## 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 signalbrew-summary-aggregated-technical-analysis-rating-4599e40f
```

Example prompt: What's the overall technical analysis rating for BTC/USDT on Binance using 1-hour candles — how many indicators are voting buy vs sell right now?

## When to prefer this

Choose this endpoint when you need a single aggregated technical analysis verdict (buy/sell/neutral) across many indicators at once, rather than querying individual indicators separately. It is ideal for trading bots, AI agents, or dashboards that need a quick consensus signal without managing API keys or subscriptions — pay-per-call via USDC makes it suitable for low-frequency or on-demand use. Prefer it over building your own indicator aggregation when you want a pre-computed, scored summary with named indicator breakdown in one call.

## Known failure modes

- Unsupported exchange name returns an error or empty result
- Unknown or delisted trading symbol returns no data
- Invalid interval value (e.g. unsupported timeframe) returns an error
- Payment not sent or insufficient USDC results in HTTP 402 rejection before processing
- Rate limiting or infrastructure issues may cause transient 5xx errors
- Stale market data if the exchange feed is lagging may produce outdated indicator values
