# DeFi Lending Market Health & Solvency Intelligence (Base)

> DeFi Lending Market Health & Solvency Intelligence (Base) is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Returns per-market utilization, liquidity, TVL, total borrowed, debt ceiling, and a deterministic 0-100 health score with verdict for DeFi lending protocols on Base chain.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability defi-lending-market-health-solvency-intelligence-base-b41beaf2
```

Example prompt: What's the current health of the Aave v3 lending markets on Base for USDC — give me the utilization rate, available liquidity, and the health score verdict.

## When to prefer this

Use this endpoint when an AI agent needs a fast, pre-computed solvency and liquidity health assessment for Base DeFi lending markets without building custom DefiLlama pipelines. Ideal for risk checks before executing on-chain borrow/lend actions, monitoring protocol health, or surfacing liquidity warnings. Prefer over raw DefiLlama queries when a normalized health score and verdict are needed rather than raw data.

## Known failure modes

- Unsupported protocol slug returns 400 or empty results
- Chain value other than 'Base' is rejected by enum validation
- Unknown asset symbol returns empty market list
- DefiLlama data source unavailable causes stale or missing data
- Rate limit or payment failure returns 402

## How this service works

DeFi lending protocol-health + solvency intelligence for a protocol or asset on Base: per-market utilization, available liquidity, TVL, total borrowed, debt ceiling and a deterministic 0-100 health score plus verdict (healthy / tight-liquidity / elevated), protocol aggregates, and a rate/TVL trend — computed by us over DefiLlama data.

## Output

Returns a JSON object containing per-market stats (utilization rate, available liquidity, TVL, total borrowed, debt ceiling) plus a deterministic 0-100 health score with a verdict string (healthy / tight-liquidity / elevated), protocol-level aggregates, and a rate/TVL trend derived from DefiLlama data.
