## 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 signalpulse-thematic-basket-signal-3c38a989
```

Example prompt: Give me the basket signal for the AI theme — I want to know if it's a LONG, SHORT, or WAIT call right now, plus which stocks are leading and which are lagging.

## When to prefer this

Choose this endpoint when you need a basket-level directional read on a named investment theme (AI, semis, defense) or a sector ETF (XLK, XLE), rather than a single-stock signal. It is particularly valuable for identifying leadership rotation, intra-basket spread trades between leaders and laggards, and gauging whether sector breadth supports a directional trade. Prefer it over individual stock endpoints when your decision depends on aggregate sector momentum rather than a single name.

## Known failure modes

- Invalid or unrecognized theme id returns an error (e.g. unknown theme slug)
- Invalid ETF ticker returns a not-found or unsupported ticker error
- Service unavailable or timeout if market data feed is delayed
- Payment failure or insufficient USDC balance blocks the call
- Empty constituent list if the basket has no tracked members

## How this service works

SignalPulse thematic-basket signal — pass a theme id (ai, semis, defense, …) or a sector ETF ticker (XLK, XLE, …) and get a basket-level directional read: breadth (percent of constituents trending up), dispersion, and leadership rotation, with a LONG/SHORT/WAIT call on the basket or the intra-basket leaders-vs-laggards spread, plus named leaders and laggards.

## Output

Returns a structured basket-level signal including: a directional call (LONG, SHORT, or WAIT) on the basket or the leaders-vs-laggards intra-basket spread, breadth (percentage of constituents trending up), dispersion metric, leadership rotation indicator, and named lists of current leaders and laggards within the basket.
