Usage Notes

Responses reflect the currently tracked records in the repository.
Round responses include an explicit currency. Company and investor aggregate fields are legacy face-value totals and should not be treated as normalized USD when their underlying rounds use multiple currencies.
If you use this data on your website or in an application, a link back to aifunding.me is appreciated.
