## 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-treasury-yield-risk-pulse-b90f930e
```

Example prompt: Pull the Base treasury yield risk pulse for a $10,000 risk budget, stable pools only, minimum TVL of $500,000, minimum APY of 2%, and a max single position of $2,500 — give me the top 6 candidates with risk breakdown and what to avoid.

## When to prefer this

Use this endpoint when an AI agent or risk tool needs a structured, actionable DeFi yield risk pulse specifically for the Base chain, particularly for treasury-style stablecoin allocation decisions. Prefer it over generic DeFi APIs when you need pre-filtered candidate pools, allocation caps, stop conditions, and a priority queue calibrated to a specific risk budget and position size limit.

## Known failure modes

- Invalid query parameter ranges (e.g. limit outside 3–12, APY outside -100–1000) return validation errors
- Upstream DeFi data sources unavailable may return degraded or partial source_status
- min_tvl_usd too high may return empty candidate pools
- Network or payment gateway issues may result in HTTP 402 or 5xx errors

## 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

A JSON object containing a pulse decision, buyer execution plan, treasury action, allocation cap, top candidate pools with risk scores, a priority queue, an avoid queue, a review queue, risk breakdown by category, stop conditions, recheck policy, source status, and a disclaimer — designed to guide an autonomous agent's next allocation action.
