## 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 silverback-x402-onrender-com-8d8286b5
```

Example prompt: Can you run a 14-day technical analysis on Ethereum — I want to see the RSI, MACD, and Bollinger Bands to know if it's a good entry point right now.

## When to prefer this

Use this endpoint when you need classic momentum and trend indicators (RSI, MACD, Bollinger Bands) for a crypto token available on CoinGecko. Prefer this over generic price endpoints when you need to assess overbought/oversold conditions, momentum shifts, or volatility bands. Best suited for short-to-medium term analysis windows of 1 to 30 days.

## Known failure modes

- Invalid CoinGecko token ID returns an error or empty result
- Unsupported timeframe value (not 1, 7, 14, or 30) returns a validation error
- Token with insufficient price history may return incomplete indicators
- Service unavailable or slow response due to Render.com cold start
- Payment failure via x402 results in 402 response before analysis is returned
