Docs / Aave v3 risk card

How do I read Aave v3 risk for an address before my agent acts?

Meridian by MioDio gives back an Aave v3 snapshot for one EVM address on Base or Ethereum: health factor, collateral, debt, available borrows, LTV, and liquidation distance, for $0.005 USDC on Base via x402. Upstream RPC failure is a charged 200 with status partial.

Fields returned

Demo card includes aave_v3 with protocol, pool, total_collateral_usd, total_debt_usd, available_borrows_usd, liquidation_threshold_pct, ltv_pct, health_factor, and raw Pool.getUserAccountData fields. MVP uses that pool read only.
