## 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 cmc-regime-classification-strategy-spec-api-56548409
```

Example prompt: What's the current market regime classification and strategy spec for Bitcoin (CMC coin ID 1) right now?

## When to prefer this

Use this endpoint when you need a structured, pay-per-call market regime label and associated trading strategy spec for a specific cryptocurrency identified by its CoinMarketCap ID. Prefer this over general market data APIs when you specifically need a regime classification (bull/bear/sideways/etc.) paired with a strategy recommendation, rather than raw price or OHLCV data.

## Known failure modes

- Missing or invalid CMC coin ID returns an error or empty response
- Unsupported coin ID (not BTC/ETH/BNB or similar known coins) may return an error
- Payment failure via x402 protocol results in 402 Payment Required with no data
- Malformed GET request without required id query param returns validation error
- Transient upstream CMC data unavailability may cause stale or failed classification

## How this service works

CMC regime classification + strategy spec (USDC pay-per-call)

## Output

Returns a JSON object containing the regime classification string (e.g. 'bull', 'bear', 'sideways'), the coin's symbol, its CMC coin ID, and a strategy_spec object outlining the recommended trading strategy for that regime.
