## 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 x402-toolbox-defi-yield-pools-fc02b54e
```

Example prompt: Can you pull the current DeFi yield pool data so I can see which pools are offering the best APY rates right now?

## When to prefer this

Use this endpoint when an AI agent needs real-time or near-real-time DeFi yield pool data without setting up API keys or subscriptions — the x402 micropayment model ($0.003 USDC) makes it ideal for on-demand, pay-per-query yield data lookups within automated agent workflows operating on Base/USDC.

## Known failure modes

- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Invalid schema filter parameter — returns malformed or empty result
- Upstream DeFi data source unavailable — may return stale or empty pool list
- Rate limiting if called too rapidly in succession

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with ok and paid status flags, along with structured yield pool data including available DeFi pools, their APY rates, liquidity depths, protocol names, and token pair information.
