## 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 agents-x402stock-xyz-prestocks-private-company-valuation-by-symbol-59c38c70
```

Example prompt: What's the current valuation and PreStocks token price for OPENAI right now — is the token trading at a premium or discount to the SPV mark?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time pricing and valuation data for a specific private, pre-IPO company that is tokenized on Solana via PreStocks SPVs. Ideal when you need both the SPV-backed fundamental mark and the secondary market on-chain price in a single call, including the premium/discount spread. Use the /api/v1/private-stocks listing endpoint first if you need to discover available symbols.

## Known failure modes

- Unknown or unsupported symbol returns a 404 or error response
- Mark price may be stale if the SPV has not been recently updated by the fund administrator
- On-chain token price may be null if there is no recent trade liquidity
- Token supply may be null for newly issued tokens
- Payment failure (402) if USDC balance is insufficient for the $0.01 per-call fee

## 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
