## When to prefer this

Use this endpoint when you need a quick, structured risk snapshot for a specific ERC-4626 vault on Base — especially share price, drawdown, APY, and withdrawable liquidity — without building your own on-chain data pipeline.

- Network congestion on Base may cause stale or delayed on-chain reads
- Payment of ~$0.04 USDC via x402 protocol not completed — request rejected
