Web crawler

All-in-one scraping skill. Routes requests to the best backend automatically — the user does not need to know which API is used.

Use this when:

• Normal web_fetch fails, returns boilerplate, or a site blocks basic fetching
• The user asks for YouTube video content/transcript
• The user wants to scrape, fetch, or extract data from any social media platform
• The user mentions social media profiles, posts, comments, transcripts, ads, trending content, or engagement metrics

Prefer native web_fetch first for simple pages; paid fallback calls should be deliberate and scoped.

What each service is for

ScrapeCreators — Social media data extraction (27+ platforms)

Use for any request involving social media profiles, posts, videos, comments, transcripts, search, ads, trending content, or engagement metrics. Covers TikTok, Instagram, YouTube, LinkedIn, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, Snapchat, Twitch, Kick, Truth Social, TikTok Shop, Google search, and link-in-bio services (Linktree, Komi, Pillar, Linkbio, Linkme, Amazon Shop).

Base URL: https://api.scrapecreators.com Auth: No user-supplied key needed. sc-proxy injects platform credentials automatically — just send the request. The x-api-key header can be any value or omitted entirely. Do NOT bail out or ask the user for a key if $SCRAPECREATORS_API_KEY looks unset; that env var is intentionally not required. Method: All endpoints use GET requests with query params. Responses are JSON.

Firecrawl — Fallback web page scraper

Only a fallback crawler for one web page when ordinary fetching fails. Use POST /v2/scrape with a single url and focused formats like markdown, html, rawHtml, links, summary, or constrained json/question/highlights extraction.

Do not use Firecrawl crawl/map/search/agent/browser endpoints. Do not request screenshots, audio, branding, images, or browser actions unless the proxy policy is expanded later.

ScrapeCreators — Intent routing

Map user intent to the right endpoint. Endpoint paths use the pattern /v1/platform/action.

Important: After selecting an endpoint from the tables below, fetch its OpenAPI spec at https://docs.scrapecreators.com/{path}/openapi.json for full parameter details, types, and example response before making the actual API call. For example: https://docs.scrapecreators.com/v1/tiktok/profile/openapi.json

Profiles / User Info

Posts / Content Feeds

Single Post / Video Details

Comments

Transcripts

Search

Ad Libraries

Trending / Popular

Followers / Following / Live (TikTok only)

TikTok Shop

Link-in-Bio / Other

ScrapeCreators pagination

Paginated endpoints return a cursor/token in the response. Pass it back as a query param to get the next page.

ScrapeCreators known limitations

• Handles: pass without the @ symbol. Use charlidamelio not @charlidamelio. Applies to TikTok, Instagram, Twitter, Threads, Bluesky, Snapchat, Twitch, Pinterest, Truth Social
• YouTube handles: pass without the @ symbol. Use ThePatMcAfeeShow not @ThePatMcAfeeShow. You can also pass a channelId or full URL instead
• Hashtags: pass without the # symbol. Use fyp not #fyp. Applies to TikTok and YouTube hashtag search endpoints
• Twitter: returns ~100 most popular tweets, not chronological/latest
• Threads: only last 20-30 posts visible publicly
• Facebook posts: only 3 posts per page (API limitation)
• Facebook group posts: only 3 posts per page (same limitation)
• LinkedIn company posts: max 7 pages
• Instagram play counts: IG-only views (excludes cross-posted FB views)
• Truth Social: only prominent users (Trump, Vance, etc.) work publicly
• Transcripts: all transcript endpoints require video under 2 minutes
• Reddit subreddit names: case-sensitive! Use "AskReddit" not "askreddit"

Access patterns

ScrapeCreators (social media)

Use Python with core.http_client.proxied_get so sc-proxy injects credentials and bills correctly. Include a typed SC-CALLER-ID header (chat:, job:, preview:, etc.) for cost tracking. Do not read `$SCRAPECREATORS_API_KEY` from env and do not ask the user for a key — the proxy handles it.

