Why Nacian?

Built for the next generation of DeFi applications and AI agents.

AI-Native Architecture

Most APIs are built for frontends. Nacian is built for agents. Our endpoints return strictly typed, context-optimized JSON that minimizes token usage while maximizing information density for LLMs.

Pay-Per-Call

Powered by x402. No monthly subscriptions. No wasted quotas. Stream micropayments only for the data you actually consume.

Unified Schema

One interface for all DEXs. We normalize data from Uniswap, Curve, and others into a single, consistent format.

Cross-Chain

Query liquidity and rates across Ethereum, Base, and Arbitrum without changing your integration logic.

Always Expanding

We don't stop at pools. Lending, derivatives, and yield farming data are coming, ensuring your agent stays ahead.
