## 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-stress-score-feed-4e521324
```

Example prompt: Pull the DeltaSignal stress feed for all CRITICAL risk-tier issuers, show up to 20 results starting from offset 0, and filter to only those with a minimum stress score of 2.5.

## When to prefer this

Use this endpoint when you need a ranked, filterable list of issuers by financial stress score and risk tier — especially for screening multiple securities at once. Prefer this over single-issuer endpoints when building a watchlist, running a portfolio stress screen, or identifying the most at-risk names across the full universe. Ideal for agentic workflows that need to iterate over stressed issuers paginated by offset.

## Known failure modes

- Invalid risk_tier enum value returns 400 or empty results
- min_stress out of expected numeric range may return empty data set
- Offset beyond row_count returns empty data array
- Payment not provided or insufficient USDC triggers 402 Payment Required
- Network or upstream data pipeline outage returns 500 or timeout

## How this service works

Compatibility alias for the DeltaSignal covenant stress screen.

## Output

Returns a paginated JSON array of issuer records, each containing the ticker symbol, mp_z stress score, risk_tier classification (CRITICAL/HIGH/MODERATE/LOW/UNCLASSIFIED), atlas_tier label (e.g. Tower), stress_50pct value, and debt_coverage_status string. The meta object includes limit, offset, total row_count, and source_date.
