## 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 quantx402-track-record-api-0c939444
```

Example prompt: Pull the QuantX402 track record for BTC-USD so I can see how accurate the Kronos directional forecasts have been — I want to know the scored count and total forecasts before I start relying on the signals.

## When to prefer this

Choose this endpoint when you need to audit or validate the historical accuracy of QuantX402's Kronos directional forecasts before committing to live signal usage. It is the best choice for due-diligence workflows, backtesting audits, or trust-building checks on AI-generated market signals — especially for BTC-USD and other crypto assets where live data is available. Not suitable for real-time price feeds or live signal generation (use sibling endpoints for those).

## Known failure modes

- Payment not completed via x402 — returns 402 Payment Required
- Symbol not yet supported (stocks/forex still rolling out) — may return empty or null data
- direction_hit field may be null for unresolved/future forecasts
- scored count of 0 indicates no resolved forecasts yet for that symbol
- Stale or cached data if market data pipeline is delayed

## How this service works

Track Record: every stored Kronos signal and its scored outcome, misses included (the signal+outcome dataset). Pay per call via x402. Not financial advice.

## Output

Returns a JSON object with two main sections: 'recent' (a list of recent forecast entries per symbol including as-of timestamp, direction called, and whether the direction hit) and 'summary' (aggregated stats per symbol including total forecasts and scored count). Useful for evaluating signal quality before trading.
