## 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 signal-quickai-build-c96999c4
```

Example prompt: Run a full technical analysis on SOL using the 4-hour timeframe — I want all ten indicators and an overall bullish or bearish assessment.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-indicator crypto technical analysis snapshot in a single call rather than querying individual indicators separately. Ideal for trading assistants, crypto bots, or dashboards that need a professional TA summary with an actionable assessment for a specific token and timeframe.

## Known failure modes

- Missing required 'token' query parameter returns an error
- Invalid or unrecognized token symbol returns no data or error
- Invalid timeframe value (not one of 1m, 5m, 15m, 1h, 4h, 1d) returns validation error
- Payment failure or missing x402 payment header returns 402 Payment Required
- Network or upstream data provider unavailable returns 5xx error
