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 scraping setup required.

How many credits does the Instagram Hashtag Search API cost?

Each successful call costs 12 credits. Responses are cached for 24 hours, and cached results cost 0 credits. Failed or empty results are never charged.

Do I need a Instagram API key or OAuth?

No. A single Captapi key works across YouTube, TikTok, Instagram, and Facebook. 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, automatic retries, and a shared 24-hour cache. Use it for RAG pipelines, analytics, monitoring, and content automation.
