The open infrastructure for reputation management. Send trust events from any application — POS, website, mobile app, HRMS, marketplace — and build verifiable reputation scores for every entity.
A universal, open API for trust and reputation scoring. Like sending analytics events — but for trust.
Like CIBIL, but for everything. A single score from 0–1200 that works across commerce, employment, freelancing, social media, and more. One identity, one reputation.
8 role adapters — Buyer, Seller, Employer, Worker, Freelancer, Organiser, Influencer, Investor. The same entity builds different reputation profiles for each role.
Statistical confidence bounds (Wilson Lower Bound, Beta shrinkage), time-decay weighting, and anti-gaming protection. Not just a number — a mathematically defensible score.
From integration to scored reputation in minutes, not months.
Add our SDK or REST API to your application. Five lines of code to start sending trust events.
const ote = new OpenTrustEngine({
apiKey: 'ote_live_k3x...'
});
await ote.recordEvent({
entityType: 'user',
entityId: 'usr_8f2a...',
eventType: 'order_completed',
role: 'buyer',
rawValue: 1
});
Every transaction, payment, review, delivery, and dispute becomes a trust event. Processed in real-time.
Our 5-pillar statistical model computes trust scores with confidence bounds. No fake scores, no gaming.
Every score is a weighted composite of five measurable dimensions. No black boxes.
Maximum Trust Score — across all five pillars
"CIBIL uses 5 factors for credit. We use 5 pillars for everything else. Same rigor, broader scope."
Same entity, different reputation per role. A user who is a great buyer might be a new seller — and the score reflects both.
Purchase completion, payment reliability, dispute history, return behavior
Fulfillment rate, product quality, response time, customer satisfaction
Payment punctuality, contract completion, worker satisfaction, dispute fairness
Attendance reliability, task completion rate, employer ratings, tenure consistency
Delivery quality, deadline adherence, client ratings, revision rate
Event execution quality, attendee satisfaction, scheduling reliability
Engagement authenticity, brand safety score, audience trust, content consistency
Deal completion, communication reliability, portfolio impact, term adherence
Like credit ratings (AAA/BBB), but for everyday commerce. Clear, recognizable, universally understood.
"Like S&P credit ratings for everyday commerce. Recognizable at a glance, backed by data."
Any application that has users and transactions can send trust events. Here is how industries use OpenTrustEngine.
Track buyer and seller reputation across orders, returns, and reviews.
Employee attendance, performance reviews, and contract completion tracking.
Alternative credit scoring via repayment history and default rates.
Engagement authenticity, content quality scoring, and influencer vetting.
Customer loyalty scoring based on transaction frequency and return rates.
Patient appointment adherence, payment reliability, and provider ratings.
Tenant reliability scoring, rent payment history, and landlord ratings.
Driver on-time delivery rates, damage incidents, and customer satisfaction.
Course completion rates, peer review quality, and instructor ratings.
Project delivery quality, deadline adherence, and client satisfaction scores.
Booking reliability, no-show rates, and guest/host reputation.
Order fulfillment reliability, payment terms adherence, and partner ratings.
Verified entities get higher confidence scores and verification badges. Integrate government-issued ID verification to strengthen your trust ecosystem.
Powered by Cashfree SecureID — per-verification pricing
Unlike review systems that can be gamed, our statistical model ensures integrity at every layer.
First 5 transactions carry reduced weight. New accounts cannot instantly inflate scores through burst activity.
A→B→A patterns are detected and dampened. Mutual score inflation between colluding entities is neutralized.
Multiple small orders from the same pair are aggregated. Splitting one purchase into ten does not multiply score gains.
Maximum score change is capped per day and per month. Prevents overnight score manipulation and ensures gradual, organic growth.
Simple REST API, SDKs, webhooks, and comprehensive documentation. Get integrated in minutes.
// npm install @opentrustengine/sdk
import { OpenTrustEngine } from '@opentrustengine/sdk';
const ote = new OpenTrustEngine({
apiKey: process.env.OTE_API_KEY,
environment: 'production'
});
// Record a trust event
const event = await ote.recordEvent({
entityType: 'user',
entityId: 'usr_8f2a91bc',
eventType: 'order_completed',
role: 'buyer',
rawValue: 1,
metadata: { orderId: 'ORD-1234', amount: 2499 }
});
// Get entity trust score
const score = await ote.getScore('usr_8f2a91bc', 'buyer');
console.log(score);
// { score: 847, band: 'A', label: 'Trusted', confidence: 0.89 }
Simple HTTP endpoints for data intake. No complex auth flows. Send events with a single POST request and your API key.
Real-time notifications for score changes, band promotions, badge earned, threshold alerts, and anomaly detection.
Official SDK for JavaScript/Node.js. Python, PHP, Go, and Ruby SDKs coming soon. Type-safe, well-documented.
Data intake is always free. Pay only when you need score verification, reports, and advanced features via OneTrustEngine.
OpenTrustEngine is purpose-built for universal reputation — not a retrofit of existing systems.
