name: oxylabs-web-unblocker description: Bypasses anti-bot protections using Oxylabs Web Unblocker, an AI-powered proxy that handles fingerprinting, JavaScript rendering, and retries automatically. Use when the user needs to scrape protected websites, bypass CAPTCHAs, access blocked content, or when regular proxies fail due to anti-bot measures.

Oxylabs Web Unblocker

AI-powered proxy solution that automatically manages fingerprinting, headers, retries, and JavaScript rendering.

Endpoint

https://unblock.oxylabs.io:60000

Authentication

HTTP Basic Auth via proxy credentials:

curl -k -x "https://unblock.oxylabs.io:60000" \
  -U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
  "https://example.com"

Quick Start

Basic request:

curl -k -x "https://unblock.oxylabs.io:60000" \
  -U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
  "https://ip.oxylabs.io/headers"

With JavaScript rendering:

curl -k -x "https://unblock.oxylabs.io:60000" \
  -U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
  -H "x-oxylabs-render: html" \
  "https://example.com/spa-page"

Headers

Header	Description
`x-oxylabs-render`	`html` for rendered HTML, `png` for raw PNG bytes; empty value disables automatic forced rendering
`X-Oxylabs-Session-Id`	Reuse same IP across requests (any random string)
`X-Oxylabs-Geo-Location`	Target country, city/state, ZIP/postcode, or coordinates
`x-oxylabs-force-headers: 1`	Enable custom header passthrough
`x-oxylabs-force-cookies: 1`	Enable custom cookie passthrough
`X-Oxylabs-Successful-Status-Codes`	Define custom success codes to prevent retries
`x-oxylabs-browser-instructions`	JSON-escaped browser actions; requires `x-oxylabs-render: html`

Session Persistence

Reuse the same IP across multiple requests:

curl -k -x "https://unblock.oxylabs.io:60000" \
  -U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
  -H "X-Oxylabs-Session-Id: my-session-123" \
  "https://example.com/page1"

Geo-Location Targeting

curl -k -x "https://unblock.oxylabs.io:60000" \
  -U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
  -H "X-Oxylabs-Geo-Location: Germany" \
  "https://example.com"

Use values such as Germany, 90210, California,United States, New York,New York,United States, or lat: 40.7128, lng: -74.0060, rad: 50.

Use normal HTTP methods and request bodies through the proxy; Web Unblocker supports both GET and POST.

When to Use Web Unblocker vs Regular Proxies

Scenario	Use
Sites with anti-bot protection	Web Unblocker
CAPTCHAs, fingerprint detection	Web Unblocker
JavaScript-heavy SPAs	Web Unblocker with `x-oxylabs-render: html`
Simple requests, no protection	Regular Proxies
High volume, price sensitive	Regular Proxies

Key Guidelines

Always use -k flag (or disable SSL verification) - the proxy uses its own certificates
Add x-oxylabs-render: html if experiencing empty content or low success rates; set client timeouts near 180 seconds for rendered requests
Check X-Oxylabs-Final-Url in response headers when redirects matter
Avoid adding custom unblocking headers that may interfere with the AI
Browser instruction header values must be JSON-escaped and compact; pair them with x-oxylabs-render: html
