Company Profile

Put Quant500 data on your site

Two free widgets, no sign-up and no cost, to paste into a blog, a forum or a newsletter. They carry no JavaScript, set no cookies and track nobody: each one is an HTML page inside an <iframe> weighing under 15 KB that follows the reader's light or dark theme.

Swap the symbol in the URL for any S&P 500 company (say AAPL, MSFT or KO), and ?lang=es or ?lang=en picks the language.

1. When does it report? (NVDA)

The date the company has already announced and, below it, what its SEC 8-K filings say: which session its recent announcements fell in, what time the filing reached EDGAR, and how much the stock moved close to close. That last figure is what already happened; it is not a forecast or a recommendation.

Code to copy:

<iframe src="https://quant500.com/widget/resultados/NVDA?lang=en"
        title="NVDA next earnings date"
        width="100%" height="260" loading="lazy"
        style="border:0;max-width:420px" scrolling="no"></iframe>
<p style="font-size:12px"><a href="https://quant500.com/earnings-date/NVDA">NVDA earnings dates on Quant500</a></p>

2. Insider buying, 30 days (JPM)

Open-market buys and sells reported by insiders on Form 4, with the dollar amount and the count over the last 30 days with data. Transfers between accounts of the same insider are excluded.

Why the snippet has a link under the iframe

A link that lives inside an <iframe> does not count as a link from the page that embeds it: to a browser and to a search engine it is a separate document. That is why the snippet is two things, the widget and a plain paragraph link below it. That paragraph is the attribution, and it is the only thing we ask in return. Remove it and the widget still works, but then this stops being a trade and becomes a free service we pay for.

The same thing in JSON

The same URLs return JSON when requested with Accept: application/json, or by adding &format=json. They carry Access-Control-Allow-Origin: *, so a browser can read them.

curl -H "Accept: application/json" \

Licence and limits

  • Free to use, commercially too, on any website, with no permission and no account.
  • Keep the attribution: the "Data: quant500.com" footer inside the widget and the link below it.
  • Data derived from SEC filings (8-K and Form 4) is published under CC0 1.0. Cite it, rebuild it, republish it.
  • Do not alter the figures and do not present the widget as yours or as another brand's.
  • Content updates on our server: there is nothing to maintain on your side. Each response may be cached for five minutes.
  • Reasonable use: this is built for pages, not for scraping. If you need the data in bulk, there are complete free CSV files on Open data.
  • This is not financial advice and not a buy or sell recommendation. These are facts that already happened, each with its SEC filing behind it.
