## 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-private-stocks-data-1dddf7f8
```

Example prompt: Can you pull up the latest private stock data for SpaceX — I want to see whatever market and financial metrics are available?

## When to prefer this

Use this endpoint when you need financial or market data specifically for private (non-publicly-traded) companies or pre-IPO securities. Choose this over the public stock endpoints when the target company is not listed on a public exchange. Prefer this when building private equity research tools, pre-IPO investment trackers, or alternative investment platforms that need private market data without API keys or subscriptions.

## Known failure modes

- Invalid or unrecognized private stock ticker returns an error or empty result
- Payment failure if insufficient USDC balance causes request to be rejected
- Properties filter with unsupported fields may return partial or no data
- Private company data may be stale or unavailable if not recently reported
- Rate limiting if too many requests are made in rapid succession

## How this service works

Returns prices for pre-IPO private companies like Anthropic, OpenAI, SpaceX, etc.

## Output

Returns private stock market and financial data for the requested company or ticker, including available pricing, valuation metrics, and other financial properties as reported for private/pre-IPO securities. Charges $0.02 USDC per call via x402 micropayment.
