How this service works
Checks whether an email address's domain (or a domain you give) is on the community disposable and temporary email blocklist (about 9,900 domains). Only the domain is checked, never the mailbox, and a domain missing from the list is not proven to be permanent.
Output
Returns a boolean or status indicating whether the queried domain appears on the community disposable/temporary email blocklist (~9,900 domains). The mailbox portion of the email is ignored; only the domain is checked. A negative result (not on list) does not guarantee the domain is permanent.
Example use cases
Block throwaway emails at signup
“A user just tried to register with the email temp4892@guerrillamail.com — can you check if that domain is on the disposable email blocklist before we let them in?”
Validate lead email quality
“We just got a CRM lead with the email address contact@yopmail.com — can you tell me if that's a known disposable email domain so I know whether to follow up?”
Screen bulk user list for junk emails
“Check whether trashmail.com is flagged as a disposable or temporary email provider — I want to filter it out of our mailing list.”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/security/email-disposable?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost check against a large community-maintained blocklist of disposable email domains — ideal for signup validation, lead scoring, or fraud prevention workflows. Prefer this over manual domain checks or full email verification services when you only need to know if a domain is commonly associated with throwaway accounts and do not need inbox reachability testing.
Side effects
- Missing 'email' query parameter returns a 400 or error response
- Domain not found in list returns a negative/false result, which does not confirm the domain is legitimate
- False negatives are possible for newer or obscure disposable email domains not yet in the community list
- Rate limiting or payment failure (x402) may block requests if USDC balance is insufficient
- Invalid or malformed email/domain input may cause unexpected results
