## 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-signal-api-sol-trend-endpoint-e7666af3
```

Example prompt: What's the current trend signal for SOL — is it in an uptrend or downtrend, how strong is it by ADX, and how far is the price from its 30-day support and resistance?

## When to prefer this

Use this endpoint when you need a concise, real-time technical trend snapshot for SOL specifically — including ADX-based strength scoring and regime duration — without needing to compute indicators yourself. Prefer this over generic price APIs when trend direction, support/resistance levels, and momentum classification are all needed in one call.

## Known failure modes

- Invalid or unsupported coin symbol returns an error
- Payment not processed (x402 payment required) results in 402 response
- Network timeout or upstream data feed unavailability causes 5xx error
- Stale data if market feed is delayed
