About India Stack
- It is a set of Application Programming Interface (APIs) that allows governments, businesses, startups and developers to utilise a unique digital Infrastructure.
- India Stack consists of three layers of open APIs: identity, payments, and data.
- Although the name of this project bears the word India, the vision of India Stack is not limited to one country.
- It can be applied to any nation, be it a developed one or an emerging one.
- The four distinct technology layers provided are
- Presenceless layer: Where a universal biometric digital identity allows people to participate in any service from anywhere in the country.
- Paperless layer: Where digital records move with an individual’s digital identity, eliminating the need for massive amount of paper collection and storage.
- Cashless layer: Where a single interface to all the country’s bank accounts and wallets to democratize payments.
- Consent layer: Which allows data to move freely and securely to democratize the market for data?
- Some of the APIs that are a central part of India Stack: Aadhaar Proof, Aadhaar e-KYC, e-Sign, Digital Locker, Unified Payment Interface.
Q1) What is API?
It stands for Application Programming Interface. In the context of APIs, the word Application refers to any software with a distinct function. Interface can be thought of as a contract of service between two applications. This contract defines how the two communicate with each other using requests and responses.
