## 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-quote-via-pyth-54fecea0
```

Example prompt: What's the current price of NVDA stock right now, including pre-market session data and the confidence score?

## When to prefer this

Use this endpoint when you need real-time US equity prices sourced from the Pyth oracle network without managing traditional API keys, and when you want pay-per-call micropayment billing settled in USDC on Base or Solana. Ideal for AI agents that need low-friction, on-demand stock price data with cryptographic provenance (feed ID, publish time, confidence interval) rather than a subscription-based data feed.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error or empty result
- Invalid session enum value (not pre/post/on) causes a 400 bad request
- Payment failure (insufficient USDC balance) returns HTTP 402 Payment Required
- Pyth oracle temporarily unavailable causes a 503 or stale data response
- Rate limiting or gateway overload may return 429 Too Many Requests
