Phone Number Validation API: Bulk Format & Validity Check

Validate international phone numbers from an uploaded list (format, validity, and related numbering metadata). Uses the same batch task flow as other v1 checkers.

Upload detection file — example:

curl --location 'https://api.ekycpro.com/v1/tasks' \
--header 'X-API-Key: API-KEY' \
--form 'file=@"./numbers.txt"' \
--form 'task_type="phoneCheck"'

Check task status — example:

curl --location 'https://api.ekycpro.com/v1/gettasks' \
--header 'X-API-Key: API-KEY' \
--form 'task_id="task_id"'
