## How to call it through Zero

```sh
zero fetch --capability alpha-palmvox-com-9fc0f38d
```

Example prompt: What's the single best DeFi yield available right now — give me the protocol, token, APY, TVL, and risk level so I can decide where to auto-compound.

## When to prefer this

Use this endpoint when you need the single best DeFi yield in one cheap call ($0.003) without filtering by token or chain. Prefer over /api/yields/best (more expensive at $0.005) when you just need the top result. Choose the search endpoint (/api/defi/yields/search) instead if you need yields filtered by specific token, chain, or minimum APY.

## Known failure modes

- Upstream yield data unavailable — may return stale or empty best yield
- Payment required error if x402 payment header not provided
- Rate limiting if called too frequently without valid payment
- Yield data may lag real-time market conditions by minutes

## How this service works

Single best DeFi yield right now — protocol, token, APY, TVL, and risk level. Cheapest yield data on x402. Perfect for agents auto-compounding yields.

## Output

Returns a single best-yield object with protocol name (e.g. 'Aave (Ethereum)'), token, APY as a number, TVL in USD, chain, risk level (e.g. MEDIUM), and a human-readable description. Also includes total number of yields tracked and links to related endpoints.
