10 things you wished your Crypto Data API did....but most don't 🫠 1. Real-time Portfolio Updates No more “refresh and pray.” APIs should sync with wallets as fast as the chain moves with P99 3s latency 2. Multichain Coverage (Not Just EVM) You need complete user visibility across 25+ networks and solana 👀 3. Webhooks that Actually Trigger in Real-Time 10 things you wished your Crypto API did....but most don't 🫠 4. Real-time Portfolio Updates: No more “refresh and pray.” APIs should sync with wallets as fast as the chain moves with P99 3s latency 5. Rich Transaction Histories Decoded, enriched, and categorized. No raw hex dumps. 6. DeFi Positions You Can Actually Use Borrowed, staked, LP’d, lent - All unified in one API call. 7. PnL (Profit & Loss) tacking per token - because why should traders have all the math? 8. Human-Readable API Responses - devs deserve better 9. AI-Ready Data Pipelines If your AI agent can’t understand the wallet…let alone it can understand the user 10. Reliable. Always. Because infra isn’t “nice-to-have.” U It’s the backbone of your UX - Don't compromise without a 99.99% uptime Want to know the API for onchain data that actually gets all 10 of these points ticked off? comment 'API' under this post

Zerion API 🤝 Fintech

Your AI Agent Is Only as Smart as the Wallet Data Behind It This is what Heurist AI's founder Jiewen Wang had to say: “Zerion's multi-chain wallet API gives our AI agents the ability to understand users' complete portfolios across all major networks. This visibility enables personalized experiences for blockchain users.” HeyElsa AI uses Zerion to return a user’s full portfolio in seconds - whether the prompt is typed or spoken. Speed and completeness change how helpful an AI feels. And then there’s Kirha, whose platform empowers onchain agents with deeper analytics. By integrating Zerion API, they gain scalable access to: > Wallet balances and history across 25+ blockchains > 8,000+ DeFi protocols and niche LPs > Real-time response speeds that can keep up with AI workloads > Composable endpoints that blend seamlessly into their stack We didn’t set out to build an API for AI agents. But it turns out: understanding wallets is the fastest way to train smarter ones. If you’re building AI that thinks like a trader or investor, it needs to see like one too.

What’s the hardest part about building wallet infrastructure in 2025? If you're working on anything involving: - Real-time portfolio data - Multichain asset tracking - Wallets, AI agents or consumer social apps We'd love to hear what blockers you're facing. We're building the infra behind apps like Uniswap Wallet, Rainbow, Warpcast, and Infinex — and constantly learning from the devs we support. Drop your thoughts below 👇  

You Don’t Need to Reinvent Wallets. Just use Better APIs By integrating Zerion’s real-time transaction and portfolio APIs early on, Privy significantly streamlined its backend and delivered a smoother user experience with minimal engineering overhead. This was a key enabler of their fast go-to-market. “Since day one, their reliable data has given our engineers the speed and reliability to deliver real-time crypto UX.” — Max Segall, COO Privy used Zerion for:  🔌 Easy-to-integrate REST APIs that just worked  📦 Unified access to both portfolio and transaction data  📉 2–3x cheaper PnL and token analytics compared to other providers Privy, later acquired by Stripe, kept their wallet experience fast and reliable from day one. If you're building embedded wallets, swaps, or anything onchain, Zerion can help you do the same! Test our API (free for solo devs) https://xmrrwallet.com/cmx.plnkd.in/gMay_pZY

If you're building in Crypto, you’ve probably hit one of these walls: > You’re juggling RPCs from 5+ chains > Spending hours trying to calculate one user’s actual PnL > Wondering if your infra will scale once real users show up? That’s exactly why we built the Zerion API - for ourselves first. It’s the same infrastructure that powers our wallet and many other leading products in the space (used by 450K+ people), now available for any developer building in crypto. What you get: ✅ Real-time portfolio data ✅ Structured positions and transaction history ✅ Spam filtering via Blockaid ✅ Multichain by default (16+ supported) ✅ Scalable WebSocket-ready infra ✅ Easy onboarding (free tiers for devs) Get your free API key here: https://xmrrwallet.com/cmx.plnkd.in/gMay_pZY
