## 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 cabrini-full-research-brief-5c1ca14b -d '<json body>'
```

Example prompt: Pull a full research brief for NVDA as of today using the last 60 days of price history — I want price action, fundamentals, insider transactions, and splits all in one shot.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-dimensional view of a single US stock in one call — replacing the need to individually query price history, fundamentals, insider transactions, and split data. It is the most cost-efficient and latency-efficient option for full stock due diligence tasks where multiple data dimensions are required simultaneously. Prefer it over individual Cabrini endpoints when you need 3 or more data types for the same ticker at the same time.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error
- Future as-of date or dates with no trading data may return empty or error
- lookback_days outside supported range may be clamped or return an error
- Payment failure or insufficient USDC balance blocks the call
- Rate limiting if too many requests are sent in quick succession
