Frequently Asked Questions

General​

What is Klervex?​

Klervex is a Trade Document Intelligence Platform that automates the creation and validation of international trade documents. Upload source documents, AI extracts the data, deterministic rules validate compliance, and customs-grade PDFs are generated.

Who is Klervex for?​

Freight forwarders, customs brokers, e-commerce exporters, and anyone who needs to create and validate trade documents. Klervex also provides an API for ERP integration and AI agent workflows.

How is Klervex different from other trade document tools?​

Klervex combines AI extraction with deterministic validation. The AI reads your documents, but validation uses real reference data (HS codes, sanctions lists, port codes) and deterministic rules — not AI judgment. This means results are consistent, explainable, and auditable.

Extraction​

What file types are supported?​

PDF, PNG, JPG, TIFF, XLS, and XLSX.

How accurate is the AI extraction?​

Accuracy depends on document quality. High-resolution, machine-generated PDFs typically achieve 90%+ accuracy. Scanned or handwritten documents may have lower accuracy. Every extracted field includes a confidence score so you know what to review.

Can I use Klervex without uploading documents?​

Yes. Click "Start with Empty Form" to enter data manually.

Validation​

What does validation check?​

Eight categories: required fields, HS codes, sanctions, port codes, Incoterms, value consistency, country-specific rules, and document-specific rules. See Validation Rules.

Is validation AI-based?​

No. Validation is entirely deterministic — it uses business rules and reference data (lookup tables). The same data always produces the same result.

How often is reference data updated?​

  • HS codes: quarterly (following USITC/TARIC update cycles)
  • OFAC sanctions: weekly (every Sunday)
  • Port codes: monthly

Documents​

What document types can Klervex generate?​

Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin, Proforma Invoice, Dangerous Goods Declaration, and Air Waybill.

Are the generated documents legally valid?​

Klervex generates documents in the correct format with the correct content. Legal validity depends on your jurisdiction and the specific document. Consult your customs broker or legal counsel.

How does document verification work?​

Every document includes a SHA-256 hash. Anyone can verify the document hasn't been tampered with at klervex.com/verify.

API​

Is there an API?​

Yes. Klervex provides a REST API for all operations: extraction, validation, document generation, and CRUD. See the API Setup guide.

What authentication does the API use?​

API key authentication via Authorization: Bearer <api-key> header.

Pricing​

Is there a free tier?​

Yes. The free tier includes limited extractions, validations, and document generations per day. See Pricing.

How do I upgrade?​
