How to run a Instagram hashtag search

TL;DR

To run a Instagram hashtag search, sign up for a free Captapi key, then send one GET request to /v1/instagram/hashtag-search with your input. You get clean JSON back in seconds for 2 credits per call — no OAuth, scraping or platform SDKs. Find public Instagram posts tagged with a hashtag — each result comes with its media, caption, author, and like / comment counts. Flat 2 credits per call.

How to run a Instagram hashtag search (step by step)

1
Get a free API key
Create a free Captapi account (100 credits, no card) and generate an API key from the dashboard.
2
Call the Instagram Hashtag Search API
Send an authenticated GET request to /v1/instagram/hashtag-search with your input. No OAuth, no scraping setup.
3
Read the JSON response
Parse the clean JSON response. Pass cache=true for a free 24h cache hit; default is always fresh.

Frequently asked questions

What does the Instagram Hashtag Search API do?

The Instagram Hashtag Search API lets you search and return matching results from a public Instagram query using one GET request to /v1/instagram/hashtag-search. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the Instagram Hashtag Search API cost?

Each successful call costs 2 credits. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh. Failed or empty results are never charged.

Do I need a Instagram API key or OAuth?

No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, Rumble, Spotify, Kwai, and more. We handle proxies, rate limits, retries, and authentication for you.

Is the Instagram Hashtag Search API suitable for production use?

Yes. It is a stable REST endpoint with predictable JSON and automatic retries. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh. Use it for analytics, monitoring, and content automation.
