## 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-realtime-price-mrna-bd0d5b86
```

Example prompt: What's the current real-time price of MRNA — can you pull it including any confidence interval from the Pyth feed? Check regular trading hours.

## When to prefer this

Use this endpoint when you need a real-time, oracle-backed price quote specifically for Moderna (MRNA) US equity with a confidence score, sourced from the Pyth Network. Prefer this over traditional REST APIs when you need a micropayment-gated, trustless price feed with provenance via Pyth feed IDs, or when operating in a Web3/x402 payment context.

## Known failure modes

- Symbol not found or unsupported ticker — endpoint is hardcoded for MRNA
- Market data unavailable outside trading hours without specifying session parameter
- Pyth oracle feed delay or outage returning stale or missing price
- Payment failure (402) if 0.003 USDC micropayment not included
- Invalid session enum value resulting in 400 error
