## 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 baron-power-play-alpha-defi-ai-signal-engine-558a4ecf
```

Example prompt: Give me the latest Baron Power Play AI trading signal — I want to know the primary market direction, which DeFi protocols to pick, confidence level, and what position size in USD to go with.

## When to prefer this

Choose this endpoint when an autonomous agent needs a self-contained, no-account, per-call DeFi AI trading signal settled on-chain via USDC — ideal for agent workflows that cannot hold API subscriptions or keys, need on-chain payment accountability, and require structured output with confidence and position sizing baked in.

## Known failure modes

- Payment not settled (402 if USDC payment on Base fails or is insufficient)
- Stale or low-confidence signal if market data inputs are unavailable
- No query parameters supported beyond basic GET, so no filtering by protocol or timeframe
- Service unavailable if Cloudflare Worker is down or rate-limited

## How this service works

Pay-per-call AI infrastructure for autonomous agents. USDC on Base, settled by Coinbase. No API key, no account, no subscription.

## Output

Returns a JSON object containing: a primary_signal field (e.g. BULLISH or BEARISH), an array of top_picks each with protocol name, signal direction, stop_loss_pct, and take_profit_pct, a confidence float between 0 and 1, and a position_sizing object with a recommended_position_usd value.
