## 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-2bc79698
```

Example prompt: What does the current DeltaSignal risk-tier breakdown look like — how many crypto issuers are in each tier like LOW, MODERATE, HIGH, and CRITICAL, and what percentage do they represent?

## When to prefer this

Use this endpoint when you need a quick high-level snapshot of risk concentration across the entire active DeltaSignal issuer set, rather than drilling into a single issuer's details. Ideal for dashboard summaries, alerting on concentration risk, or understanding the macro stress posture before running deeper per-issuer queries.

## Known failure modes

- DeltaSignal slice not yet populated or stale — may return empty or zero counts
- Service unavailable (503) if ATLAS-7 data pipeline has not completed ingestion
- Payment not accepted (402) if x402 USDC payment header is missing or insufficient
- Unexpected schema change if slice metadata format has been updated

## How this service works

Risk-tier distribution for the active DeltaSignal slice.

## Output

A JSON object with four risk-tier keys (LOW, MODERATE, HIGH, CRITICAL), each containing a count of issuers in that tier and their percentage of the total active DeltaSignal slice. Example: LOW: 103 issuers (47.9%), HIGH: 6 (2.8%), CRITICAL: 101 (47%), MODERATE: 5 (2.3%).
