## 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 signalbrew-rsi-indicator-binance-f07f5e81
```

Example prompt: What's the current 14-period RSI for AAVE/USDT on Binance using the 1-hour chart? I want to know if it's overbought or oversold right now.

## When to prefer this

Use this endpoint when you need a single, on-demand RSI calculation for a Binance-listed trading pair with live candle data, billed per-use at $0.005 USDC. Prefer this over self-hosted solutions when you want zero infrastructure overhead for crypto TA. Best suited for agents that need real-time momentum signals for trading decisions or alerts.

## Known failure modes

- Invalid or unsupported trading pair returns an error or empty result
- Unsupported interval/timeframe causes a 400 or 404 error
- x402 payment failure (insufficient USDC balance or misconfigured wallet) blocks the request
- Network or exchange sync lag may cause slightly stale candle data
- Invalid query parameter values (e.g. non-numeric length) return validation errors

## How this service works

Relative strength index (rsi) of any listed cryptocurrency pair, computed on demand from live-synced Binance, Coinbase, Bitget, KuCoin and OKX candles across fifteen intervals. Part of the SignalBrew pay-per-call technical analysis catalog: one flat USDC price per calculation over the x402 protocol, and invalid requests are never charged.

## Output

Returns a JSON object containing the computed RSI value as a decimal string, along with the trading pair symbol, exchange name, interval, the parameters used (e.g. length), and associated candle data used for the calculation.
