## 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-qqq-real-time-price-feed-3054c668
```

Example prompt: What is the current real-time price of QQQ, and can you include the confidence interval from the Pyth oracle feed?

## When to prefer this

Use this endpoint when you need real-time or near-real-time price data for the QQQ ETF specifically, backed by the Pyth decentralized oracle network with a confidence score. Prefer this over traditional brokerage APIs when operating in a pay-per-call, crypto-payment (x402) agentic environment and you need a lightweight, low-cost ($0.001 per call) price lookup with provenance metadata (feed ID, publish time).

## Known failure modes

- Market closed and no session parameter specified — may return stale or unavailable price
- Invalid session enum value — returns 400 bad request
- Pyth feed temporarily unavailable — service may return 503 or degraded confidence
- Payment not provided or insufficient — returns HTTP 402 payment required
- Symbol path mismatch — this endpoint is hardcoded to QQQ; passing other symbols may fail
