Instagram ID/Username Profile Checker API: Bulk Profiles

Check Instagram accounts by username (ID) or profile URL and return a rehosted face profile photo cropped from the newest post that contains a face, full name, post count, follower and following counts, and whether the account is private or verified. Accounts that do not exist are returned as not activated; private accounts are returned as activated with their profile fields but without a photo. The task uses the standard asynchronous batch workflow.

Input format

Upload a text file with one Instagram username (ID) per line. username, @username and full instagram.com/<username> URLs are all accepted; values are matched case-insensitively.

Numeric Instagram IDs (pk) are accepted too and resolved to the username.

Operational notes

• The task is asynchronous; use the task ID for status polling.
• Check product-specific input limits before uploading.
• Failed rows are reported in the exported result and reflected in the task counters.
• Photos are cropped from public posts at the resolution Instagram serves to logged-out visitors (640 px), so most crops are below 400 px and reported as ok_small.
• The fields above are based on the current live sample and may change when the upstream export schema changes.
