## 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-signal-for-sol-a3e2a2f1
```

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

## When to prefer this

Choose this endpoint when you specifically want the RSI-7 Extremes strategy signal for SOL, as opposed to a fused multi-strategy signal. It is ideal for agents that want to compare individual strategy outputs, back-test specific strategy performance, or trade a single well-defined mean-reversion/momentum signal with explicit risk parameters (stop-loss, take-profit, hold time) baked in. Prefer the fused signal endpoint if you want a consensus view across multiple strategies.

## Known failure modes

- No signal generated — signal field is null with a 'reason' field explaining the absence (e.g. 'no_signal' when RSI is not at an extreme)
- Symbol not supported — may return an error if a non-supported ticker is used
- Stale or missing market data — could result in null signal with 'no_context' reason
- Rate limiting or payment failure — x402 payment of $0.001 USDC not processed correctly
- Network timeout — real-time data dependency may cause occasional latency spikes

## How this service works

Individual arena strategy signal

## Output

A JSON object containing: the signal direction ('long', 'short', or null), a confidence score between 0 and 1, stop-loss percentage (sl_pct), take-profit percentage (tp_pct), suggested hold time in seconds (hold_time_sec), a human-readable reasoning string, the strategy_id ('rsi_7_extremes'), strategy_name, and the symbol ('SOL'). If no signal is generated, a 'reason' field explains why (e.g. 'no_signal', 'no_context').
