## 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-3b4114b6
```

Example prompt: Pull the latest DeltaSignal covenant stress screen and show me all issuers at HIGH or CRITICAL risk tier with a minimum stress score of 0.7, up to 25 results.

## When to prefer this

Use this endpoint when you need a broad screened list of covenant-stressed crypto issuers across the entire DeltaSignal universe, with filtering by risk tier or minimum stress threshold. Prefer this over single-issuer endpoints when doing portfolio-level screening or building a watchlist. Use the single-issuer ATLAS covenant detail endpoint when you need deep per-issuer breakdown.

## Known failure modes

- No data available if the current DeltaSignal slice is stale or not yet generated
- Invalid risk_tier enum value returns a 400 validation error
- min_stress out of range (not a valid number) causes a 400 error
- Offset beyond the total result count returns an empty list
- 402 Payment Required if x402 payment header is missing or insufficient

## How this service works

Screen the latest DeltaSignal covenant stress slice.

## Output

A paginated list of crypto public issuers from the current DeltaSignal slice, each annotated with covenant stress scores, risk tier classification (CRITICAL/HIGH/MODERATE/LOW/UNCLASSIFIED), and optional linkbase-only filtering. Results reflect the latest available slice freshness.
