## 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 x402stock-us-stocks-endpoint-4416abe1
```

Example prompt: Can you pull the latest market data for NVDA from x402stock? I want to see current price and any available fundamentals.

## When to prefer this

Choose this endpoint when you need US stock or ETF market data without a long-term API subscription, especially in an agentic context where autonomous pay-per-request USDC payments via x402 are acceptable. Ideal for AI agents that need occasional equity lookups without account setup overhead.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Insufficient USDC balance causes payment failure and request rejection
- Ticker not listed on a US exchange may not be supported
- Rate limiting or network issues may cause transient failures
- Malformed properties parameter may return unexpected data subsets

## How this service works

Tokenized-equity (xStocks) on-chain prices vs. underlyings, with premium.

## Output

Returns market data for the requested US stock or ETF ticker, including price, quote, and any available fundamental or descriptive fields, delivered as a JSON response after a per-request USDC payment via x402 protocol.
