Do I need an account or an API key?

No. The snippet is plain HTML and the widget is a page on noscere.co that renders itself. There is nothing to sign up for and nothing to configure.

Will it slow my site down or track my visitors?

It loads lazily in an iframe, sets no cookies, and runs no analytics on your readers. It is a rendered page, not a script running inside yours.

Why is the height fixed?

An iframe does not grow to fit what is inside it. Each widget therefore has a height per shape, and the snippet already carries the right one. If you change it, expect either a scrollbar or empty space.

Can I remove the credit link?

Please do not. The link is the whole price of the widget, and it lives outside the frame because that is the only place a link actually counts as a credit.

For site owners

Free widgets for your site

Astrology you can drop into a sidebar, drawn from real ephemeris data rather than stock icons and updating on its own. Pick a widget, a language and a look, copy two lines, done.

Widget

Your code

<iframe src="https://noscere.co/embed/en/moon-today" title="Moon phase by noscere" width="100%" height="400" style="border:0;max-width:340px" loading="lazy"></iframe>
<p style="margin:6px 0 0;font:12px/1.4 system-ui,sans-serif"><a href="https://noscere.co/en/calculators/moon-phase?ref=embed">Moon phase by noscere</a></p>

The credit line sits outside the frame on purpose — that is the part that actually points back to us. Please leave it in.

How it works

Choose the widget, then the language, colour and shape that suit your site.
Copy the snippet and paste it wherever you edit HTML: a sidebar, a page, a widget block.
Nothing else to do. The widgets re-read the sky on their own.

What it costs you

Nothing, and there is no catch worth hiding: the second line of the snippet credits noscere with a link. Keep it and the widgets are yours to use for as long as you like. They set no cookies and track none of your readers.

What the numbers mean

Where a widget names a sign, it means the tropical, geocentric one: the convention most Western astrology uses. Sidereal astrology measures from the fixed stars instead and will name a different sign for the same planet, so the card says which frame it is using rather than letting your readers assume theirs. Dates and times are UTC, and the cards are rebuilt hourly, so the Moon, which moves fastest, can sit up to half a degree behind a chart calculated on the spot.
