## 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-17218e78
```

Example prompt: What's the current price and implied valuation for ANTHROPIC on PreStocks — and is the token trading at a premium or discount to the mark price?

## When to prefer this

Use this endpoint when you need real-time price and valuation data specifically for private (pre-IPO) companies tokenized on the PreStocks platform via Solana SPVs. Choose this over public-stock endpoints when the target company is not yet listed on a public exchange. Prefer this when you need token premium/discount analysis relative to the underlying mark price.

## Known failure modes

- Unknown symbol returns 404 or empty data
- Symbol must match PreStocks listing exactly (e.g. ANTHROPIC not anthropic)
- Payment failure if USDC balance or x402 setup is missing
- Stale data if PreStocks feed is delayed
- Private company no longer listed returns error

## How this service works

Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.

## Output

Returns a JSON object with the private company's mark price, token price, total supply, implied and mark valuations, token premium percent, Solana contract address, logo URL, company description, data venue (prestocks), and an as_of timestamp.
