The Cambrian API is now publicly available

By the time you finish reading this post, AI agents will have analyzed more financial data than you will in your entire life. While this may sound threatening, it's actually an opportunity, and it's largely why I started Cambrian. Agents with superhuman data analysis abilities have already reshaped many global industries. It’s inevitable that they’ll revolutionize finance too. Today, I’m proud to announce the launch of the Cambrian API: the world’s best source of real-time and historical financial data across onchain and offchain sources. It’s fast, comprehensive, and accurate financial intelligence, critical for people and agents making winning decisions in today’s evolving markets.

We're living through what I call the Great Convergence: the lines between AI, finance, and digital assets are blurring together. This phenomenon will redefine global finance as we know it forever. For both crypto-native and institutional finance professionals, the opportunity is enormous. AI lets everyday developers and traders evaluate opportunities and manage risk at speeds and with skill that used to be reserved for professionals on Wall Street. Call it the democratization of finance: access to tools that were once available only to a select few.

At the same time, there's a massive wave of institutional adoption moving onchain. It started with stablecoins and is now expanding to RWAs, lending, onchain yield, perps, and prediction markets. When Franklin Templeton, a 75+ year old firm managing over $1.7 trillion, stands up a dedicated crypto unit, it becomes abundantly clear in which direction the industry is steering towards.

Anyone participating in the agentic finance revolution needs financial data that’s simultaneously fast, comprehensive, and accurate. For the first time ever, Cambrian solves agentic finance’s biggest problem.

Let’s say you want to use AI to work with RWAs, lending, yield, perps, and prediction markets. To do any of it well, you need financial intelligence. That's where individuals and institutions face the biggest friction, because existing financial data sources are simply inadequate for financial decision-making. That changes with the Cambrian API: today is the first day your agents can access premium onchain and offchain data that’s genuinely actionable.

To expand on the problem we’ve solved: human and agentic decision-making requires data that is fast, comprehensive, and accurate, but previous approaches have failed to deliver all three simultaneously. This is known as the Data Trilemma.

It matters more for agents than most people realize. Ask an LLM what ticker to buy, and you'll tend to get the same answer everyone else gets. That’s because models anchor on the most easily accessible data in front of them and, without richer context, they end up following the crowd. After all, LLMs tend to cluster around the average, rather than producing clever outlier results. That means agents can't just scrape the internet and expect an edge derived from slop. The difference between generating genuine alpha and becoming someone else's exit liquidity is the quality of the data feeding the model.

I built Cambrian to solve the Data Trilemma, and today I'm proud to make our first product publicly available: a single, unified API that gives agents and institutions the financial intelligence to make winning onchain decisions. It’s a single source of truth for tracking onchain financial activity, opportunities, and risk, replacing the fragmented data pipelines most teams stitch together today.

We’ve deliberately chosen depth over breadth. Most data solutions today spread themselves thin, offering shallow data across every chain, often aggregated from a multitude of third-party sources. We did the opposite. Our proprietary indexing stack derives intelligence directly from smart contracts, rather than repackaging what protocols self-publish through their own APIs. Our financial intelligence allows you to build strategies never before possible through an API, by virtue of being built upon data that no one else has.

Cambrian enables entirely new use cases across onchain finance. I’ll list some examples of how you can use our data below, but there are countless new possibilities for builders using our data.

Discover the best yield

Try the Base lending endpoint in our docs.

Cambrian helps you put your assets to work where they can earn the most. Where aggregators like DefiLlama stop at headline APY and TVL, we go a layer deeper: utilization, net-of-fee rates, and curator-level allocation showing how capital is actually deployed, all computed straight from each protocol's contracts. We have the deepest lending-protocol coverage on the market: APYs, utilization, supply and borrow caps, and vault and curator activity across lending protocols like AAVE, Euler, and Morpho, computed directly from each protocol's contracts. Curator-level analytics show how curators actually deploy capital, so you can run yield agents, compare real rates across protocols, and see where funds are moving. It's granular enough to reason about cross-collateralization, looping, and the risk that comes with them.

Make smarter trades

Try the Aerodrome V2 Pool Volume endpoint in our docs.

Cambrian helps you make smarter trades by providing a more granular view of underlying market activity. It’s all thanks to the best real-time and historical data available on Solana and Base (and more chains in the coming weeks), including holder distribution and wallet balance history to see who's accumulating, directional pool flow to understand market shifts, and with real-time and historical prices, including OHLCV, underneath it all.

Stay ahead of emerging trends

Try the Token Analysis endpoint in our docs.

Cambrian helps you tap into offchain data for smarter trend analysis. Deep42 is our agentic offchain intelligence engine, exposed through its own set of endpoints. It pairs onchain data with social sentiment, alpha from conversations on X, and accuracy rates for the industry's most-followed voices. Sentiment has always been a signal in finance. Deep42 makes it something your agent can actually query.

In 2023, some of the Cambrian founding team were working together at another company. Like the rest of the tech world, we were surprised by GPT-3.5’s capabilities, so we started experimenting with LLMs and onchain data. That year we built the industry’s first agentic copilot that answered natural-language questions about blockchain data, and we demonstrated the first LLM-driven DEX swap. During that time, we tried the existing blockchain data products, but none of them were optimal for agentic use.

By 2024, I had the conviction that 1) AI progress would continue to accelerate, 2) agentic finance would be the future, and 3) financial agents would require fast, comprehensive, and accurate data delivered over a simple API. This has been our vision from day one. We're not pivoting into this position like other data providers on the market today. We designed Cambrian to meet AI systems where they are today.

It’s easy for agents to tap into Cambrian data. Our MCP server is the fastest way for web-based agent harnesses like ChatGPT or Claude to get started. Our CLI brings the same data straight into terminal-based agent environments like Claude Code, Codex, Hermes, and OpenClaw, across all 80+ endpoints. And if pay-per-request is your preferred route, you can access the API via x402.

We cover Base and Solana today as they have captured the vast majority of agentic activity, with Ethereum Mainnet, Hyperliquid, and more chains coming soon.

AI agents get more powerful every month, and more financial activity moves onchain every day. Financial decisions are only as good as the data behind them, and Cambrian gives you the best data available.

Get started in under a minute: sign up with your email, get an API key, and point your agent at our docs. No credit card required. Start on the free tier and scale up to the Max or Enterprise plan as your needs grow.
