What it does.
ValidaSign is a pay-per-document e-signature platform that eliminates subscription fatigue. Upload a PDF, add signers, and send — ValidaSign embeds a cryptographically-secured audit record onto every page the moment a signature is applied.
No subscriptions, no complicated setup, no templates to configure. Available in English and Spanish with a full Partner API for white-label integration.
Key features.
Built for operators who need speed without sacrificing rigor.
Cryptographic Audit Trail
Every signed page includes a tamper-evident security stamp with signer identity, IP address, timestamp, and certificate hash.

Supports ordered signing workflows — each signer is notified automatically when it's their turn.
Partner API
RESTful API at /api/public/v1/ for server-to-server document dispatch, status polling, and download. Built for platform integrations.
Bilingual Platform
Full English and Spanish versions with independent SEO — every public page, blog post, and legal document in both languages.
