Template-specific contract
Each selected version or environment exposes the structure expected by its bindings.
Data validation
Catch invalid document data before rendering a PDF
Inspect the selected template contract and validate request data without spending time on a render that cannot succeed.
How it helps
Keep application payloads aligned with document templates
Validation-only endpoint
Check a payload independently from PDF generation.
Structured errors
Return actionable schema failures to application code and test suites.
Preflight batch items
Validate all items before durable batch jobs are created.
Safer promotions
Test payload fixtures against a staging template before moving it to production.
Clear ownership
Keep calculations in application code and presentation bindings in the document template.
Start with a real document
Create a template and generate your first PDFs without a credit card.
