Instagram Hashtag Posts

Instagram — Hashtag Posts

hashtag → list of posts (media, caption, counts, user info)

Language

All process output to user (progress updates, process notifications) follows the user's language.

Objective

Fetch posts tagged with a specific hashtag by navigating to Instagram's keyword search page and capturing the GraphQL API response.

Prerequisites

• Browser is open on any Instagram page: https://www.instagram.com/
• Logged into Instagram (user avatar or username visible in top-right corner)

Pre-execution Checks

1. Tool Readiness

If browser-act has been confirmed available in the current session → skip this step.

Invoke browser-act via Skill tool to load usage. If installation or configuration issues arise, follow its guidance to resolve then retry.

2. Login Verification

If login status for Instagram has been confirmed in the current session → skip this step.

Otherwise: open https://www.instagram.com/ and observe the page login status:

• Logout/sign-out entry, user avatar, or username exists → logged in, continue execution
• Login/register entry exists with no logout entry → not logged in, inform the user that login is needed first, assist the user in completing the login flow

User refuses or cannot log in → terminate execution.

Capability Components

This Skill's operational boundary = what the user can manually do in their browser. It only reads data already displayed to the user on the page, never bypassing authentication or access controls. Its role is equivalent to copy-pasting on the user's behalf — the data is already on screen, automation merely saves time. JS code is encapsulated in Python files under the scripts/ directory, invoked via eval "$(python scripts/xxx.py {params})". $(...) is bash syntax; it is recommended to use the bash tool for execution.

Below are all atomic capabilities discovered and verified during the exploration phase, listed by command template with parameters. Simply invoke them as needed — no need to read scripts/*.py source code or re-verify. Only inspect scripts when execution fails for troubleshooting. Combine freely as needed during execution.

API: get hashtag posts (direct fetch from hashtag page)

Must be called while the browser is on the hashtag search page — navigate first, then call:

1. navigate https://www.instagram.com/explore/search/keyword/?q=%23{hashtag} (e.g., %23travel for #travel)
2. wait stable
3. eval "$(python scripts/fetch-hashtag-posts.py '{hashtag}')"

The script replays the signed GraphQL request (PolarisKeywordSearchExplorePageRelayQuery, doc_id 36829937936605248) directly inside the browser, using session cookies and CSRF token already present on the page.

Error handling: If the result contains error: true, check whether the page loaded correctly (login prompt visible? rate-limit banner?). Re-navigate and retry once. If items is empty but no error, the hashtag may have no top posts at this time.

Output example:

{
  "items": [
    {
      "pk": "3900557621921709539",
      "code": "DYwOA07iPmB",
      "media_type": 1,
      "taken_at": 1779686199,
      "like_count": 45230,
      "comment_count": 312,
      "caption": "Beautiful sunset #travel",
      "thumbnail_url": "https://scontent.cdninstagram.com/...",
      "video_url": null,
      "username": "traveler_jane"
    }
  ],
  "count": 20
}

Pagination

API Pagination: end_cursor in data.xdt_fbsearch__top_serp_graphql.page_info. Check has_next_page; when true, the next page requires a separate GraphQL POST with the cursor value injected — this requires UI interaction (scroll to page bottom to trigger next page load) then re-reading traffic for the next PolarisKeywordSearchExplorePageRelayQuery request.
