Stealth Levels

Basic (Fastest)

Best for sites with minimal bot detection

User-Agent randomization
Basic header manipulation
Cookie handling
~1-2 second delay

Medium (Recommended)

Balanced stealth and performance

Full fingerprint randomization
Canvas/WebGL fingerprint masking
Timezone and language spoofing
Human-like scrolling and movements
~3-5 second delay

Advanced (Slowest)

Maximum stealth for heavily protected sites

All medium features plus:
WebDriver detection evasion
Bot-specific JavaScript challenge bypass
Advanced TLS fingerprinting
Mouse movement simulation
Random click patterns
~8-12 second delay

Field Descriptions

data.detectionBypassedWhether bot detection was successfully evaded

data.fingerprintBrowser fingerprint used for this request

Error Handling

Detection Failed (403 Forbidden)

Bot detection couldn't be bypassed. Try increasing stealth level or enable proxy rotation.

CAPTCHA Required (429 Too Many Requests)

Site presented a CAPTCHA challenge. Contact support for CAPTCHA solving integration.

Invalid Operation (400 Bad Request)

Operation must be one of: fetch, scrape, or screenshot.

Timeout Error (500 Internal Server Error)

Stealth mode timed out. Site may be too slow or heavily protected.

Pro Tip: Start with "medium" stealth level. Only use "advanced" for sites that block medium level. Stealth mode adds 8-15 seconds of processing time—plan accordingly for batch operations.
