Research Instagram hashtags with real post-volume data

The YepAPI Instagram Hashtag API resolves a tag name into hard numbers — its media_count (total posts using it) plus a search_results array of related hashtags, each with their own counts. A POST to /v1/instagram/hashtag turns hashtag guesswork into data, sizing volume and competition before you build a content strategy around a tag.

It is the topical-discovery member of the YepAPI Instagram suite, complementing the user-centric endpoints: where Search and Similar Accounts find people, Hashtag finds topics. Pair related-tag results with the User Posts API to study top creators in a niche. One key also covers TikTok, YouTube, SEO, and AI, so cross-platform tag research stays a single integration.

What is an Instagram hashtag API?

An Instagram hashtag API resolves a tag name into structured data about its usage. You send {"hashtag": "travel"} and receive the tag's media_count — how many posts have ever used it — alongside a search_results array of related hashtags, each with its own post count, and the tag's top-performing posts. Rather than typing a tag into the app and eyeballing whether it is crowded, you get exact volume numbers you can compare across tags. It is the foundational tool for hashtag research: sizing reach potential, judging competition, and discovering adjacent tags programmatically.

Build your own Instagram hashtag-research tool

Use the Hashtag endpoint to power a content-strategy planner that ranks tags by media_count, finds lower-competition alternatives from the related-tag results, or assembles an optimal hashtag set for a campaign. Because every tag returns a precise post count, you can balance high-volume reach against niche specificity quantitatively. Expand a seed tag into a whole cluster via search_results, then study who performs under each tag using the YepAPI User Posts and Post APIs.

Instagram Hashtag API pricing — $0.01 per call

Each hashtag lookup is a flat $0.01, no tiers or minimums. Researching hundreds of tags to build a content calendar costs only a few dollars, and the spend shares one balance with every YepAPI endpoint. You pay per call only, so hashtag research scales with the breadth of your strategy rather than a subscription tier.

Hashtag volume the official API restricts

Instagram's official Graph API allows hashtag lookups only for business accounts and caps them at a small number of unique tags per rolling window, severely limiting research. The YepAPI Hashtag API returns post counts and related tags for any hashtag on demand, with no business-account requirement, so you can research as many tags as your strategy needs — well beyond the official API's tight quotas.

Try the Instagram Hashtag API free

Sign up for $5 in free credit, no card required. That is 500 hashtag lookups — enough to research an entire content calendar's worth of tags before you pay anything.
