## 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 signal-pathin-me-base-usdc-defi-yield-intelligence-report-4f128e2c
```

Example prompt: Pull the full Base USDC yield intelligence report for a $25,000 portfolio — I want ranked lending APYs across protocols like Aave, Moonwell, and Compound, the 30-day context, any protocol risk flags, and the preservation, balanced-growth, and yield-seeking allocation models with stress test results.

## When to prefer this

Use this endpoint when an agent needs a comprehensive, single-call DeFi yield intelligence snapshot for Base-chain USDC — including APY rankings, liquidity gates, risk flags, and portfolio-size-specific allocation models — rather than fetching raw on-chain data or querying individual protocol APIs separately. Ideal for agents advising on USDC capital deployment or rebalancing on Base.

## Known failure modes

- Missing or out-of-range capital_usdc (below 10 or above 1,000,000) returns a validation error
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- Upstream on-chain data temporarily unavailable may cause a 503 or stale-data response
- Invalid query parameter types return a 400 Bad Request

## How this service works

Base DeFi stablecoin yield intelligence for agents: ranked native-USDC lending and strategy APYs, liquidity and 30-day context, dated protocol risk flags, portfolio allocation models, and total-loss stress tests.

## Output

A structured report containing: ranked native-USDC lending and strategy APYs on Base, liquidity metrics and 30-day historical APY context, dated protocol risk flags for listed protocols, portfolio allocation models (preservation, balanced-growth, yield-seeking) scaled to the provided capital_usdc amount, and total-loss stress test scenarios.
