## 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-carbon-cashmere-de-8e730b20
```

Example prompt: What market regime are we in right now, and can you show me the regime history and transitions for the last 30 days — I want to see how much time was spent in each phase like accumulation, markup, distribution, or crisis?

## When to prefer this

Use this endpoint when you need structured, ML-derived market regime classifications over time rather than raw price or indicator data. Ideal for regime-aware strategy switching, macro-regime backtesting, and market-structure monitoring. Prefer over generic price feeds when you need categorical regime labels (accumulation through crisis) and transition calendars with percentage breakdowns.

## Known failure modes

- Invalid days parameter (outside 1-90 range) returns error
- Missing or malformed query parameters return 400-level errors
- Payment not provided or insufficient USDC (x402 payment required at $0.02 per call)
- Downstream ML detector outage may cause stale or empty series
- Rate limiting if called too frequently without proper payment headers

## Output
