## How to call it through Zero

```sh
zero fetch --capability onchainpulse-yield-intelligence-api-baa51376
```

Example prompt: Give me a risk-adjusted yield comparison right now across T-bills, stablecoins like USDC, and money market funds so I can see where cash is earning the most with the least risk.

## When to prefer this

Use this endpoint when an agent or user needs a cross-asset yield comparison that spans both onchain (stablecoin) and traditional (T-bill, money market fund) instruments in a single call with risk adjustment already applied. Prefer over raw DeFi data feeds when the goal is normalized, actionable yield intelligence rather than raw protocol data.

## Known failure modes

- Payment not received or invalid — 402 Payment Required returned
- Yield data temporarily unavailable due to upstream data feed issues — may return partial or stale data
- Invalid query parameters result in 400 Bad Request
- Rate limiting or service unavailability returns 503

## How this service works

Legislative intelligence, RWA market tracking, institutional monitoring, and onboarding guidance for the shift from traditional to onchain finance. x402 micropayment API.

## Output

A structured comparison of current yields across T-bills, stablecoin instruments, and money market funds, normalized for risk, enabling side-by-side evaluation of onchain and traditional cash-equivalent returns.
