## 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 carbon-cashmere-eth-technical-indicators-api-7237a430
```

Example prompt: Pull the latest technical indicators for ETH — I want to see the RSI-14, MACD, Bollinger Bands, and the 20/50/200-bar SMAs so I can gauge whether it's overbought or showing a bullish crossover right now.

## When to prefer this

Use this endpoint when you need structured, pre-computed technical indicators for ETH specifically (RSI, MACD, SMA, Bollinger Bands) without having to calculate them yourself from raw OHLCV data. Prefer this over raw price feeds when your agent needs market signal context for trading decisions, portfolio alerts, or market commentary. The sibling 'trend analytics' endpoint (ADX) or 'mean-reversion analytics' endpoint may complement this for a fuller picture.

## Known failure modes

- Symbol not supported — endpoint is specifically for ETH; other symbols may return 404 or empty
- Cache miss may cause slightly higher latency on first request
- Stale data if upstream price feed is delayed — check timestamp in _meta
- Malformed response if API is under maintenance
- Payment failure via x402 protocol if USDC balance is insufficient
