}

Implementation

The scraper uses Instagram's internal web API endpoint (i.instagram.com/api/v1/users/web_profile_info/) with a standard browser User-Agent and the public Instagram app ID. This is the same endpoint the Instagram web client calls on first page load.

python

class InstagramScraper:
    BASE_URL = "https://i.instagram.com/api/v1"
    APP_ID = "936619743392459"  # Public Instagram web app ID

    async def get_profile(self, username: str) -> dict:
        """Fetch a user's public profile data."""
        ...

    def parse_profile(self, raw_data: dict) -> dict:
        """Extract key information from raw profile data."""
        ...

    async def get_recent_posts(self, raw_profile: dict, limit: int = 12) -> list:
        """Extract recent posts from profile data."""
        ...

Error Handling

Error	Cause	Fix
ValueError: User not found	Username doesn't exist or is misspelled	Verify the handle
PermissionError: Instagram blocked	IP rate-limited or flagged	Use a VPN or residential proxy
HTTP 401	Request rejected	Rotate User-Agent or wait before retrying

Rate Limiting

• Instagram's internal API is not publicly rate-limited, but aggressive scraping triggers IP blocks.
• Add a 2-5 second delay between requests when scraping multiple accounts.
• Private accounts return only public metadata (follower count, bio) but no posts.

Limitations

• Only works on public profiles
• Returns up to 12 most recent posts (Instagram's default page size)
• Does not return Stories, Reels metadata beyond what appears in the timeline grid
• Video view counts are not included in the internal API response

Use Cases

• Competitive analysis: track follower growth over time by running daily
• Influencer vetting: check engagement rate (likes+comments / followers) before partnerships
• Content research: analyze which post formats drive highest engagement for a niche
• Brand monitoring: track competitor posting frequency and content themes
