Powering agentic apps: HeyElsa, Ask Gina, Loomlay & Kirha.ai
Real-time, enriched onchain data across 42 chains — portfolio, positions, transactions, and PnL — ready for your agents via MCP and x402 payments.
Real teams, real results
How ai agents teams ship faster on the Zerion API — the challenge each faced, and what they built with it.
AI crypto copilot that analyzes and executes onchain actions.
Challenge
Elsa is an AI-powered personal finance assistant that helps crypto users find opportunities, trade smarter, and maximize returns. The team needed an efficient way to retrieve a user wallet's token positions to offer clear, immediate financial insights.
Solution
Elsa integrated the Zerion API's positions endpoint to effortlessly access wallet balances, delivering accurate, real-time meaning of underlying positions without the burden of indexing and interpreting blockchain data.
No-code platform to build and launch Web3 AI agents.
Challenge
LoomLay needed precise, easy-to-integrate wallet positions data to give its no-code AI agents the ability to view onchain crypto holdings.
Solution
LoomLay used Zerion's positions endpoint for clear, accurate wallet information, giving new powers to the AI agents built on its platform.
AI onchain wallet assistant for market data, holdings analysis, and transactions.
Challenge
AskGina, an AI wallet companion, required precise wallet portfolio data to deliver immediate financial insights and personalized recommendations.
Solution
AskGina leveraged the Zerion API's wallet positions endpoint to give users real-time, accurate data and AI-driven insights — built quickly during a Farcon hackathon, yet at production-ready scale.
Gateway that connects AI agents to real-time premium data via MCP.
Challenge
Kirha.ai required a streamlined onchain wallet data API to offer to LLMs, through both its chat and its API.
Solution
Kirha.ai adopted the Zerion API to easily integrate accurate wallet balances and transactions, so users can access onchain data alongside other information through a single chat and Kirha's own API.
