## 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`):

Example prompt: Pull the historical price-path analogs for BTC-USD from Kronos so I can see which past market cycles most closely match current conditions and get a multi-timeframe forecast signal.

## When to prefer this

Use this endpoint when you need historically-grounded price-path forecasting for crypto assets, commodities, or pre-market equities — specifically when you want to identify past market cycles that are statistically similar to current conditions. Prefer it over generic price feeds when the goal is pattern-matched analog-based forecasting rather than raw price data or sentiment analysis.

## Known failure modes

- Invalid or unsupported symbolKey returns a 404 or error response
- Payment failure via x402 USDC micropayment blocks access and returns 402
- Stale or missing data for low-liquidity symbols may yield sparse analog sets
- Rate limiting or quota exceeded returns 429
- Network timeout if market data pipeline is delayed
