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 stratalize-stablecoin-yield-benchmark-44cadc7e
```

Example prompt: Pull the stablecoin yield benchmark for all assets — I need current supply APY across Aave, Compound, Morpho, and Spark with the spread versus the 3-month T-bill, and I want a cryptographically verifiable receipt.

## When to prefer this

Use this endpoint when a crypto treasury agent, portfolio manager, or DeFi analyst needs auditable, signed stablecoin lending rate benchmarks across multiple protocols and chains with a built-in comparison to risk-free T-bill rates. Prefer this over generic DeFi dashboards when cryptographic verifiability and spread-to-T-bill context are required for compliance or reporting.

## Known failure modes

- Invalid or unsupported asset enum value — returns 400 with validation error
- DeFiLlama or FRED data source temporarily unavailable — may return stale data or 503
- Payment not processed or insufficient USDC balance — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
