Disposable Email Checker API

GET

Block throwaway email addresses before they become users.

Disposable Email Checker is a disposable email detection API that tests whether an email address belongs to a disposable or temp mail provider. Pass any email to get back the domain parsed from it and a true or false flag showing whether it is temporary. That also makes it a quick way to drop throwaway domains when you derive a company domain from a list of emails.

About the Disposable Email Checker API

Send a complete email address, or just a domain, to check it against a disposable email blocklist of over 100,000 throwaway and temp email domains, updated daily. The check tests both exact matches and parent domains, and separately flags privacy relay addresses such as Apple Hide My Email, DuckDuckGo and Firefox Relay, which forward to a real inbox. Paid plans also read the domain's MX records to name the relay service behind a custom domain and to catch new throwaway domains that receive mail through a known disposable service.

What people use it for

User Registration Screening: To stop fake signups, SaaS apps check user email addresses at registration and reject submissions matching temporary domain lists.
Mailing List Cleaning: Filter out temporary inboxes from marketing contact databases before scheduling newsletter campaigns to protect sender reputation and delivery rates.
Gated Content Verification: When visitors request whitepapers or trial access, verify their email domain immediately to require a genuine corporate or personal inbox.
Promo Abuse Prevention: E-commerce stores evaluate customer emails during checkout to prevent shoppers from repeatedly claiming first-order discounts with burner accounts.

Ways to call it

Questions.

Common questions about the Disposable Email Checker API.

Read the docs →

How often is the disposable domain list updated?

The database updates daily to track newly created disposable email providers. It currently monitors over 100,000 known disposable domains.

Does it catch throwaway addresses that use subdomains?

Yes. The checker matches both exact domains and parent domains against known disposable email providers, so addresses using custom subdomains under a disposable host are still flagged.

Does it flag Apple Hide My Email and other relay addresses?

Yes, through isRelay rather than isDisposable. Relay services such as Apple Hide My Email, DuckDuckGo Email Protection, Firefox Relay, SimpleLogin, Proton Pass and addy.io forward mail to a real inbox the sender never sees. The address works and a person reads it, so you may want to accept it while knowing two relay addresses can belong to the same person. Paid plans add relayService, which names the service and also catches custom domains that route their mail through one.

What do paid plans add over the Free plan?

The Free plan returns isDisposable, isRelay and the parsed domain. Paid plans look up the domain's MX records to add relayService, the name of the relay service handling the address, and isDisposableMx, which flags a domain whose mail is received by a known disposable service. That catches newly registered throwaway domains before they reach the list.

What would checking 10,000 signups a month cost me?

At 6 credits per check, 10,000 checks require 60,000 credits. That easily fits within the Starter plan, which includes 200,000 credits for up to 33,333 checks each month. On Starter, that works out to about $0.0009 per check, or $0.90 per 1,000 checks. The Free plan includes 33 checks per month.

Can I check just a domain name instead of a full email?

Yes. Send domain=mailinator.com instead of email and the same checks run against the domain. When you send a full address, the domain is taken from it automatically.

Can I use this to screen signups on a commercial product?

Yes, provided you are on a paid plan. Commercial use is permitted across all paid plans to protect your own apps and onboarding flows, though you may not resell or redistribute the underlying domain data.

Request parameters — GET /v1/emaildisposablechecker

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Optional

Parameter	Type	Example	Description
`email`Optional	string	`support@myspace.com`	The email address to check (e.g., support@myspace.com). Send this or domain email
`domain`Optional	string	`mailinator.com`	A domain to check instead of a full address (e.g., mailinator.com). Send this or email email

Example request

1
2

curl "https://api.apiverve.com/v1/emaildisposablechecker?email=support%40myspace.com&domain=mailinator.com" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Response — GET /v1/emaildisposablechecker

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "isDisposable": false,
    "email": "support@myspace.com",
    "domain": "myspace.com",
    "isRelay": false,
    "relayService": null,
    "isDisposableMx": false
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`isDisposable`	boolean	`false`	Whether the email address is a disposable address (matched by exact domain or a parent domain of the sender)
`email`	string	`"support@myspace.com"`	The email address that was checked; null when a domain was sent instead
`domain`	string	`"myspace.com"`	The domain that was checked, taken from the email address when one was sent
`isRelay`	boolean	`false`	The domain belongs to an email relay or forwarding service (Apple Hide My Email, DuckDuckGo, Firefox Relay, SimpleLogin, Proton Pass, addy.io, 33mail). Relay addresses stay live and forward to a real mailbox the sender never sees, so they are reported separately from isDisposable
`relayService`Premium	object	`null`	Which relay service handles the address. Also names the service when a custom domain routes its mail through SimpleLogin, addy.io, Apple or DuckDuckGo, which isRelay does not catch; null when no relay service is involved or the MX lookup failed
`isDisposableMx`Premium	boolean	`false`	The domain's mail servers belong to a known disposable email service. Catches newly registered throwaway domains that are not on the list yet, because they still receive mail through the same service; null if the MX lookup failed

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The allowance for the cycle
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 6 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	Disposable Email Checker calls	Per 1,000 calls
Free	Free	200	33	Free
Starter	$29.99	200,000	33,333	$0.90
Pro	$99.99	1,000,000	166,666	$0.60
Mega	$299.99	4,000,000	666,666	$0.45

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
