## 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 financial-data-x402-stock-quote-8216dd70
```

Example prompt: What is the current stock price of AAPL, including today's high and low, volume, and 52-week range?

## When to prefer this

Choose this endpoint when you need frictionless, pay-per-call stock quotes with no API key registration or subscription — ideal for low-frequency lookups, agent pipelines, or scenarios where you want to pay only for what you use in USDC. Prefer it over subscription-based data providers when cost predictability at micro-scale matters or when operating in a crypto-native environment using the x402 payment protocol.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty response
- Payment failure (insufficient USDC balance or network issues) causes a 402 response blocking data delivery
- Market closed or pre/after-hours data may reflect stale or delayed prices
- Rate limiting or network timeouts on Base or Solana payment rails delay the call
- Ticker format mismatch (e.g. using exchange-prefixed symbol instead of bare ticker)

## How this service works

Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
