Introduction

To reward or loyalize users for their social activity, a business needs two different kinds of proof: private, account-level attributes that only the account owner can access — like ownership, audience, and sponsored posts — and public activity that's already visible on a post, like comments, likes, and views. vlayer is the only provider of both: Vouch verifies the private side, and the Social Data API looks up the public side.

Vouch

Vouch is vlayer's end-user-facing verification product. A user logs into their own social account so Vouch can cryptographically confirm private, account-level attributes — ownership, account age, activity, audience demographics, and sponsored posts — straight from the platform's own data. Each redirect starts a verification attempt; a successful verification returns the confirmed data to your webhook, with no screenshots, no manual review, and nothing an AI-generated screenshot or inflated metric can fake.

Screenshots are easy to forge, and platform APIs limit what you can read. Vouch takes a different route:

• Any social platform: Verify data from any account a user can log into online.
• Zero integration: No platform API keys or partnership agreements required.
• Privacy-first: Users control their accounts; you receive only verified proofs.
• Two verification modes: The standard cryptographic web-proof flow by default, or AI-reviewed video verification for sources that can't be notarized.

Use it to vet creators, enable community access, and reduce fraud. See implementation example →

Social Data API

Server-side data lookup — a separate vlayer offering, not part of Vouch. No end-user redirect or login required — call the API directly to pull publicly available attributes about a given post, reel, or story on Instagram or TikTok: comments, likers, metrics, and creator profiles. Use it to confirm that a specific handle commented on or liked a post, then reward the user from a webhook. Start with the overview →

2. Configure your workflow - Define the verifications you need and customize them to your requirements.
3. Integrate with a single API call - Drop our lightweight API or widget into your app. Most customers are live within days.
4. Receive verified data - Verify webhook requests, validate and process outputs, and optionally verify the cryptographic presentation for auditability or third-party use.

Real-World Examples

See how verified social data fits into real products:

• Creator marketplaces: A marketplace validates an influencer's reach and audience demographics straight from their Instagram account. See example →
• Brand partnerships: A brand confirms a sponsored post is live on the creator's account before releasing payment.
• Community access: A community platform admits members only after they prove ownership of an active social account.

Platform Availability

Vouch operates seamlessly across multiple end-user platforms to maximize accessibility and adoption. The platform supports three distinct verification flows to accommodate different user contexts: desktop, mobile, and cross-device.

Desktop Applications

The Vouch Verifier browser extension enables desktop verification workflows within existing web applications. The extension is available on Chrome, Brave and Edge.

Mobile Applications

The native Vouch Verifier iOS and Android applications provide optimized mobile verification experiences. Users on mobile devices complete verification using their device's native capabilities and return seamlessly to your application.

Cross-Device Applications

Desktop users can initiate verification by scanning a QR code with their mobile device, leveraging mobile-specific verification capabilities while starting the process on desktop.
