API-Based Data Extraction
Fast, lightweight data extraction by reverse-engineering mobile app APIs and private web endpoints—extracting clean JSON payloads 10x faster with 90% lower proxy compute costs.
What is API-Based Data Extraction?
Rendering full headless Chrome browsers is slow, resource-heavy, and expensive when scraping millions of records. Many modern websites and mobile applications communicate with underlying REST/GraphQL APIs that return pure JSON.
We inspect network traffic, decrypt mobile app payloads, and reverse-engineer private API endpoints. By querying these endpoints directly using lightweight HTTP clients (HTTPX / cURL-impersonate) and authentic session tokens, we extract millions of records at lightning speed.
Bypasses frontend HTML parsing for 10x faster extraction and pure structured JSON output.
Intercepts and replays mobile API signatures and GraphQL queries.
No heavy browser rendering means minimal CPU, RAM, and proxy data consumption.
What's Included in Every Project
Full-scale data extraction deliverables designed for resilience, clean schema parsing, and scheduled delivery.
Reverse-Engineered API Client Source Code (Python / TypeScript)
Lightweight HTTP scripts querying private REST/GraphQL endpoints directly.
Mobile App Signature & Token Generator
Automated cryptographic request signing and HMAC header generator for mobile APIs.
TLS Fingerprint Impersonation (cURL-impersonate)
Matches authentic browser and mobile TLS handshakes to bypass Cloudflare and Akamai.
Automated Session & Token Refresh Handlers
Keeps authorization bearer tokens active without manual re-authentication.
High-Speed PostgreSQL & S3 Ingestion Hooks
Streams incoming JSON payloads directly into your database or cloud storage.
30-Day Break-Fix Warranty & API Signature Maintenance
Immediate script updates if the target API updates its header signatures.
Our 4-Step Scraping & Data Pipeline Process
Agile crawler engineering with rigorous anti-bot evasion testing.
Network Traffic & API Protocol Audit
We analyze mobile app and web network traffic, identifying endpoints, query parameters, and auth headers.
Signature Decryption & Token Generator Build
We reverse-engineer request signatures, configure TLS-client impersonation, and test raw JSON responses.
