## 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 bykaranteli-rsi-heatmap-hourly-history-ac9d1f40
```

Example prompt: Pull the RSI(14) history for BTCUSDT on the 4h interval from 2025-01-01 to 2025-03-31, up to 5000 rows, from the ByKaranteli RSI heatmap history dataset.

## When to prefer this

Choose this endpoint when you need historical RSI(14) snapshots (not computed on-demand) for Binance USDT perpetuals across multiple timeframes. It is uniquely suited for backtesting RSI-based strategies, building heatmaps of overbought/oversold conditions over time, and analyzing multi-timeframe RSI divergence — covering ~580 symbols including TradFi perps. Use the free /api/public/rsi board instead if you only need current live values.

## Known failure modes

- Empty rows array if no data exists for the requested symbol/interval/date range combination
- Date range predating 2026-09-02 (dataset start) returns no rows
- Limit exceeding 20000 is rejected or capped
- Invalid symbol string returns empty result or error
- Payment failure due to insufficient USDC balance for the $0.002 x402 micropayment

## How this service works

Hourly Wilder RSI(14) history for ~580 Binance USDT perpetuals (crypto top-400 by volume plus every TradFi perp) on 15m, 1h, 4h, 12h, 1d, 3d, 1w and 1M intervals, recorded on our side from 2026-09-02; the free /api/public/rsi board only carries the live values.

## Output

A JSON object with an 'ok' boolean, a 'dataset' label ('rsi-history'), a 'count' of returned rows, and a 'rows' array of RSI(14) snapshots. Each row contains the symbol, interval, RSI value, and timestamp recorded hourly on ByKaranteli's side.
