FAQ
Is it free?
Yes. The widgets are free for personal and commercial use. We only ask that you keep the credit link to ValorFinal that comes with the code.
Do I need an account or a plugin?
No. Each widget is a standard iframe. There is no signup and no plugin to install.
Will it slow my website down?
No. The iframe loads lazily and the data comes from our server, so it adds almost no weight to your page.
Can I match my site's design?
Yes. In the widgets catalog you can choose a light or dark theme, an accent color and the width before copying the code.
Which currency are the rates in?
Quotes are in Brazilian real (BRL). The USD and EUR rates use PTAX from the Central Bank of Brazil.
Values are informational and do not constitute advice. The full Portuguese catalog is available at valorfinal.com.br/embed.
