Tools

create_inbox
Invent a fresh, unused disposable email address you can give out immediately. Nothing is created or reserved server-side — an address exists as soon as mail arrives at it — so this never fails and needs no account. Public domains: grabmail.io, mixozia.com, linqmail.com, plimbox.com, mavobox.com, plupmail.com, zonkbox.com, wazbox.com. With a paid key sent as Authorization: Bearer, a premium-pool domain from list_domains works too.
shallow
delete_message
Remove a message now rather than waiting for it to expire. Idempotent.
shallow
list_domains
The public domains anyone may use. A domain of your own needs no account or key either — just an MX record pointing here. These public domains are on disposable-mail blocklists; if a form rejects them, see the premium pool noted in the result. With a paid key sent as Authorization: Bearer, the result also lists the premium-pool domain names.
shallow
list_messages
Everything waiting at an address, newest first. Returns immediately, including when the mailbox is empty — use wait_for_message if you are expecting something that has not arrived yet.
shallow
read_message
The full message: sender, subject, plain text, HTML and any attachments. This is where a confirmation code or a sign-in link will be. Read `text`: when the sender shipped HTML only, as most transactional mail does, it holds a plain-text rendering of that HTML rather than nothing, with link targets and image alt text kept.
shallow
wait_for_message
Blocks until a new message arrives at the address, then returns it in full — the tool to use after submitting a sign-up form. Waits at most 25 seconds and then returns with timed_out set to true; call it again to keep waiting. Optionally waits for a message from a particular sender or with particular words in the subject, ignoring anything else that arrives.
