## 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 httpay-xyz-b2108226 -d '<json body>'
```

Example prompt: Find me the best simulated yield opportunities for USDC on Base right now — show me the top options by APY with protocol names and risk levels.

## When to prefer this

Use this endpoint when an agent needs to surface yield-earning opportunities in DeFi, particularly on Base, and a simulated or aggregated view is acceptable. Prefer this over manual protocol queries when comparing multiple protocols at once for a given asset. Note that results are simulated, so avoid when real-time on-chain accuracy is critical.

## Known failure modes

- Invalid or unsupported asset type returns empty results or error
- Chain not supported returns 400 or empty set
- Simulated data disclaimer — results are not real-time and may not reflect actual on-chain yields
- Payment not processed (x402) returns 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Malformed POST body returns 400 Bad Request
