## 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 cryptobuddy-96zq-onrender-com-7ad41475 -d '<json body>'
```

Example prompt: Give me a quick BUY, SELL, or HOLD signal for BTC along with how confident you are.

## When to prefer this

Choose this endpoint when you need only the minimal signal output — BUY/SELL/HOLD plus conviction — without any explanatory text or full metrics. It is faster and cheaper for high-frequency checks or when the agent only needs a binary/ternary decision rather than a full analysis. Use sibling endpoints if you need LLM explanation or detailed TOON metrics.

## Known failure modes

- Missing or invalid symbol returns a 400 or error response
- Unknown coin symbol may return an error or a low-conviction signal
- Payment failure via x402 protocol results in a 402 response blocking the request
- Service downtime on Render hosting may return a 503
- Rate limiting may reject rapid successive calls
