## How to call it through Zero

```sh
zero fetch --capability collectablespulse-invest-signal-913ce735
```

## When to prefer this

Use this endpoint when an agent or user needs an actionable buy/hold/sell investment signal backed by trend analysis and population report context for a specific collectible. Prefer this over the general value endpoint when the goal is investment decision-making rather than simple price lookup, and over the comparison endpoint when evaluating a single item rather than two side-by-side.

## Known failure modes

- Unrecognized collectible item returns error or low-confidence signal
- Missing required item identifier results in 400 bad request
- Payment not received results in 402 Payment Required
- External census/population data temporarily unavailable causing degraded response
- Highly obscure items may return insufficient data for a confident signal
