Mboum collects market data from third-party sources and processes it before showing it on the site or returning it from the API. Mboum doesn't guarantee that every figure is accurate or complete (see the Terms), so check anything important against company filings or your broker before you act on it.

Every plan, including Free, can call all the market data endpoints, including options. Plans differ by monthly request allowance and by whether commercial use is allowed. Monthly allowances: Free 500, Investor 10,000, Business 50,000, Developer 250,000, Enterprise 2,500,000, and Institutional 5,000,000 requests. Current prices are on the pricing page.

Your card is charged when you subscribe and then at the start of each billing period, monthly or yearly. If you turn on overage, it is charged separately after each monthly usage period ends.

The Developer, Enterprise, and Institutional plans include commercial use. Under the Terms, the Investor plan is for personal use only, and a business can't use a personal plan, even internally, without written approval from Mboum. If you're not sure which plan covers your use, email [email protected] before you subscribe.
