Astra
Astra (Astra Finance, Inc.) is a financial technology company providing an all-in-one instant payments API that lets product teams embed real-time money movement between bank accounts and debit cards.

Astra publishes 8 API contracts indexed on the APIs.io network, including Accounts API, Authorization API, Cards API, and 5 more. Tagged areas include Company, Payments, Fintech, Money Movement, and ACH.
