## 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 us-stock-price-lookup-086c39c9 -d '<json body>'
```

Example prompt: What's the current stock price for NVDA on the US market?

## When to prefer this

Use this endpoint when you need to look up the current price of a US-listed stock (NYSE, NASDAQ, etc.) by ticker symbol and are operating within an x402-compatible payment flow. Prefer this over web-scraping or free alternatives when you need reliable, structured, paid API access with per-call micropayment billing via USDC.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Payment failure (insufficient USDC balance) blocks the request
- Market hours may affect real-time vs delayed pricing
- Rate limiting if too many requests in quick succession
- Unknown US exchange ticker returns a failed job status
