The v1 API gives you access to DeFi yield market data, user position tracking, transaction payload generation, and wallet-contextual insights across leading protocols such as Aave, Morpho, Euler, Compound, and Maker/Sky.
These are legacy v1 endpoints. They are fully supported and maintained — existing integrations can continue building on v1 with confidence. For new integrations, we recommend using the v2 endpoints, which offer an improved developer experience and all the data available in v1, plus more.

​
Endpoint categories

The v1 API is organized into four categories:

​
Market Data

Query real-time and historical TVL and APY data across lending and staking vaults. Retrieve data for a single vault, paginate across the full vault catalog, or pull benchmark rates for stablecoins and ETH. Explore Market Data endpoints →

​
Position Tracking

Look up a wallet’s active vault positions, idle token balances, transaction history, and estimated total returns for any vault they have interacted with. Explore Position Tracking endpoints →

​
Generate Payloads

Prepare calldata for supply, withdraw, request-redeem, claim-redeem, and claim-rewards interactions across supported protocols. The API is entirely non-custodial — it prepares transaction payloads without ever holding or controlling user funds. Explore Generate Payloads endpoints →

​
Contextual Insights

Surface the best yield opportunities for a specific wallet address, filtered by the assets it already holds, preferred networks, minimum TVL, and more. Powers integrations such as the Etherscan Yield Opportunity card. Explore Contextual Insights endpoints →
v2 endpoints are available at /api/general. v2 includes all v1 functionality plus additional data and a cleaner interface. We encourage you to check it out when starting a new integration.
