## 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 deltasignal-covenant-stress-natural-language-brief-cdb56bb9
```

Example prompt: Pull me a DeltaSignal covenant stress brief for RIOT — give me the natural language summary of their covenant risk and diligence signals.

## When to prefer this

Use this endpoint when you need a fast, natural-language covenant stress and diligence triage signal for a crypto-adjacent public company (e.g. Bitcoin treasury holders, crypto miners). Prefer this over raw financial data APIs when you want pre-synthesized risk language ready for agent consumption, and over generic equity APIs when the focus is on covenant health and crypto-company-specific treasury-strength signals.

## Known failure modes

- Missing or invalid ticker symbol returns a 400 or empty payload
- Unsupported ticker (not a recognized crypto public company) may return minimal or null brief
- Payment failure via x402 results in 402 response blocking data access
- Period parameter not supported for all tickers, may be silently ignored
- Upstream data unavailability may result in incomplete or stale brief
