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

Endpoint
GEThttps://agents.x402stock.xyz/api/v1/private-stocks/{symbol}When to prefer
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.

- On-chain token price may be null if there is no recent trade liquidity
