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.
Example use cases
Pre-IPO valuation check for unicorns
“What is SpaceX currently valued at on PreStocks, and how does the token price compare to its mark valuation right now?”
Token premium analysis for OpenAI
“Look up the OpenAI PreStocks token for me — I want to know if it's trading at a premium or discount to the mark price, and by how much.”
Stripe private stock supply lookup
“Can you pull up the Stripe PreStocks token and tell me the total token supply, the current implied valuation, and the Solana contract address?”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/private-stocks/%7Bsymbol%7DWhen to prefer
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.
Side effects
- 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
