## 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-stock-valuations-e8e5c932
```

Example prompt: What's the current pre-IPO valuation and on-chain token price for OpenAI via PreStocks — is the token trading at a premium or discount to the SPV mark price right now?

## When to prefer this

Use this endpoint when you need current valuation and pricing data for specific pre-IPO private companies that have associated PreStocks Solana SPV tokens. It is uniquely suited for comparing SPV mark valuations against live on-chain token prices to detect arbitrage or sentiment signals. Prefer this over generic private market data sources when you need both the off-chain SPV reference price and on-chain token market data in a single call.

## Known failure modes

- Unknown or unsupported symbol returns a 404 or error response
- Symbol provided in wrong case or format may not resolve
- Stale SPV mark price if the SPV has not been recently updated
- Network or RPC issues with Solana may cause token price retrieval failures
- Payment of $0.01 USDC not fulfilled results in 402 Payment Required

## How this service works

The current valuation of one private, pre-IPO company by symbol — e.g. ANTHROPIC, OPENAI, SPACEX, ANDURIL, NEURALINK, KALSHI, POLYMARKET — via its PreStocks Solana token, backed 1:1 by SPV exposure. Returns the SPV mark price and valuation, the on-chain token price and implied valuation, the token's premium/discount, supply, and contract. List them all at /api/v1/private-stocks. From x402stock

## Output

A JSON object containing the SPV mark price and valuation, the on-chain Solana token price and implied valuation, the token's premium or discount relative to the SPV mark, the circulating token supply, and the on-chain contract address — all for the requested private company symbol.
