## 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-data-hub-best-yield-pools-79fe4c12 -d '<json body>'
```

Example prompt: What are the best yield pools on Base right now? Only show me stablecoin pools so I can avoid impermanent loss.

## When to prefer this

Choose this endpoint when you need a ranked, filtered view of current DeFi yield pools by chain and stablecoin preference. It is well-suited for agents helping users allocate capital into passive income strategies, compare yields across protocols, or avoid impermanent loss via stablecoin-only filtering. Prefer it over generic DeFi aggregators when you need a pay-per-query model without API key management.

## Known failure modes

- Payment not included or insufficient USDC — 402 response returned
- Invalid chain name string — may return empty results or validation error
- No pools found matching the given filters — empty array returned
- Service unavailable or Vercel cold start timeout — 503 or timeout error
