Understanding DeFi APIs: A Practical Comparison Guide

**Zerion has integrated MegaETH support from launch day**, providing comprehensive tools for both users and developers. **Key features available:** - Trading, swapping, and bridging via Relay Protocol - Unified DeFi position tracking across platforms - Direct access to top MegaETH dApps - Portfolio monitoring capabilities This integration follows Zerion's active start to 2026, which included rolling out Feed for mobile users, TRON network support on iOS, Touch ID for the extension, and launching the Zerion API Dashboard. The API now powers multiple platforms including Sprinter, Pigeon, Corners, and Arc Terminal. Zerion continues its pattern of providing day-one support for emerging ecosystems, having previously done the same for Tempos testnet.

Zerion has released their January product updates for both their API and Wallet products. The announcement comes as part of their monthly highlights series, where they share new features and improvements added to their platform. **Key Points:** - Updates cover both Zerion API and Wallet - Released in early February covering January additions - Part of regular monthly update cadence Zerion continues to iterate on their multi-chain wallet and API infrastructure for web3 users and developers.

**Major AI agents now integrate Zerion API for blockchain data** Three leading crypto AI agents have adopted Zerion's infrastructure: - **@askginadotai** - interprets onchain activity through natural language - **@pigeon_trade** - executes transactions based on user intent - **@HeyElsaAI** - answers portfolio questions with real-time data All three use the same API endpoints originally designed for consumer interfaces. The integration provides AI agents with interpreted blockchain data rather than raw data, which reduces token usage and improves response times. **Key capabilities include:** - Token balances across EVM and Solana with prices - Labeled transaction history - DeFi positions for 8,000+ protocols - PnL tracking for addresses and tokens The adoption demonstrates that developer-friendly infrastructure works equally well for AI systems.

Two blockchain data providers are carving out distinct niches in the infrastructure space. **Zerion API** focuses on consumer-facing crypto applications, providing wallet data services for ambitious products including those building on Monad. The API enables developers to integrate comprehensive wallet functionality across multiple chains. **Allium** takes a different approach, specializing in compliant historical blockchain data. This positions them for enterprise and institutional clients requiring auditable, regulation-friendly data access. The divergence highlights how blockchain infrastructure is maturing into specialized services rather than one-size-fits-all solutions.
