How this service works
Email verification: is one address deliverable, disposable or a role account? Check ONE email address before you send to it: pass ?email=name@domain.com and get a verdict (deliverable-domain, role-account, disposable, bad-shape or no-mail-domain) from its shape, its MX records read live over DNS, 25 known disposable-mail domains and 27 role-account names like info, support and admin. The mailbox itself is not probed, and the answer says so. Paid in USDC on Base.
Output
Returns a verdict string for the email address, one of: 'deliverable-domain', 'role-account', 'disposable', 'bad-shape', or 'no-mail-domain'. The response clarifies that the mailbox itself is not probed — only domain shape, live DNS MX records, a list of 25 known disposable domains, and 27 known role-account prefixes are checked.
Example use cases
Pre-send email deliverability check
“Before I send this outreach email to contact@startup.io, can you verify it's actually deliverable — check the domain has MX records and it's not a throwaway or generic role address?”
Lead quality screening
“I just captured the email signup noreply@tempmail.com on my form — can you run it through the email validator to tell me if it's a disposable domain or a role account before I add it to my CRM?”
Onboarding form validation
“A user just signed up with admin@guerrillamail.com — can you check that email to see if it's disposable, a role account, or has a bad domain shape so I know whether to flag the account?”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/email-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate a single email address quickly and cheaply before sending, storing, or acting on it — especially when you care about distinguishing disposable, role-account, and undeliverable domains without actually probing the mailbox. Prefer this over the batch endpoint when you only have one address to check. Use it over generic email regex validators when you need live DNS MX verification and disposable/role-account detection.
Side effects
- Missing or malformed email query parameter returns an error
- Invalid email shape (no @ symbol, missing TLD) returns 'bad-shape' verdict
- Domain with no MX records returns 'no-mail-domain'
- DNS lookup timeout may cause delayed or failed response
- Payment failure in USDC on Base blocks the request
- Rate limiting if too many calls made in quick succession
