Automated MAP Compliance & Buybox Tracking Across 18 Marketplaces

The Engineering Challenge

A leading consumer lifestyle brand suffered significant margin erosion due to over 400 unauthorized third-party marketplace sellers undercutting Minimum Advertised Price (MAP). Internal Python scripts regularly failed due to Amazon & Walmart CAPTCHAs, missing over 65% of daily price fluctuations.

Crawlexa Solution Architecture

Crawlexa deployed a distributed proxy orchestration mesh covering Amazon US/UK/DE, Walmart, and Target. Pipelines run automated hourly scrapes across 45,000 SKUs, capturing seller IDs, fulfillment methods (FBA vs. FBM), stock levels, and instant screenshot evidence when MAP violations occur.

Native Mobile App Scraping & Real-Time Inventory Telemetry

The Engineering Challenge

A hyper-growth delivery platform needed competitor pricing, localized dark store stock, and delivery time estimates. Crucially, the target data was accessible exclusively through native mobile iOS & Android applications with strict TLS cert-pinning, custom HMAC headers, and device attestations.

Crawlexa Solution Architecture

Crawlexa engineers reverse-engineered the target mobile RPC protocol, deploying emulated ARM Android environments that automatically renew ephemeral sessions, compute cryptographic payload hashes, and bypass bot protection without physical device overhead.

Alternative Real Estate & Public Financial Signals Ingestion

The Engineering Challenge

An investment fund required clean, longitudinal listing trends, price revisions, and days-on-market signals across 50 regional property listing databases protected by Cloudflare Turnstile and DataDome WAF rules.

Crawlexa Solution Architecture

Crawlexa established an automated batch crawler with schema normalization, deduplicating records via MinHash algorithms and delivering Parquet files directly to AWS S3 buckets with complete audit logs and cryptographic checksums.
