Automating Hardware Audits via REST API: Python & cURL Guide for ITADs and Resellers
Integrate multi-brand warranty verification and hardware spec decoding directly into your warehouse management (WMS) or ERP system with our unified REST API.

Why In-House Scrapers Fail & The Need for a Unified Hardware API
Many IT asset disposition (ITAD) firms and electronics resellers initially try building custom web scrapers to check warranties on vendor portals. Within weeks, these scripts break due to:
- Enterprise Web Application Firewalls (WAF): Akamai Bot Manager, Cloudflare Turnstile, and PerimeterX actively block headless browsers and rotating proxies.
- Incompatible Brand Schemas: Lenovo requires 8-character serials and MTM codes; Dell uses 7-character Service Tags; HP requires both Serial Number and Product Number (-#ABA); Apple requires 10–12 alphanumeric characters.
- Constant DOM & API Churn: Vendor frontend updates frequently invalidate CSS selectors and undocumented internal API endpoints.
CheckWarranty replaces this fragile maintenance overhead with a single, highly available Unified REST API that standardizes warranty and hardware specs across all major brands into a predictable JSON schema.
Authentication & API Key Configuration
All API requests authenticate using standard Bearer Token authorization. You can generate production and sandbox API keys directly in your Developer Dashboard.
unknown nodeQuickstart: Checking a Single Device via cURL
To verify a single serial number (with brand auto-detection enabled), issue a POST request to /api/v1/scan/single:
The API responds with a structured JSON object containing normalized warranty dates, entitlement tier, and parsed hardware specifications:
unknown nodeProduction Integration: Python Script for Bulk Warehouse Ingestion
In high-volume warehouse environments, you can submit batches of up to 500 serials at once and poll for completion asynchronously:
unknown nodeZero-Risk Billing SLA & HP Product Number Recovery
Our API is built specifically for enterprise warehouse workflows:
- Zero-Risk Credit SLA: Credits are deducted only when a verified entitlement record is returned. If a serial number is invalid or cannot be found, the item returns a 404 status with exactly 0 credits charged.
- Automatic HP PN Recovery: HP queries typically require a Product Number (e.g., 20J39UT#ABA). If omitted, our engine performs automated reverse PN resolution without failing the lookup.
- Webhooks & Streaming: Receive real-time HTTP callbacks upon batch completion to trigger downstream ERP grading workflows automatically.
