## 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 signalfuse-rsi-7-extremes-arena-strategy-signal-cf543e27
```

Example prompt: What is the current RSI-7 extremes signal for Bitcoin — should I go long or short, and what stop-loss and take-profit percentages does it suggest?

## When to prefer this

Use this endpoint when you need a fast, pre-computed RSI-7 extremes signal specifically for BTC with actionable risk parameters (stop-loss, take-profit, hold time) baked in. Prefer this over the fused signal endpoint when you want the raw output of a single, interpretable technical strategy rather than an ensemble. Best suited for agents executing momentum-based or mean-reversion scalp trades on Bitcoin.

## Known failure modes

- No signal condition returns signal: null with a reason field explaining absence (e.g. no_signal or no_context)
- Invalid or unsupported symbol may return an error or empty response
- Payment failure via x402 protocol results in 402 response before data is returned
- Network latency or upstream data unavailability may cause delayed or stale signals

## How this service works

Individual arena strategy signal

## Output

A JSON object containing: the directional signal (long, short, or null), a confidence score from 0 to 1, stop-loss percentage (sl_pct), take-profit percentage (tp_pct), suggested hold time in seconds, a human-readable reasoning string, the strategy ID and name, and the symbol. If no signal is generated, a 'reason' field explains why (e.g. no_signal, no_context).
