Developer API Documentation

Server-to-server access to SigVerify's Panda verification engine. The Developer API is available through the web platform only and has no free API credits.

Base URL

https://sigverfiy.in/api/v1

Keep your API key on your own backend. Never expose it in browser JavaScript, Android APK/AAB files, or public repositories.

Authentication

Send your secret API key with every request:

X-API-Key: sv_live_YOUR_KEY

Keys are created and managed from the authenticated Developer Portal.

Verify a PDF

POST /verify

Upload one signed PDF. One API credit is consumed after Panda returns a verification result.

curl -X POST /api/v1/verify   -H "X-API-Key: sv_live_YOUR_KEY"   -F "file=@signed-document.pdf"

Panda result

The API returns the same core verification result produced by SigVerify's Panda engine, including signature, certificate, trust and evidence fields when available.

Public API endpoint: https://sigverfiy.in/api/v1. If your hosting layer does not proxy /api/v1 to the backend yet, use the Developer Portal after the backend routing is enabled.
