AlterLab Cortex
An autonomous AI system that monitors your scraping infrastructure, diagnoses failures in real-time, and deploys optimizations automatically.
Zero-Touch Optimization
Cortex operates autonomously, continuously improving your scraping success rates without manual intervention.
Detect
Monitor all scraping requests and identify patterns in failures
Diagnose
AI analyzes root causes using ML models and historical data
Optimize
Generate and test multiple solution candidates in parallel
Deploy
Automatically roll out the best-performing strategy
Autonomous Failure Recovery
When a scrape fails, Cortex analyzes the root cause, generates multiple fix strategies, validates them in parallel, and deploys the optimal solution—all without human intervention.
Adaptive Anti-Bot Strategies
Cortex continuously learns from successful and failed attempts, dynamically adjusting browser fingerprints, request patterns, and timing to stay ahead of detection systems.
Cross-Domain Intelligence
Insights learned from one domain automatically improve performance on similar sites. The system builds a knowledge graph of web structures, defense mechanisms, and optimal extraction patterns.
Predictive Optimization
Machine learning models predict which sites are likely to change or implement new protections, proactively testing and adapting strategies before issues arise.
Cortex included in every plan. 5,000 free scrapes to start.
Extract more. Pay less.
Access any website.
Six capabilities that set us apart from every other scraping API.
LLM-Ready Output
Your AI agents waste most of their context window parsing raw HTML. Cortex strips the noise and delivers clean markdown, JSON, or text — up to 70% fewer tokens, zero parsing code.
Cortex AI
A self-learning engine that adapts to every domain. Auto-generates extraction playbooks, learns optimal headers and cookies, and gets smarter with every scrape — zero configuration.
Access Any Website
4-tier escalation from simple HTTP to full stealth penetration. Automatic CAPTCHA solving, residential proxies, and browser fingerprint rotation — 99.9% success rate.
3-Line Integration
One REST endpoint. Three lines of code. No SDKs to install, no OAuth flows to configure. Just POST a URL and get structured data back. Works with any language.
Scale to Millions
Queue thousands of URLs in a single request. Intelligent parallelization with automatic retries. Webhook delivery as results complete — no polling, no infrastructure to manage.
Unbeatable Pricing
5,000 pages per dollar. Competitors charge 5–10x more for the same data. No gotchas, no overages — just honest pricing.
