Features

✓

Similar accounts

Returns a similar_accounts array of profiles related to the seed username — Instagram's own suggested-account graph, surfaced as structured data.

✓

Profile metadata

Each suggestion includes username and full_name, so the related accounts arrive as usable, identifiable profiles.

✓

Follower counts

Every similar account carries follower_count, letting you rank discovered accounts by reach immediately.

✓

Niche discovery

Because suggestions cluster around the seed account's niche, one lookup expands a single creator into a map of their competitive and topical neighborhood.

Use cases

Find competitors and similar accounts in your niche.

Find accounts similar to any Instagram user

The YepAPI Instagram Similar Accounts API takes one seed username and returns a similar_accounts array of related profiles — each with username, full_name, and follower_count. A POST to /v1/instagram/user-similar taps Instagram's own suggested-account graph, turning a single creator into a map of their niche.

It is the expansion engine of the YepAPI Instagram suite: where the Search API finds accounts from keywords, Similar Accounts finds them from a known anchor. Profile each result with the User Profile API or size their audiences with Followers. One key also covers TikTok, YouTube, SEO, and AI, so lookalike discovery spans platforms in a single integration.

What is an Instagram similar accounts API?

An Instagram similar accounts API returns profiles related to a given account, as structured JSON. Instead of searching by keyword, you anchor on one username you already care about and receive the accounts Instagram associates with it — typically same-niche creators, competitors, and audience-overlapping profiles. You send {"username": "instagram"} and get a similar_accounts array, each entry with username, full_name, and follower_count. It is built for lookalike discovery: expanding a single seed into a ranked neighborhood of comparable accounts, which keyword search alone cannot reliably reproduce.

Build your own Instagram lookalike-discovery tool

Use the Similar Accounts endpoint to expand an influencer shortlist, map a competitive landscape, or seed an outreach list from one known creator. Because each suggestion includes follower_count, you can rank the neighborhood by reach and filter to your target tier instantly. Chain it recursively — feed a discovered account back in to widen the net — and enrich the best matches with the YepAPI User Profile API or audience checks via the Followers API.

Instagram Similar Accounts API pricing — $0.01 per call

Each similar-accounts lookup is a flat $0.01, no tiers or minimums. Recursively mapping a niche across many seed accounts still costs only cents per call, and the spend shares one balance with every YepAPI endpoint. You pay per call only, so lookalike discovery scales with how wide you cast, never with a subscription tier.

Niche mapping the official API can't provide

Instagram's official Graph API has no concept of public account suggestions — it exposes nothing resembling a similar-accounts graph for arbitrary users. The YepAPI Similar Accounts API surfaces the related-profile suggestions for any seed username, so competitor and influencer discovery from a known anchor becomes possible at all, a capability entirely absent from the official API.
