Company financials from SEC filings. Every figure links to its filing.

The Belfort Data API returns figures taken only from the filings companies make with the SEC. Each one names its filing, the value first reported and anything we adjusted. A figure our rules can’t settle is left out, not guessed.

Apple’s revenue for fiscal 2025, as the API returns it (shortened) and as Apple’s annual report states it. Open filing_url and the number is there.

What the API serves today. Freshness from the live status route.

Figures current to 7 Nov 2026. Statements current to 7 Oct 2026, the SEC’s latest quarterly data set.

Each figure carries what you need to check it.

The fields below come back on every financial figure, so you can match it to the filing yourself, or have your agent do it.

source: The filing the figure comes from: its form, the date it was filed, and a link to it on the SEC’s site.
first_reported: The value the first filing for this period reported. When a later filing restates it, you get both numbers.
adjustments: Anything we did beyond copying one filed number, such as taking another filing’s figure when one was filed a thousand times too large. Empty when we changed nothing.
null: A value the filing leaves blank comes back as null, never as zero.
Left out: When filings disagree and our rules can’t settle which is right, the figure is left out of the series and the response says so. A call where every figure was left out is free.

Error rates, measured and published.

We checked the newest figure for 100 companies, chosen by hash, against the filing’s own page. A zero in a small sample is not a zero rate.

Checked on snapshot metrics-7141c1f133996c9c. The API serves newer data now. This table changes when the next measurement runs, not with each data load.

Weighted by how many banks (571), insurers (141) and other companies (5,826) file. Ranges are 95% Wilson intervals: a zero in a small sample is not a zero rate.

Bank revenue. Where a bank files no total revenue line, we return total interest income, the top total on its statement. Counting those as wrong too gives 16 of 27.

Not yet checked. No person has read our statements against the filings line by line. These checks test which figure we chose, not whether a company’s own numbers are right. Method and every grade

Questions.

Where do the figures come from?: Only from the filings companies make with the SEC. No other data vendor, no estimates.
What happens when a company restates a figure?: You get the current reading, and first_reported keeps the value first filed for that period. Older readings aren’t kept as versions.
Can I show these figures in my own app?: Yes, with the line “Data: Belfort Research, from SEC filings”. Reselling or redistributing the data itself needs a license.
Is there an uptime guarantee?: Not during the pilot. The status route shows how fresh each dataset is.
Who sells it?: Belfort Research. The terms are in the API terms, which anyone can read before signing up.
Is this investment advice?: No. It is data taken from public filings. The SEC does not endorse it and we are not affiliated with the SEC.
