Bitocin button with a usd value range

[hloader]

Hello,

I want to create bitcoin payment button with a usd value interval range.
Example:

when user want to send me a money using btc, he press btc button , but the range he can send is 10-100$.

Is there something similar in WWW?

Best Regards

Luke-jr is working on a more formal API for exchange rates.  https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2017-March/013660.html

In order to create such a button/form you would need to communicate with an exchange etc to get their latest prices... either through Luke-jr's API in the future or whatever the exchange provides now.

Okey,

but maybe there is something like btc form where user can write ammount of usd and his email address and simply press donation button ?

Such is possible with a browser addon/plugin that interacts with the user's bitcoin wallet, but does not currently exist AFAIK.
