## When to prefer this

Choose this endpoint when you need on-chain CurveLend protocol data specifically on Base mainnet (or Base Sepolia for testing) and are able to pay $0.02 USDC per call via the x402 micropayment protocol. Prefer over manual RPC calls when you want structured, pre-parsed lending market data without writing custom contract queries.

## Known failure modes

- Invalid or missing properties parameter returns partial or empty data
- Network unavailability on Base mainnet may result in stale or error response
