Nothing to pay. You get $1 of credit once, enough for 500 calls. Unused credit expires: may carry an expiry stated when granted.
One call. You send input.email to POST /v1/run. You set capability to "contact.verify". The call returns the answer when the provider is quick. When the provider is slow, the call returns a job. You fetch the answer once the job is done.
Who can get it: anyone who verifies their email. Keep data: no limit. Use data: with conditions.
