## How to call it through Zero

```sh
zero fetch --capability blockrun-klac-real-time-stock-price-bdfdddf8
```

Example prompt: What's the current real-time price of KLAC stock right now, including confidence interval? Use Pyth-sourced data.

## When to prefer this

Use this endpoint when you specifically need a real-time Pyth oracle-sourced price for KLAC (KLA Corporation) with a confidence interval — particularly useful in DeFi, on-chain, or agentic financial workflows where Pyth feed provenance and feed ID traceability matter. Prefer over generic market data APIs when you need cryptographically-sourced oracle pricing with explicit confidence bounds.

## Known failure modes

- Symbol not found or not supported — returns error if ticker is not available on Pyth
- Market closed with no session parameter — may return stale or unavailable price outside trading hours
- Invalid session enum value — returns validation error if session is not 'pre', 'post', or 'on'
- Payment not provided or insufficient — x402 payment required, returns 402 if USDC not supplied
- Network/upstream Pyth feed delay — confidence interval may widen or data may be temporarily unavailable
