## 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 api-aitrailblazer-net-2f5411ab
```

Example prompt: Pull the top 10 most financially stressed crypto public issuers from the current DeltaSignal slice — I want to see their risk tiers, stress scores, and whether their stress is rising or falling.

## When to prefer this

Use this endpoint when you need a quick leaderboard of the most financially stressed crypto public issuers from the live DeltaSignal snapshot. Prefer this over single-issuer endpoints when you want a comparative cross-issuer stress ranking without specifying individual tickers. Ideal for morning briefings, risk screening, or alerting workflows where you need the top N most at-risk issuers ranked by covenant stress.

## Known failure modes

- Invalid limit value (non-integer or out of range) returns 400 Bad Request
- No current DeltaSignal slice available returns empty data array or 503
- Payment not completed (x402 protocol) blocks response
- Stale data if DeltaSignal slice has not been refreshed recently
