Summarize Instagram hashtag content ideas with BeatAPI Social Data and GPT

Quick overview

This manual workflow pulls public Instagram posts for a given hashtag using BeatAPI Social Data, extracts up to 12 captioned posts as evidence, and sends them to a BeatAPI chat completion model to generate a cited content-idea brief.

How it works

1. Runs when you manually execute the workflow.
2. Sets the target Instagram hashtag keyword and the BeatAPI text model to use.
3. Calls BeatAPI Social Data to fetch public Instagram hashtag posts in full view.
4. Extracts up to 12 identifiable posts (captions plus post IDs/URLs) and stops with an error if no usable results are returned.
5. Sends the sampled post evidence to the BeatAPI chat completions API to identify repeated content angles and provide cited examples.
6. Returns the generated content brief along with source metadata and BeatAPI request IDs.

Setup

1. Create a BeatAPI API key and add an n8n HTTP Header Auth credential with Authorization: Bearer <your_key>, then select it in both BeatAPI HTTP Request steps.
2. Set the keyword value to the Instagram hashtag you want to analyze (without #) and choose a BeatAPI text model available to your account.
3. Run the workflow manually and review the cited post IDs/URLs before using the brief, since it is based on a limited sample (up to 12 posts).
