New install

I tried to install a skill package from Yavira, but the item currently does not return a direct package file. Inspect the source page and any extracted docs, then tell me what you can confirm and any manual steps still required.

Upgrade existing

I tried to upgrade a skill package from Yavira, but the item currently does not return a direct package file. Compare the source page and any extracted docs with my current installation, then summarize what changed and what manual follow-up I still need.

FlareSolverr — Cloudflare Bypass

Use FlareSolverr to bypass Cloudflare protection when direct curl requests fail with 403 or Cloudflare challenge pages.

Setup

Run FlareSolverr (Docker recommended): docker run -d --name flaresolverr -p 8191:8191 ghcr.io/flaresolverr/flaresolverr:latest Set the environment variable: export FLARESOLVERR_URL="http://localhost:8191" Verify: curl -s "$FLARESOLVERR_URL/health" | jq '.' # Expected: {"status":"ok","version":"3.x.x"}

When to Use

Direct curl fails with 403 Forbidden Cloudflare challenge page appears (JS challenge, captcha, "Checking your browser") Bot detection blocks automated requests Rate limiting or anti-scraping measures

Workflow

Try direct curl first (it's faster and simpler) If blocked: Use FlareSolverr to get cookies/user-agent Reuse session for subsequent requests (optional, for performance)

Simple GET Request

curl -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com/protected-page", "maxTimeout": 60000 }' | jq '.'

Response Structure

{ "status": "ok", "message": "Challenge solved!", "solution": { "url": "https://example.com/protected-page", "status": 200, "headers": {}, "response": "<html>...</html>", "cookies": [ { "name": "cf_clearance", "value": "...", "domain": ".example.com" } ], "userAgent": "Mozilla/5.0 ..." }, "startTimestamp": 1234567890, "endTimestamp": 1234567895, "version": "3.3.2" }

Extract Page Content

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com/protected-page" }' | jq -r '.solution.response'

Extract Cookies

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com" }' | jq -r '.solution.cookies[] | "\(.name)=\(.value)"'

Session Management

Sessions allow reusing browser context (cookies, user-agent) for multiple requests, improving performance.

Create Session

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{"cmd": "sessions.create"}' | jq -r '.session'

Use Session for Request

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com/page1", "session": "SESSION_ID" }' | jq -r '.solution.response'

List Active Sessions

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{"cmd": "sessions.list"}' | jq '.sessions'

Destroy Session

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "sessions.destroy", "session": "SESSION_ID" }'

POST Requests

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.post", "url": "https://example.com/api/endpoint", "postData": "key1=value1&key2=value2", "maxTimeout": 60000 }' | jq '.' For JSON POST data: curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.post", "url": "https://example.com/api/endpoint", "postData": "{\"key\":\"value\"}", "headers": { "Content-Type": "application/json" } }' | jq '.'

Custom User-Agent

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com", "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36" }' | jq '.'

Custom Headers

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com", "headers": { "Accept-Language": "en-US,en;q=0.9", "Referer": "https://google.com" } }' | jq '.'

Proxy Support

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com", "proxy": { "url": "http://proxy.example.com:8080" } }' | jq '.'

Download Binary Content

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com/file.pdf", "download": true }' | jq -r '.solution.response' | base64 -d > file.pdf

Common Errors

"status": "error": Request failed (check message field) "status": "timeout": maxTimeout exceeded (increase timeout) "status": "captcha": Manual captcha required (rare, usually auto-solved)

Check Status

curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{"cmd": "request.get", "url": "https://example.com"}' | \ jq -r '.status'

Bypass Cloudflare and Extract Data

# Step 1: Fetch page through FlareSolverr RESPONSE=$(curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{ "cmd": "request.get", "url": "https://example.com/protected-page" }') # Step 2: Check if successful STATUS=$(echo "$RESPONSE" | jq -r '.status') if [ "$STATUS" != "ok" ]; then echo "Failed: $(echo "$RESPONSE" | jq -r '.message')" exit 1 fi # Step 3: Extract and parse HTML echo "$RESPONSE" | jq -r '.solution.response'

Multi-Page Session

# Create session SESSION=$(curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d '{"cmd": "sessions.create"}' | jq -r '.session') # Page 1 curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d "{\"cmd\": \"request.get\", \"url\": \"https://example.com/page1\", \"session\": \"$SESSION\"}" | \ jq -r '.solution.response' # Page 2 (reuses cookies from page 1) curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d "{\"cmd\": \"request.get\", \"url\": \"https://example.com/page2\", \"session\": \"$SESSION\"}" | \ jq -r '.solution.response' # Cleanup curl -s -X POST "$FLARESOLVERR_URL/v1" \ -H "Content-Type: application/json" \ -d "{\"cmd\": \"sessions.destroy\", \"session\": \"$SESSION\"}"

Health Check

curl -s "$FLARESOLVERR_URL/health" | jq '.'

Performance Tips

Use sessions for multiple requests to same domain (reuses cookies/context) Increase maxTimeout for slow sites (default: 60000ms) Fallback to direct curl when possible (FlareSolverr is slower due to browser overhead) Destroy sessions when done to free resources

Limitations

Slower than direct curl (launches headless browser) Resource intensive (limit concurrent requests) May not solve all captchas (most Cloudflare challenges work) HTML only in response (no client-side JS execution after fetch)

Best Practices

Always try direct curl first Use sessions for multi-page workflows Set appropriate maxTimeout (default 60s, increase for slow sites) Clean up sessions when done Handle errors gracefully (check status field) Rate limit your requests (don't overwhelm FlareSolverr or target site)
