## 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 stock-price-lookup-via-x402-paywall-a4e749fb
```

Example prompt: What's the current price of AAPLx right now? I need the live quote for the tokenized Apple stock.

## When to prefer this

Choose this endpoint when you need quick, pay-per-call stock or tokenized-stock price lookups without a subscription, especially when operating in a crypto-native or x402-compatible payment environment. It is well-suited for agents that only occasionally need price data and want to avoid recurring API key costs. It supports tokenized equity symbols (e.g. AAPLx, TSLAx) which traditional stock APIs may not cover.

## Known failure modes

- Missing or invalid symbol parameter returns an error
- Payment failure (insufficient USDC balance or x402 handshake error) blocks access
- Symbol not supported returns empty or error response
- Chain parameter mismatch may return no data
- Service downtime on Render hosting may cause 502/503 errors
