About this item

  • Live. Opsis looks up the email address you send when you call the API.
  • 3 of the 13 key fields we check. About, Location, Photo.
  • A balance you top up. You pay $20 or more. You spend the whole balance on calls. $20 gets you 50 credits. That covers 50 calls. Calls stop once your credits run out. Credits never expire.
  • One call. You send query to POST /v1/searches. You set type to "email". You can also send wait and stream. 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 18 or older with an active Pro plan. Keep data: no limit. Use data: with conditions.
