Your first ZKScore integration in 5 minutes Manage API keys and authentication Build trust-gated applications Real-time event notifications Become an attestation provider Deploy across multiple networks ## Quick Start Path Create your API key in the [Builder Portal](https://builder.onzks.com) [API Keys Guide →](/guides/api-keys) Add ZKScore SDK to your project [Getting Started →](/guides/getting-started) Mint your first ZKScore identity [Identity Guide →](/guides/using-zks-ids) Add trust and reputation to your app [Trust Gating →](/guides/trust-gating) ## Integration Patterns ### Score-Gated Applications Control access based on reputation scores: ```typescript theme={null} import { ZKScoreSDK } from '@zkscore/sdk'; const sdk = new ZKScoreSDK({ apiKey: 'your-key' }); async function checkAccess(userAddress: string, minScore: number) { const score = await sdk.scores.getScore(userAddress); return score.overall >= minScore; } // Gate premium features if (await checkAccess(userAddress, 700)) { showPremiumContent(); } else { showUpgradePrompt(); } ``` ### Achievement Systems Gamify user engagement with achievements: ```typescript theme={null} // Track user progress const progress = await sdk.achievements.getProgress(userAddress, 'defi-expert'); // Show progress bar // Claim when eligible if (progress.completed) { await sdk.achievements.claim({ achievementId: 'defi-expert' }); } ``` ### Privacy-Preserving Verification Use zero-knowledge proofs for private verification: ```typescript theme={null} // Generate proof without revealing exact score const proof = await sdk.zkProofs.generate({ address: userAddress, type: 'score-threshold', threshold: 700, hideExactScore: true, }); // Verify on server const isValid = await sdk.zkProofs.verify(proof); ``` ### Trust Systems Build custom trust frameworks with attestations: ```typescript theme={null} // Create KYC attestation await sdk.trustLayer.createAttestation({ subject: userAddress, schema: 'kyc-verification', data: { verified: true, level: 'tier-2', provider: 'Synaps', }, }); // Check trust requirements const evaluation = await sdk.trustLayer.evaluatePolicy(userAddress, { rules: [ { schema: 'kyc-verification', required: true, conditions: { 'data.verified': true }, }, ], }); ``` ## Common Use Cases Undercollateralized loans based on reputation Exclusive NFT access for high-reputation users Weighted voting based on expertise Trust-based social interactions Anti-sybil systems and player rankings Seller reputation and buyer protection ## Platform-Specific Guides ### Web Applications React hooks and components Next.js integration guide Vue.js application setup Angular framework integration ### Mobile Applications Mobile app integration Flutter SDK integration Swift/iOS integration Kotlin/Android integration ### Backend Services Node.js server integration Python backend integration Go server integration PHP application integration ## Advanced Topics Build custom reputation algorithms Advanced privacy features Optimize with batch processing Advanced webhook configurations ## Best Practices ### Security Never expose API keys in client-side code Always validate user inputs Implement comprehensive error handling Respect API rate limits ### Performance Cache frequently accessed data Combine multiple API calls Load data only when needed Update UI before API confirmation ### User Experience Show loading indicators Provide clear error feedback Graceful degradation Ensure inclusive design ## Troubleshooting ### Common Issues **Problem**: Getting 401 Unauthorized errors\ **Solution**: Verify your API key is correct and active in the [Builder Portal](https://builder.onzks.com) **Problem**: User doesn't have a ZKScore identity\ **Solution**: Prompt user to create an identity using `sdk.identity.mint()` **Problem**: Too many API requests\ **Solution**: Implement exponential backoff and caching **Problem**: Scores appear outdated\ **Solution**: Scores update in real-time, check for caching issues ### Debug Mode Enable debug logging to troubleshoot issues: ```typescript theme={null} const sdk = new ZKScoreSDK({ apiKey: 'your-key', debug: true, // Enable debug logging }); // Debug logs will show: // - API requests and responses // - Cache hits and misses // - Error details // - Performance metrics ``` ## Community Resources Get help from developers Code examples and templates Latest updates and tutorials Step-by-step video guides ## Migration Guides ### From v1 to v2 Install the latest SDK version ```bash theme={null} npm install @zkscore/sdk@latest ``` Replace deprecated methods with new ones ```typescript theme={null} // Old const client = new ZKScoreClient(apiKey); const score = await client.getScore(address); // New const sdk = new ZKScoreSDK({ apiKey }); const score = await sdk.scores.getScore(address); ``` Verify all features work correctly ## Support Complete API and SDK documentation Real-time community support Report bugs and request features Direct support for enterprise users *** **New to ZKScore?** Start with our [Getting Started Guide](/guides/getting-started) for a quick 5-minute setup.
