Cambrian now supports Ethereum Mainnet

I’m proud to announce that the Cambrian API now supports Ethereum mainnet. Every agent, protocol, and institution can now query real-time and historical financial intelligence on Ethereum and build on actionable data like curator-level vault allocations, pool-level swap volume, and wallet-level holder distributions.

Ethereum is the number one chain for financial activity. It holds more TVL than any other network (the #2 chain doesn’t even come close), commands more institutional trust than any other network, and is home to the majority of onchain lending capital. When a fund, a protocol, or an agent decides where serious capital should live, the answer is usually Ethereum.

Until now, that capital moved on intelligence that was fragmented, slow, or just really shallow and devoid of context. That era is over. Financial intelligence has arrived on Ethereum.

Cambrian's proprietary indexing stack derives intelligence directly from onchain transactions and smart contracts, reading state and events at the source instead of repackaging what protocols self-publish through their own APIs. When the data comes straight from the contract transactions, you get numbers that reflect what's actually happening onchain rather than what someone chose to report. The result is true financial intelligence, including:

Query Aave V3, Morpho, and Euler markets with deep coverage that’ll help with your allocation decisions. Our lending intelligence includes utilization, net-of-fee rates, and curator-level vault allocations. Most aggregators stop at headline APY and TVL. If you’re deploying capital on Ethereum lending pools, you need to see what's underneath the advertised APY.

Cambrian’s DEX intelligence on Ethereum includes pool-level TVL, swap volume, fee APR, and volatility across DEXes like Uniswap, PancakeSwap, and SushiSwap. Whether you're routing a trade, managing LP positions, or monitoring liquidity migration, the data resolves to the pool level and updates in real time.

Query data like live and historical pricing, ERC-20 token listings, address-level holdings, and top-owner distributions. Data points like these are the raw material for treasury monitoring, risk dashboards, and market surveillance.

One request is all it takes to start working with Cambrian’s rich data. Here’s an example: let’s analyze the Uniswap V3 USDC/WETH 0.05% liquidity pool Ethereum:

curl "https://api.cambrian.org/evm/uniswap/v3/pool?chain_id=1&pool_address=0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640" \
-H "X-API-Key: $CAMBRIAN_API_KEY"

At the time of writing, here’s what that result looks like:

Grab a free API key at cambrian.org/pricing and make your first Ethereum query today. You’ve got options: via REST, or our MCP server for web-based agents, or the CLI for terminal environments, or x402 for pay-per-request access. You don’t even have to generate a key to get acquainted with the API, just paste this command to your agent now:

Cambrian is continuously ingesting more financial data, onchain and offchain, to produce the best financial intelligence across every chain we index, with more chains on the way.

Cambrian is the financial intelligence layer for agents and institutions. Our API delivers real-time and historical blockchain data, covering yield, liquidity positions, risk, trading activity, and market sentiment, for agentic and institutional DeFi applications. Founded in 2024, Cambrian is backed by Polychain Capital, Franklin Templeton, a16z crypto, Flow Traders, Selini Capital, and others.
