Built to protect your data quality, right from your codebase.

import { Cipher } from '@surbee/cipher'
const cipher = new Cipher({
  apiKey: 'sk_live_...',
  tier: 4,
})

Initialize in seconds

Import the SDK, add your API key, and choose a validation tier. That's all you need to get started.

const result = await cipher.validate({
  responses: submission.answers,
  behavioral: tracker.getMetrics(),
  device: tracker.getDeviceInfo(),
})
result.score       // 0.94
result.recommendation // 'keep'

Validate any response

Pass survey responses with behavioral metrics. Get instant quality scores, recommendations, and detailed check results.

const cipher = new Cipher({
  tier: 4,
  thresholds: {
    fail: 0.4,    // Auto-reject below
    review: 0.7, // Flag for review
  },
  checks: {
    aiContent: true,
    vpnDetection: true,
  }
})

Custom thresholds & checks

Set your own score thresholds for auto-reject and review. Enable or disable specific checks like AI detection or VPN blocking.

// Validate multiple responses at once
const results = await cipher.validateBatch(
  responses,
  { parallel: 10 }
)
// Cross-respondent fraud detection
const rings = await cipher.detectFraudRings(
  projectId
)

Batch & fraud ring detection

Validate hundreds of responses in parallel. Detect coordinated fraud rings across your entire dataset with cross-respondent analysis.
