In a move that could fundamentally transform how crypto markets operate, Token Metrics has unveiled its highly anticipated AI-powered API and software development kit (SDK), providing the essential intelligence infrastructure that developers, traders, and institutions need to build their own high-performing trading AI agents.

The Intelligence Gap in Crypto Markets

For years, crypto market participants have faced a significant disadvantage against institutional players with proprietary AI systems. While most traders rely on lagging indicators and fragmented information sources, institutions leverage sophisticated algorithms and real-time analytics to capture alpha.

Token Metrics' CEO Ian Balina recognized this imbalance firsthand.

"What we've built is essentially the democratization of institutional trading advantages," Balina noted. "We're putting the same AI that spotted MATIC at $0.03 and SOL at $100 directly into an API that developers, traders, and funds can use to power their own trading agents."

Powering the Next Generation of Trading AI Agents

As trading agents and AI agents become mainstream in crypto, Token Metrics is positioning itself as the intelligence layer that fuels this trend. The API serves as the crucial foundation that enables users to build sophisticated AI trading agents without developing complex machine-learning models from scratch.

This API represents the culmination of web3 and AI technologies, helping brands and developers integrate advanced trading intelligence directly into their platforms, products, and services.

One API to Rule Them All: 20+ Intelligence Endpoints

The platform features over 20 specialized endpoints that developers can leverage to build various types of trading agents:
