## 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 gloom-cds-indexes-api-b2001ed8
```

Example prompt: Can you pull the latest CDS index data from Gloom — I want to see the current CDX IG spread level, today's change, and the maturity date?

## When to prefer this

Choose this endpoint when you need structured, programmatic access to CDS index spread data (especially CDX IG) for credit market analysis, risk monitoring, or fixed income research. Prefer over manual data sources or Bloomberg terminals when you need machine-readable credit derivative index data in a lightweight API format with per-call micropayment pricing.

## Known failure modes

- Invalid or unsupported properties filter returns empty data array
- Payment failure (402) if USDC payment not included or insufficient
- Rate limiting or service unavailability returns 5xx error
- Stale or delayed data if market feed is lagging
