## 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 x402-coinopai-com-7bf7e281
```

Example prompt: Before making a trade decision, run a Kronos preflight check on BTC to see if conditions are currently allowed — check the market state, cooldown status, and any signal strength warnings.

## When to prefer this

Use this endpoint as the mandatory first step before calling /kronos/decision. It gates the trade loop by checking real-time market state, cooldowns, and signal conditions so that downstream decision calls are only made when conditions are valid. Prefer this over jumping straight to a decision endpoint when you want to avoid wasted spend on blocked trades.

## Known failure modes

- Missing or invalid symbol parameter returns an error
- Market data unavailable may return allowed:false with a warning
- Payment failure (x402) if USDC not provided
- Rate limiting if called too frequently without cooldown respect
- Symbol not supported returns an error or empty result

## How this service works

Kronos by ForgeMesh crypto market preflight for one symbol. Returns an allowed flag, market and risk state, cooldown status, directional bias, and warnings before a costlier decision call.

## Output

Returns a JSON object with allowed (true/false), market_state (e.g. NORMAL/HALTED/COOLDOWN), cooldown information, signal strength score, and any warnings that would block or caution against trading the requested symbol.
