## 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 blockrun-us-stock-price-real-time-pyth-feed-d6032818
```

Example prompt: What's the current price of AAPL during regular trading hours? I need the Pyth-sourced quote with the confidence interval.

## When to prefer this

Choose this endpoint when you need real-time US equity prices sourced from the Pyth Network oracle with a confidence score, require no long-term API key setup, and want micropayment-per-call billing settled in USDC on Base or Solana. Ideal for AI agents operating autonomously that need verifiable, oracle-backed stock prices without subscription overhead.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error
- Invalid session enum value returns a 400 bad request
- Payment failure (insufficient USDC balance) returns HTTP 402
- Network or Pyth oracle downtime may result in stale or unavailable price data
- Pre/post-market session requested outside valid hours may return no data
