How this service works
Finviz quote snapshot for one stock ticker: the key statistics table as label and value pairs (market cap, P/E, price, change, volume and similar), read from the public quote page. Values are as Finviz shows them, possibly delayed.
Output
Returns a JSON object with the stock symbol, a source URL pointing to the Finviz quote page, a checkedAt timestamp, and a fields object containing financial data such as Market Cap, Enterprise Value, Sales, Income, Book/sh, Cash/sh, Employees, IPO date, and Index membership.
Example use cases
Stock research before earnings
“Grab the Finviz fundamentals for NVDA — I want the market cap, enterprise value, sales, income, and how many employees they have right now.”
Index membership check for portfolio
“Can you tell me whether MSFT is in the S&P 500, and also pull its book value per share and cash per share from Finviz?”
IPO date and basic stats lookup
“Look up TSLA on Finviz — I need its IPO date, current market cap, and revenue figures.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/finviz?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, no-signup access to Finviz-sourced stock fundamentals (market cap, revenue, income, index membership, employees) for a single equity ticker without maintaining an API key. It is well-suited for AI agents that need lightweight per-call financial enrichment billed via crypto micropayment (x402/USDC). Prefer alternatives like a Bloomberg or financial data API if you need historical time series, real-time price quotes, or institutional-grade data reliability.
Side effects
- Invalid or unknown ticker symbol returns an error or empty fields
- Finviz rate limiting or page structure changes may cause parsing failures
- Delisted or OTC-only tickers may not be available on Finviz
- Network timeout from the upstream Finviz page fetch
- Missing fields if Finviz does not publish certain data for small-cap or foreign stocks