from core.http_client import proxied_get
headers = {"SC-CALLER-ID": "chat:youtube-transcript"}
transcript = proxied_get(
    "https://api.scrapecreators.com/v1/youtube/video/transcript",
    params={"url": "https://www.youtube.com/watch?v=VIDEO_ID", "language": "en"},
    headers=headers,
    timeout=20,
).json()

Bash/curl works too (proxy is transparent), but Python is preferred for cost tracking:

curl -s "https://api.scrapecreators.com/v1/tiktok/profile?handle=charlidamelio" \
  -H "x-api-key: any"

Each endpoint has its own OpenAPI spec at https://docs.scrapecreators.com/{path}/openapi.json. Always fetch the per-endpoint spec first to get full parameter details before making the actual API call. The full spec is at https://docs.scrapecreators.com/openapi.json (large file — prefer per-endpoint specs).

Common optional params:

• `trim` (boolean): reduces response payload size. Use when you only need key metrics.
• `region` (string): 2-letter country code for proxy location. Does NOT filter by region — just routes through that country's proxy.

Firecrawl (web page fallback via transparent proxy)

from core.http_client import proxied_post
headers = {"SC-CALLER-ID": "chat:web-crawl-fallback"}
page = proxied_post(
    "https://api.firecrawl.dev/v2/scrape",
    json={
        "url": "https://example.com/article",
        "formats": ["markdown", "links"],
        "onlyMainContent": True,
        "timeout": 60000,
    },
    headers=headers,
).json()

Decision rules

Route every request to the right backend. The user should never need to specify which API to use.

Social media request (profile, posts, comments, search, ads, trending, transcripts)

Use ScrapeCreators. Match the user's intent to an endpoint from the routing tables above. Strip @ from handles and # from hashtags before calling. Fetch the per-endpoint OpenAPI spec first for full param details.

YouTube URL or YouTube content request

Use ScrapeCreators for YouTube (channel info, videos, shorts, playlists, comments, transcripts, search, trending shorts). Match the user's intent to the appropriate YouTube endpoint from the routing tables above.

For a YouTube URL, use /v1/youtube/video to get video details and transcript. If the user's goal is content analysis, summarization, quote extraction, or topic mining, the transcript is included in the video response.

For a YouTube topic query, use /v1/youtube/search to find relevant videos, then call /v1/youtube/video only for the videos needed. Avoid fetching many videos by default.

Blocked or JS-heavy web page

Use Firecrawl once with formats:["markdown","links"] and onlyMainContent:true. Treat the returned Markdown as the extraction substrate, not as final truth: parse the title, price/value fields, specs, body description, image URLs, outbound links, and obvious contact/location hints from the page structure.

General web-page extraction lessons:

• Many listing/detail pages render important content with JavaScript, image galleries, hidden sections, or repeated UI labels. web_fetch may return boilerplate while Firecrawl can still recover the real main content.
• Do not hard-code site-specific labels. Convert page text into a generic structured summary: what it is, where it is, key numbers, evidence snippets, media/links, and caveats.
• Preserve source URLs for images and links when they help verify the page, but do not download or batch-process every media asset unless the user asks.
• If Markdown misses important layout or structured fields, retry once with rawHtml; use json, question, or highlights only when the user asked for narrow extraction and the schema/prompt is specific.

Cost discipline

ScrapeCreators — most endpoints cost 1 credit per request. Exceptions: /v1/tiktok/user/audience costs 26 credits; /v1/tiktok/video/transcript with use_ai_as_fallback=true costs +10 credits; /v1/google/company/ads with get_ad_details=true costs 25 credits. Warn users before calling expensive endpoints.

Firecrawl — billed per page plus expensive modifiers.

Keep calls tight: one page, one video, or a small shortlist. Never batch-crawl whole websites or bulk-scrape entire feeds with this skill.

If the proxy returns 403, the request is outside the allowed use case. Change the approach instead of retrying.

If the proxy returns 429, back off; do not parallelize around the limit.

If the upstream returns a failure, report the exact failure and avoid repeated paid retries unless one parameter change is clearly justified.
