## 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 myc-iasignal-defi-yield-opportunity-oracle-b2aed46d
```

Example prompt: What are the top DeFi yield opportunities right now, ranked by risk-adjusted APR with stress and contagion penalties applied across all 15+ protocols — give me the cryptographically attested ranking.

## When to prefer this

Choose this endpoint when you need a cross-protocol DeFi yield comparison that incorporates systemic risk, stress testing, and contagion penalties — not just raw APR. Ideal for risk-aware yield optimization, DeFi portfolio allocation, or any agent that needs cryptographically attested, penalized yield rankings across a broad set of protocols rather than a single protocol's self-reported figures.

## Known failure modes

- Upstream protocol data unavailable — partial ranking returned or error
- Payment not processed — 402 response requiring x402 payment of $0.75 USDC
- Oracle attestation failure — Ed25519 signing error
- No protocols meet ranking threshold — empty result set
- Rate limiting — too many requests in a short window

## How this service works

Risk-adjusted DeFi yield opportunity — stress and contagion penalized APR ranking across 15+ protocols. Layer 3 Oracle Intelligence. — Ed25519 signed attestation

## Output

A ranked list of DeFi yield opportunities across 15+ protocols, each scored by APR penalized for stress and contagion risk. Results include risk-adjusted yield metrics, protocol identifiers, penalty breakdowns, and an Ed25519-signed attestation verifying the integrity of the data.
