binlist.net is a public web service for looking up credit and debit card metadata.
The first 6 or 8 digits of a payment card number (credit cards, debit cards, etc.) are known as the Issuer Identification Numbers (IIN), previously known as Bank Identification Number (BIN). These identify the institution that issued the card to the card holder.
Requests are throttled at 10 per minute with a burst allowance of 10. If you hit the speed limit the service will return a 429 http status code.

The aim of this database is explicitly not to provide up-to-date fundamentals or stock data as those can be obtained with ease (with the help of this database) by using FundamentalAnalysis or yfinance.

With this information, you can analyse specific areas of the financial world and/or find that product that is hard to find. See for examples on how you can combine this database and the earlier mentioned packages the section Examples.

Cryptocoins "minted" are based upon the amount of bandwidth and CPU time your systems donate to the Bitcoin network.
