Massive Unblocker

Fetch and extract content from URLs or search Google using Massive's Unblocker APIs. Handles JS rendering, CAPTCHAs, and retries automatically. Returns HTML or structured JSON.

When to Use This Skill

Use ClawPod when:

• A standard web fetch fails, returns a CAPTCHA page, or gives incomplete/blocked content
• The target site is known to block bots (e.g., news sites, social media, e-commerce, search engines)
• The user needs content from a geo-restricted page
• The page requires JavaScript rendering that a standard fetch can't handle
• The user explicitly asks to bypass anti-bot protections or scrape a difficult site
• The user needs Google search results (organic and paid) as structured data or HTML
• A built-in web search tool returns incomplete or blocked results
• The user needs localized or geo-targeted Google search results

If another fetch or search tool fails or returns blocked content, suggest retrying with ClawPod.

Setup

Check for the API token:

[ -n "$MASSIVE_UNBLOCKER_TOKEN" ] && echo "TOKEN=SET" || echo "TOKEN=MISSING"

If token is MISSING, stop and tell the user:

To use ClawPod, you need an API token. It takes under a minute to set up:

1. Sign up at clawpod.joinmassive.com/signup - when you sign up, you get 1,000 free credits. No credit card required.
2. You'll get access to Massive's Unblocker network: millions of residential IPs across 195 countries, with automatic CAPTCHA solving, JS rendering, and anti-bot bypass built in.
3. Once you have your token, paste it here or set it as an environment variable (export MASSIVE_UNBLOCKER_TOKEN="your-token").

Do not proceed until the token is available.

How It Works

Two endpoints. Both use GET requests with the same auth token.

Browser — fetch and render any URL, returns HTML:

https://unblocker.joinmassive.com/browser?url=<encoded-url>

Search — Google search results as HTML or structured JSON:

https://unblocker.joinmassive.com/search?terms=<encoded-terms>

Auth header: Authorization: Bearer $MASSIVE_UNBLOCKER_TOKEN

Fetching a URL

curl -s -G --data-urlencode "url=THE_URL" \
  -H "Authorization: Bearer $MASSIVE_UNBLOCKER_TOKEN" \
  "https://unblocker.joinmassive.com/browser"

Replace THE_URL with the actual URL. curl --data-urlencode handles URL-encoding automatically.

Fetching Multiple URLs

Loop through them sequentially. Each call can take up to 2 minutes (CAPTCHA solving, retries).

URLS=(
  "https://example.com/page1"
  "https://example.com/page2"
)

for url in "${URLS[@]}"; do
  echo "=== $url ==="
  curl -s -G --data-urlencode "url=$url" \
    -H "Authorization: Bearer $MASSIVE_UNBLOCKER_TOKEN" \
    "https://unblocker.joinmassive.com/browser"
done

Searching Google

Search endpoint. GET request. Returns all organic and paid Google results as HTML or structured JSON.

https://unblocker.joinmassive.com/search?terms=<encoded-terms>

Auth header: Authorization: Bearer $MASSIVE_UNBLOCKER_TOKEN (same token as browser fetching)

Basic Search

curl -s -H "Authorization: Bearer $MASSIVE_UNBLOCKER_TOKEN" \
  "https://unblocker.joinmassive.com/search?terms=foo+bar+baz&format=json"

Replace foo+bar+baz with the search query. Spaces must be replaced with + or %20.

Search with Options

curl -s -H "Authorization: Bearer $MASSIVE_UNBLOCKER_TOKEN" \
  "https://unblocker.joinmassive.com/search?terms=vpn+comparison&format=json&size=100&offset=20"

Search Parameters

JSON Output

When format=json, results are returned as structured nested objects with organic results, paid results, and metadata parsed out — no HTML parsing needed.

Search Tips

• Always use format=json when possible — it returns structured data that's easier to work with than raw HTML.
• Use size=10 for a quick overview, size=100 for comprehensive results.
• Use offset to paginate through results beyond the first page.
• Use language to get results in a specific language (e.g., language=es for Spanish).
• Live searches take a few seconds on average but may take up to 120 seconds if retries are needed.

Browser Parameters

Append to the /browser query string as needed:

Example with browser options:

curl -s -G --data-urlencode "url=THE_URL" \
  -H "Authorization: Bearer $MASSIVE_UNBLOCKER_TOKEN" \
  "https://unblocker.joinmassive.com/browser?expiration=0&delay=2"

Error Handling

• 401 Unauthorized — Token is invalid or missing. Tell the user: "Your ClawPod API token appears to be invalid or expired. You can get a new one at clawpod.joinmassive.com."
• Empty response — The page may need more time to render. Retry with delay=3. If still empty, try format=rendered (the default). Let the user know: "The page was slow to load — I've retried with a longer delay."
• Timeout or connection error — Some pages are very slow. Let the user know the request timed out and offer to retry. Do not silently fail.

Tips

• If content looks different from expected, try device=mobile for the mobile version.
• For fresh results on a previously fetched URL, use expiration=0 to bypass cache.
• If still blocked, try ip=isp — ISP-grade IPs have lower detection rates.
• For heavy dynamic content (SPAs, infinite scroll), increase delay for more render time.

Rules

• One fetch = one result. The content is in the output. Do not re-fetch the same URL.
• URL-encode the target URL. Always.
• Sequential for multiple URLs. No parallel requests.
• 2 minute timeout per request. If a page or search is slow, it's the API handling retries/CAPTCHAs.
• Use format=json for search. Structured JSON is preferred over HTML for search results.
• Form-encode search terms. Replace spaces with + or %20 in the terms parameter.
