  Reddit, Threads, plus robust web-page fallback extraction.


  Use when extracting public posts, transcripts, or pages JS-heavy enough to block
  plain fetch (e.g. download YouTube transcript, scrape TikTok comments, listing pages behind anti-bot/Cloudflare). Auto-fallback trigger terms: web_fetch failed, 403, anti-bot, cloudflare, JS-heavy page.

## Preferred entry: call exports.py (don't hand-roll requests)
Ready-made helpers live in `skills/web-crawler/exports.py`. Prefer them over
writing your own `proxied_get`/`proxied_post` calls — they already inject the
proxy credentials, so **there is no API key to find** (don't read
`$SCRAPECREATORS_API_KEY` / `$FIRECRAWL_API_KEY`, don't check `.env`, don't ask
the user).

```python
import sys; sys.path.insert(0, "/data/workspace/skills/web-crawler")
from exports import scrape_markdown, youtube_transcript, sc_get
scrape_markdown("https://example.com/article")          # Firecrawl fallback
youtube_transcript("https://youtube.com/watch?v=ID")     # ScrapeCreators
sc_get("/v1/tiktok/profile", handle="charlidamelio")     # any SC endpoint

from exports import archive_fallback                      # paywall / Firecrawl-403
archive_fallback("https://www.nytimes.com/.../article.html")  # archive snapshot
```

Named wrappers exist for the high-frequency actions (YouTube/TikTok transcript &
video, IG/Twitter/Reddit posts, profiles, Google/Reddit search). For any other
ScrapeCreators endpoint use `sc_get(path, **params)` — it auto-strips leading
`@`/`#` from handles/hashtags. The intent-routing tables below still tell you
*which* endpoint to pass. Pass `caller_id="chat:<thread>"` (or `job:`/`preview:`)
for cost tracking.

## Quick trigger rules (read this first)
Use this skill immediately when any of these conditions is true:

- `web_fetch` returns HTTP **401/403/429/5xx**
- Response is an anti-bot challenge page (for example Cloudflare "Attention Required", "Just a moment", or challenge/captcha pages)
- The page is JS-heavy and the first fetch misses required detail fields (for example publish time, author, listing code, updated time, price breakdown)
- Search results do not contain the requested field and the value must be extracted from the target page itself

Fallback rule:
- If ordinary fetch is blocked or incomplete, switch to Firecrawl fallback in this skill before asking the user for screenshots/manual text.

## Error signatures -> action
| Signature | Action |
|---|---|
| `web_fetch` HTTP 401/403/429/5xx | Call Firecrawl `POST /v2/scrape` once with `formats:["markdown","links"]` + `onlyMainContent:true` |
| Cloudflare/challenge page text in body | Same Firecrawl call as above |
| Markdown still misses key fields | Retry once with `formats:["rawHtml"]` |
| **Firecrawl itself returns 403 / empty** (hard paywall: NYT, WSJ, Economist, FT, Bloomberg) | Call `archive_fallback(url)` — recovers full text from a web archive snapshot |

### Paywall / Firecrawl-blocked fallback chain (use `archive_fallback`)
When Firecrawl can't get the page either (it returns 403, or markdown comes back
empty) the site is behind a hard paywall or aggressive WAF. Do NOT keep retrying
Firecrawl. Recover the article from a **web archive snapshot** instead:

```python
from exports import archive_fallback
res = archive_fallback("https://www.nytimes.com/.../article.html")
res["markdown"]      # full text, or "" if no snapshot exists anywhere
res["source"]        # "archive.today" | "wayback" | None
res["snapshot_url"]  # the snapshot that was scraped
```

How it works (and why this order):
- **archive.today first** (`archive.ph` / `archive.is` mirrors). User-triggered,
  real-browser captures; historically preserves full text *behind* paywalls.
  Best bet for NYT/WSJ/Economist. We scrape its `/newest/` snapshot via Firecrawl
  (archive.today has its own Cloudflare, so scrape it through Firecrawl, never
  `web_fetch` it directly).
- **Wayback Machine second** (`archive.org`). Automated crawler that *honors*
  robots.txt and paywalls, so it often has NO full text for hard paywalls — but
  it's a good fallback for ordinary 403/Cloudflare pages that aren't paywalled.

Limitation: archives only return text **someone already saved**. If
`res["markdown"] == ""`, no snapshot exists — stop, tell the user, and try the
outlet's official API/RSS or a different source. Do not fabricate the article.

## 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.

**Auth:** No user-supplied key needed. sc-proxy injects the Firecrawl credential automatically when you call through `core.http_client.proxied_post` — just send the request. Do NOT read `$FIRECRAWL_API_KEY` from env, do NOT check `.env` for it, and do NOT ask the user for a Firecrawl key if it looks unset; that env var is intentionally not required. The same proxy-injection model as ScrapeCreators applies here.

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`

- **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.**

```python
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:

```bash
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)

No Firecrawl API key required — sc-proxy injects it. Don't look it up in `.env` or ask the user. Just call:

```python
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.
