## 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 cambrian-x402-api-aave-v3-lending-pools-1c6e7c37
```

Example prompt: Pull all the current Aave v3 lending pools from Cambrian's blockchain data API so I can see which assets are available to borrow and supply, along with their rates.

## When to prefer this

Choose this endpoint when you need on-demand, pay-per-use Aave v3 lending pool data without managing your own indexer or RPC node. Ideal for autonomous agents that need current pool state for DeFi decision-making, rate comparison, or liquidity analysis on EVM chains. Prefer this over self-hosted solutions or heavier analytics APIs when low-cost, per-call access to structured Aave data is sufficient.

## Known failure modes

- Payment failure (402): USDC payment of $0.05 not completed or invalid — no data returned
- Invalid query parameters: unsupported filter fields may return empty array or error
- Chain not supported: querying for a non-EVM or unlisted chain returns no results
- Rate limiting or service downtime: provider-side availability issues
- Empty result set: no pools match the specified filters

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns an array of Aave v3 lending pool objects, each containing pool identifiers, supported asset details, current supply and borrow interest rates, total liquidity, and other pool-level metrics across EVM-compatible chains.
