## 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 sitecheck-crypto-technical-indicators-081db067
```

Example prompt: What are the current technical indicators for BTC-USD on the 1-hour chart — give me RSI, MACD, Bollinger Bands, and moving averages using the last 300 candles?

## When to prefer this

Choose this endpoint when you need pre-computed, multi-indicator technical analysis (RSI, MACD, Bollinger, ATR, SMA, EMA) for a Coinbase trading pair in a single call, rather than fetching raw candles and computing indicators yourself. Ideal for agents that need a quick technical read without building their own TA library. Best for Coinbase-listed pairs; not suitable for stocks, forex, or pairs not listed on Coinbase Exchange.

## Known failure modes

- Missing required 'pair' query parameter returns an error
- Invalid pair format (not a Coinbase pair like BTC-USD) may return an error or empty data
- Granularity outside allowed values (1m, 5m, 15m, 1h, 6h, 1d) is rejected
- Limit outside 60-300 range is rejected
- EMA/SMA period count exceeding 5 or values outside 2-200 are rejected
- Coinbase Exchange API downtime may cause upstream data failure
- Payment failure (x402) results in no response

## How this service works

Technical indicators for one crypto pair and interval, computed from the last 60 to 300 candles: SMA and EMA for the periods you give (default SMA 20, 50, 200; EMA 12, 26), RSI 14 (Wilder), MACD 12/26/9, Bollinger 20/2, ATR 14, the latest values, and a plain trend note (above or below the 200 average, overbought or oversold). Candles come from Coinbase; the newest candle may still be forming. Information only, not financial advice.

## Output

Returns a JSON object with the current price, RSI-14, MACD (line, signal, histogram), SMA values (configurable periods, default 20/50/200), EMA values (configurable periods, default 12/26), Bollinger Bands (upper, lower, middle, %B), ATR-14, a trend summary (RSI sentiment + position vs 200-period SMA), candle count used, granularity, timestamp, data source attribution, and a disclaimer.
