About this item

  • Live. The call checks the email when you make it.
  • Nothing to buy first: you pay as you go. You pay per call.
  • One call. You send data (the emails, one a line) or a CSV file, webhook, rerun_frequency to POST /verifier/upload. The call returns a job: another call reads its answer, or the provider sends it to a URL you give.
  • Who can get it: anyone 18 or over. Keep data: no limit. Use data: with conditions.
