Walkthrough

Step 1 — Define the Niche

Ask the user for:

• Niche — what space are they in?
• Platform — Instagram, TikTok, or both?
• Goal — what does performing well mean for them? (views, likes, comments, shares, followers)
• Known competitors — any accounts they already know are doing well?

Step 2 — Search for Top Content

Instagram — search reels by keyword

POST https://api.scrapecreators.com/v2/instagram/reels/search
x-api-key: <SCRAPE_CREATORS_API>

{ "keyword": "[NICHE_KEYWORD]" }

TikTok — search by keyword

POST https://api.scrapecreators.com/v1/tiktok/search/keyword
x-api-key: <SCRAPE_CREATORS_API>

{ "keyword": "[NICHE_KEYWORD]" }

TikTok — search by hashtag

POST https://api.scrapecreators.com/v1/tiktok/search/hashtag
x-api-key: <SCRAPE_CREATORS_API>

{ "hashtag": "[HASHTAG]" }

Collect 10-15 top-performing posts across platforms.

Step 3 — Gather Account Details

For each promising creator, pull their profile:

Instagram

POST https://api.scrapecreators.com/v1/instagram/profile
x-api-key: <SCRAPE_CREATORS_API>

{ "username": "[HANDLE]" }

Then get their recent reels (paginated):

POST https://api.scrapecreators.com/v1/instagram/user/reels
x-api-key: <SCRAPE_CREATORS_API>

{ "username": "[HANDLE]" }

For a specific post's details:

POST https://api.scrapecreators.com/v1/instagram/post
x-api-key: <SCRAPE_CREATORS_API>

{ "url": "[POST_URL]" }

For comments on a post:

POST https://api.scrapecreators.com/v2/instagram/post/comments
x-api-key: <SCRAPE_CREATORS_API>

{ "url": "[POST_URL]" }

TikTok

POST https://api.scrapecreators.com/v1/tiktok/profile
x-api-key: <SCRAPE_CREATORS_API>

{ "username": "[HANDLE]" }

Get a specific video with transcript:

POST https://api.scrapecreators.com/v2/tiktok/video
x-api-key: <SCRAPE_CREATORS_API>

{ "url": "[VIDEO_URL]" }

Step 4 — Analyze Top Content

For each top-performing video, run a VidJutsu watch:

POST https://api.vidjutsu.ai/v1/watch
Authorization: Bearer <VIDJUTSU_API_KEY>

{
  "mediaUrl": "[VIDEO_URL]",
  "prompt": "Analyze this video. Return: hook text, format, pacing, transitions, CTA, tags."
}

Extract from each analysis:

• Hook — what stops the scroll in the first 1-2 seconds?
• Format — talking head, b-roll, slideshow, text overlay, etc.
• Length — optimal duration for this niche
• Transitions — cuts, zooms, speed ramps
• CTA style — how do they drive action?

Step 5 — Build Research Brief

Compile findings into a structured brief:

1. Top hooks — ranked by engagement
2. Winning formats — which content types perform best
3. Posting patterns — frequency, timing, caption styles
4. Content gaps — topics the niche wants but nobody is making
5. Hashtag clusters — 3-5 hashtag groups that drive discovery
6. Platform differences — what works on Instagram vs TikTok (if both were researched)

Present the brief to the user. This informs all content generation.

Key Behaviors

• 10 credits per VidJutsu watch call
• Scrape Creators calls are billed separately via Scrape Creators account
• Always present findings before generating content
• Look for content gaps, not just what's popular — differentiation matters
• Use comments data to understand audience sentiment and unmet needs
