## 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-top-stressed-crypto-issuers-1ebc9fea
```

Example prompt: Pull the top 10 most stressed crypto issuers from DeltaSignal right now so I can see which ones are showing the highest covenant stress signals.

## When to prefer this

Use this endpoint when you need a quick, ranked screening of the most credit-stressed crypto issuers across the entire DeltaSignal universe, rather than drilling into a single issuer. Prefer this over single-issuer endpoints when you want a broad market view or need to triage which issuers deserve deeper analysis.

## Known failure modes

- Payment required (402) if x402 payment header is missing or invalid
- Empty result if no issuers are tracked in the current slice
- Stale data if the DeltaSignal slice has not been refreshed recently
- Invalid limit parameter may return an error or default behavior

## How this service works

Top stressed crypto issuers from the current DeltaSignal slice.

## Output

A ranked list of crypto issuers currently showing the highest covenant stress scores within the DeltaSignal tracked slice, including stress metrics and issuer identifiers, limited by the optional `limit` parameter.
