## 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 xx402-base-defi-risk-data-api-e2ceb626
```

Example prompt: Give me a Base DeFi risk assessment for a $25,000 treasury budget with a max single position of $5,000 — show me the top 10 protocols, yield pools, and stablecoins ranked by safety.

## When to prefer this

Choose this endpoint when an AI agent or autonomous risk tool needs structured, actionable DeFi risk data specifically for the Base blockchain — including protocol rankings, yield pool analysis, stablecoin safety scores, and capital authorization guidance — especially when operating within defined budget and position-size constraints. Best suited for agents that need a single bundled risk packet rather than making multiple separate API calls to different DeFi data sources.

## Known failure modes

- Payment not received or x402 micropayment handshake fails — returns 402 Payment Required
- Invalid query parameters (limit out of 3-12 range, negative USD values) — returns 400 Bad Request
- Upstream data source unavailable — source_status may show degraded or failed feeds
- Rate limiting if called too rapidly within the repeat_purchase_window

## How this service works

Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.

## Output

Returns a JSON object containing: risk breakdown by protocol, ranked lists of top protocols/stablecoins/yield pools, risk and fee quality queues, incident history, capital authorization status, position move queue, defi decision recommendation, treasury action guidance, source status, and a not-financial-advice disclaimer.
