Tools 4 found in our last check
list_domainsList the hostnames this API key can receive mail on. Call it first to build a test address: any address at a hostname with receiving=true reaches the inbox. Returns each hostname with its status, and trialEndsAt for a trial hostname.
get_latest_otpGet the newest message sent to one address and the verification code (OTP) extracted from it. Returns found=false while nothing has arrived: wait about 5 seconds and call it again. When the message has no code, such as a verification link, otp is null; call get_message with mess…
list_messagesList recent messages, newest first, optionally only those sent to one address. Returns the id, sender, subject, extracted code and times of each message, not the body; expired messages are left out. Call get_message with an id to read one.
get_messageRead one message by id, with its plain-text body (up to 20,000 characters), for verification links or anything the otp field misses. Returns an error when no message has that id, which also happens once the message expires: after 24 hours on the trial and 72 hours on paid plans.
