Example use cases
Example prompt
“Can you check if 'user1234@mailnull.com' is a disposable or fake email — I want to know if it's a throwaway address, a role account, and whether its domain has valid MX records before I let it register on my platform?”
Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/disposable-email-checkWhen to prefer
Use this endpoint when you need to block throwaway, burner, or role-based email addresses at signup or lead capture — especially when you want MX record verification combined with a large static blocklist in a single low-cost call. Prefer this over purely regex-based checks or simple MX-only validators when fraud prevention and disposable-domain coverage are both required.
Side effects
- Invalid or malformed email address returns a validation error
- Network timeout on Cloudflare DoH MX lookup may cause partial result
- Unknown or very new disposable domains may not be in the 100k+ list and could be missed
- Payment of $0.01 USDC not received results in 402 Payment Required response
