## 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 aave-defi-market-data-by-chain-vextorium-3e63f52e -d '<json body>'
```

Example prompt: What are the current supply and borrow APYs for all Aave v3 markets on Base, including how much liquidity is available and which assets I can actually borrow?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-asset snapshot of Aave lending markets on a specific chain — including both supply and borrow rates, incentives, utilization, and available liquidity — all in one call. Prefer it over manual DefiLlama scraping or chain-specific subgraph queries when you need aggregated totals alongside per-asset detail for Aave v2 or v3.

## Known failure modes

- Unsupported or misspelled network name returns empty or error response
- Invalid protocol version enum value causes request rejection
- DefiLlama data lag may cause stale rates during high-volatility periods
- Markets with zero liquidity may return null fields in the detail array
- POST body missing required fields returns schema validation error

## How this service works

## Output
