Request a waitlist confirmation email.

POST
/v1/waitlist
curl --request POST \
  --url https://api.opdns.io/v1/waitlist \
  --header 'Content-Type: application/json' \
  --data '{ "email": "[email protected]", "consent": true }'

Public and rate-limited. Requires explicit consent. Valid submissions always answer 202 with the same body for new, pending and confirmed addresses, including addresses under the durable one-email-per-minute resend limit. New entries are pending; only pending entries receive mail. The API queues mail containing a signed single-use confirmation link valid for 48 hours through the mailer; 202 does not promise delivery. Confirmed entries do not receive another confirmation. Pending entries expire from the waitlist after seven days. Joining does not create an account or issue an invitation; only confirmed entries may be invited.
