ANTIDETECT BROWSER API

WHAT IT IS

A cloud-hosted antidetect browser that creates isolated browser sessions with unique fingerprints and auto-allocated mobile proxies. Each session gets its own canvas fingerprint, WebGL hash, font list, screen resolution, timezone, and language — making it impossible to link sessions together.

Built on Camoufox (hardened Firefox fork). Every session automatically includes a mobile proxy from one of 6 countries (US, GB, DE, FR, ES, PL), so your browser traffic routes through a real 4G/5G IP.

Control the browser via HTTP API commands: navigate, click, type, screenshot, extract content. Perfect for web scraping, form automation, testing, and any task that needs a real browser with a clean fingerprint.

PRICING

A typical 30-second scraping session costs ~$0.0025. At 10,000 sessions/day, that's ~$25/day.

HOW TO USE

Step 1: Create a Session

curl -X POST "https://browser.proxies.sx/v1/sessions" \
  -H "Content-Type: application/json" \
  -d '{"country": "US"}'

Returns 402 with payment instructions. Pay USDC, then retry with Payment-Signature header.

Step 2: Send Browser Commands

# Navigate to a page
curl -X POST "https://browser.proxies.sx/v1/sessions/$SESSION_ID/command" \
  -H "X-Session-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "navigate", "url": "https://www.google.com"}'

# Type into a field (human-like speed)
curl -X POST "https://browser.proxies.sx/v1/sessions/$SESSION_ID/command" \
  -H "X-Session-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "type_slow", "selector": "input[name=q]", "text": "mobile proxies"}'

# Click a button
curl -X POST "https://browser.proxies.sx/v1/sessions/$SESSION_ID/command" \
  -H "X-Session-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "click", "selector": "button[type=submit]"}'

# Get page content
curl -X POST "https://browser.proxies.sx/v1/sessions/$SESSION_ID/command" \
  -H "X-Session-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "content"}'

# Take screenshot
curl -X POST "https://browser.proxies.sx/v1/sessions/$SESSION_ID/command" \
  -H "X-Session-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "screenshot"}'

Available Commands

Step 3: Close Session

curl -X DELETE "https://browser.proxies.sx/v1/sessions/$SESSION_ID" \
  -H "X-Session-Token: $TOKEN"

IDENTITY BUNDLES — Long-Term Account Persistence

Identity Bundles let you save and restore a complete browser identity across sessions. One account = one fixed bundle (cookies + fingerprint + proxy device). This is the key to maintaining logged-in accounts for weeks or months without triggering security checkpoints.

What Gets Saved

Workflow: Manage an Account for Months

# Day 1: Create session, log into Twitter, save profile
curl -X POST browser.proxies.sx/v1/sessions \
  -H "Payment-Signature: $TX" -d '{"country":"US"}'
# ... login, do actions ...
curl -X POST browser.proxies.sx/v1/sessions/$ID/profile \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"name":"twitter-main"}'
# → Returns prof_abc123

# Day 30: Create session WITH profile (auto-restores everything)
curl -X POST browser.proxies.sx/v1/sessions \
  -H "Payment-Signature: $TX" \
  -d '{"profile_id":"prof_abc123"}'
# → Same fingerprint, same proxy device, cookies injected
# → Navigate to twitter.com → still logged in

# Save updated profile before closing
curl -X POST browser.proxies.sx/v1/sessions/$ID/profile \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"name":"twitter-main"}'

WHY ANTIDETECT

Modern websites fingerprint your browser to detect automation. They check:

With Camoufox + mobile proxy, each session looks like a unique real user on a real mobile network. Sites like Google, Instagram, LinkedIn, and Amazon see a legitimate visitor — not a bot.
