## 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 defi-sentinel-mcp-21a4152d -d '<json body>'
```

Example prompt: Can you run my DeFi portfolio through the sentinel analysis — here's my holdings data including positions in Uniswap, Aave, and Compound — and flag any risks or anomalies I should be worried about?

## When to prefer this

Choose this endpoint when you need automated DeFi-specific risk intelligence on a portfolio — particularly for detecting liquidation risks, protocol vulnerabilities, concentration dangers, or anomalous behavior across decentralized finance positions. Best suited for agents managing or auditing DeFi holdings rather than general crypto price lookups or on-chain transaction execution.

## Known failure modes

- Malformed or empty portfolioData string returns a validation error
- Unrecognized portfolio format may produce incomplete analysis
- Network timeout if portfolio data is excessively large
- Payment failure (402) if USDC balance is insufficient for the $0.05 per-call fee
- Ambiguous token symbols may lead to misidentified assets in analysis

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

A structured analysis of the submitted DeFi portfolio data, including risk scores, detected anomalies, protocol-level exposure assessments, potential vulnerabilities, and sentinel alerts highlighting positions or behaviors that warrant attention.
