## How to call it through Zero

```sh
zero fetch --capability blockrun-gld-realtime-price-783c4e19
```

Example prompt: What is the current real-time price of GLD right now during regular market hours, including the confidence interval from the Pyth feed?

## When to prefer this

Use this endpoint when you need real-time, high-frequency price data for the GLD ETF (SPDR Gold Shares) specifically, backed by Pyth Network oracle feeds with a confidence score. Ideal for agents that need gold-price exposure via an equity vehicle with sub-cent micropayment pricing ($0.001/call). Prefer over manual scraping or delayed data sources when freshness and confidence intervals matter.

## Known failure modes

- Invalid or unsupported ticker symbol returns an error — GLD is the hardcoded symbol for this endpoint
- Invalid session enum value (not 'pre', 'post', or 'on') returns a 400 bad request
- Service unavailable or Pyth feed timeout during market downtime may return 503
- Payment not included or insufficient USDC (must be $0.001) returns 402 Payment Required
