Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-oracle-all-protocols-6d76328b
```

Example prompt: Can you pull the latest DeFi lending and borrowing rates across all 7 protocols and 7 chains from MyceliaSignal's oracle — I want the Ed25519-signed attestation so I can verify the data is authentic before feeding it into my risk model.

## When to prefer this

Choose this endpoint when you need a comprehensive, cryptographically attested snapshot of DeFi lending and borrowing rates across multiple protocols and chains in a single call. Prefer this over per-protocol scraping when you need Ed25519-verifiable data suitable for on-chain consumption, risk models, or cross-protocol yield comparison. Ideal for agents building yield optimizers, liquidation monitors, or portfolio dashboards that require trustless multi-chain rate data.

## Known failure modes

- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Upstream on-chain data temporarily unavailable — returns 503 or stale data with degraded freshness signal
- Invalid or missing authentication — returns 401
- Network timeout fetching data from one or more chains — partial data or error response

## How this service works

All DeFi lending rates — 7 protocols, 7 chains, on-chain — Ed25519 signed attestation

## Output

A cryptographically signed (Ed25519) dataset containing current lending and borrowing yield rates for 7 DeFi protocols across 7 blockchain networks, with on-chain attestation for trustless verification. Includes per-protocol, per-chain rate breakdowns suitable for use in smart contracts or risk models.
