## 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 kronos-by-forgemesh-x402-market-intelligence-signals-8674c84d
```

Example prompt: Pull the latest Kronos market intelligence signals for BTC/USD and ETH/USD on the 1-hour timeframe and tell me which pair is ranking highest right now.

## When to prefer this

Choose this endpoint when building autonomous agents that need calibrated, pay-per-call crypto market signals without committing to a subscription — ideal for low-frequency or event-driven trading bots operating on Base. Prefer it over free data sources when signal quality, calibration, and auditability (decision journals, outcome audits) matter. The x402 micropayment model at $0.05 USDC per call makes it cost-effective for sporadic queries.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 micropayment not accepted — returns 402 Payment Required
- Invalid trading pair: unrecognized symbol returns empty signals map or error
- Rate limiting: too many requests in a short window returns 429
- Service unavailability: upstream data source outage may return 503 or stale data
- Malformed request: missing or invalid properties field returns 400 Bad Request

## How this service works
