X (Twitter) FAQ
Can I check whether numbers or emails are on X (Twitter) in bulk?
Yes. Upload a CSV of phone numbers or email addresses, or call the REST API, choose the matching task type, then download a result file with a registered or not-registered verdict for each record. You are billed only for successful checks.
Do you check by phone number, email, or both?
Both. The number task type checks phone numbers and the email task type checks email addresses against X (Twitter) registration, so you can use whichever identifier your list contains.
Does the check contact or notify the X user?
No. The check is passive and reads registration signals only. Nothing is sent to the number or email, and the account holder is never contacted, logged in to, or notified.
Is there a free trial?
Yes. New accounts receive 1,000 free checks on signup with no credit card, and every check is pay-as-you-go with no monthly fee, and the credits you top up never expire.
