## When to prefer this

Use this endpoint when you need to audit or validate the reliability of Kronos's forecast signals before committing to paid prediction calls, or when periodically benchmarking model performance for crypto, commodities, or pre-market equities signals. Prefer this over the forecast endpoints themselves when the goal is evaluation rather than prediction.

## Known failure modes

- Endpoint unavailable: service downtime returns 503

- Authentication issues with x402 payment header formatting
