Features

✓

Followers list

Returns a users array of the accounts following the given username, so you can enumerate an account's audience member by member.

✓

Profile metadata per follower

Each follower entry includes username and full_name, giving you identifiable profiles rather than anonymous counts.

✓

Cursor pagination

Responses carry end_cursor and has_next_page; feed end_cursor back to walk deep into a large follower base page by page.

✓

Verification status

Every follower reports is_verified, so you can spot notable or verified accounts within an audience and gauge its quality.

Use cases

Audience Analysis

Analyze a creator's follower base for demographics.

Enumerate an Instagram account's followers list

The YepAPI Instagram Followers API returns the actual accounts following a user — a users array with username, full_name, and is_verified for each — rather than just a follower count. A POST to /v1/instagram/user-followers walks a large audience page by page using end_cursor, so you can analyze who follows an account, not merely how many.

It goes deeper than the YepAPI User Profile API, which reports the follower number; Followers reports the followers themselves. Pair it with the Post Likers API to compare audience and engagers, or the Similar Accounts API for lookalikes. One key also covers TikTok, YouTube, SEO, and AI, so audience research spans platforms in one integration.

What is an Instagram followers API?

An Instagram followers API returns the individual accounts that follow a given user, as paginated structured JSON — not the aggregate count, but the actual list. You send {"username": "instagram"} and receive a users array where each entry carries the follower's username, full_name, and is_verified flag, plus an end_cursor to fetch the next page of a large base. It is the tool for auditing who makes up an audience: spotting verified followers, sampling follower profiles for authenticity checks, or mapping overlap between accounts. A profile lookup tells you the size; this tells you the composition.

Build your own Instagram audience-analysis tool

Use the Followers endpoint to sample and analyze a creator's audience: detect likely fake-follower patterns, measure the share of verified followers, or estimate audience overlap between two accounts. Because each follower entry is structured with a verification flag, you can quantify audience quality rather than guess. Walk as deep as you need with end_cursor, and cross-reference results against the YepAPI Post Likers API to see how much of the follower base actually engages.

Instagram User Followers API pricing — $0.01 per call

Each page of followers costs a flat $0.01. Sampling several pages of a large audience for an authenticity audit costs only cents, with no tiers or minimums. The spend shares one balance with every YepAPI endpoint, so audience research scales with how deep you page. You pay strictly per call, never per seat or per month.

Audience lists the official API won't return

Instagram's official Graph API does not expose follower lists at all — it returns only the aggregate follower count, even for accounts you own. The YepAPI Followers API returns the actual follower profiles for any public account by username, with verification flags, so audience-composition analysis and fake-follower detection become possible — capabilities the official API simply does not offer.
