How Arc Terminal Gave Its AI Agents Multichain Data With Zerion API

Arc Terminal is building a decentralized AI operating system. It combines DeFi tools with privacy-preserving AI agents. The team needed multichain wallet data for portfolio analytics. But they didn't want to waste time on stitching chain-by-chain data sources. The product had to work across every major network from day one.

That's where Zerion API came in.

What is Arc Terminal?

Arc Terminal is a modular, onchain operating system built by Ka Labs. 

Arc brings together three core pillars: 

• AI agents powered by an emotional intelligence SDK for personalized conversations, 
• a full financial suite with portfolio analysis and multi-wallet tracking, 
• a creative suite for image and meme generation.

All user data flows to decentralized storage, so users retain ownership of their data and AI interaction history. The platform supports login via X or Google and offers a credit-based system for using AI agents or running portfolio analysis.

Arc Terminal has grown quickly. It now has over 30,000 active users, processing more than 80 million API calls during its beta period.

The challenge: Multichain wallet data for AI-powered finance

Arc Terminal's financial suite is built around giving users detailed, cross-chain portfolio visibility.

Users connect wallets across Solana, Ethereum, Base, and other EVM chains. Then the platform's quantitative models analyze holdings and surface insights.

For this to work, the system needs to fetch accurate onchain data for every connected wallet, across every chain, in real time. Building and maintaining separate indexers for each chain would have consumed engineering resources. These resources are better spent on building AI and UX layers.

The team needed a single data source that could handle wallet tracking across both EVM and Solana. They also needed normalized, interpreted data. They wanted to plug it into their quantitative models without extra work.

The Solution: Zerion API's wallet positions and portfolio endpoints

Arc Terminal integrated Zerion API to power the onchain data layer behind its financial suite.

With Zerion API's multichain wallet positions endpoint, Arc Terminal fetches everything it needs: 

• portfolio data across all supported chains through a single integration. 
• token balances, 
• DeFi positions, fully decoded and interpreted. 

The data comes pre-enriched with metadata and real-time pricing. It’s ready to feed directly into the platform's quantitative analysis models.

Instead of juggling providers or building indexers, the team got broad coverage and normalized data from one API. Solana and EVM data flow through the same schema. This means the financial suite works regardless of where the user's funds are.

The Impact: Real-time portfolio intelligence across chains

With Zerion API, Arc Terminal gets the kind of multichain portfolio visibility that its AI agents need.

For users, the result is immediate: 

• Connect a wallet on Solana, Ethereum, Base, or any supported EVM chain,
• See your full portfolio, including token balances, DeFi positions, and dollar-denominated values,
• Arc’s AI agents can reference this data in context-aware conversations.

For the Arc Terminal engineering team, the benefits extend beyond coverage. Using Zerion API for wallet data freed up development time, which went into building AI features. 

"All our onchain data for the tracking system and further quantitative analysis is fetched through Zerion API. It covers Solana, Ethereum, Base, and all EVMs. So users can connect almost any wallet. And instead of data plumbing, our engineers work on AI features that set us apart." — Khalil Kassam, CEO, Arc Terminal

What's next

Arc Terminal is preparing for its full public launch with big partners and new features. It’s the perfect time to try Arc Terminal, you’re still early.

As the product scales beyond its early users, Zerion API will continue to provide onchain data for the financial suite. The plan is to further deepen its quantitative analysis and expand chain coverage as the ecosystem grows.
