API3 and Why it Matters
API3 is a technology which provides a decentralized solution for APIs to directly deliver data to blockchain applications. This leads to improvement in the overall security and reliability of data feeds.
API stands for Application Programming Interface. So API3 is just an API for Web3.
Traditionally, an application is any software with a distinct function. Interface is a contract of service between two applications. This contract defines how the two communicate with each other using requests and responses.
An API is a set of rules or protocols that enables software applications to communicate with each other to exchange data, features and functionality.
API3 introduces a decentralized solution known as Decentralized APIs (dAPIs). These dAPIs function as secure data feeds, directly connecting blockchains with the data they need from the real world. Unlike centralized oracles, dAPIs eliminate the need for a trusted intermediary, giving way to a more secure and transparent data ecosystem.
API3 matters because it provides the much needed data access which is essential because smart contracts, the self-executing agreements that power decentralized applications (dApps), rely on information from the external world to function effectively.
This data, encompassing everything from weather updates to financial market prices, is vital for smart contracts to execute their programmed tasks.
Traditional methods of feeding data into blockchains present limitations. Centralized oracles, third-party services that bridge the gap between blockchains and external data sources, introduce a single point of failure. If a centralized oracle is compromised, the entire system's security and reliability can be jeopardized.
Additionally, centralized oracles raise concerns about data manipulation and lack of transparency.
As a result of its reliable and decentralized data access for smart contracts, API3 plays a critical role in shaping the future of Web3.
Web3, the next iteration of the internet, promises a more decentralized and user-controlled online experience. API3 empowers developers to build secure and innovative dApps that leverage real-world data, unlocking the true potential of Web3 and its applications.
The three core components of API3 - Airnode, dAPI, and DAO - are named after Norse mythological beings: Airnjörd (god of the sea and air), Dellingr (dawn personified), and Dís (goddesses associated with fate).

The Core Functionalities of API3
The core functionalities of API3 can help you to better understand the technology. Here are some of them:
Airnode
Airnodes are like the bridge between blockchains and APIs. They are the cornerstone of the API3 ecosystem. They bridge the gap between isolated blockchains and traditional APIs, supplying smart contracts with essential real-world data.
How Airnodes Work
Consider Airnodes as software programs deployed by API providers. These providers, the entities with access to valuable data, configure Airnodes to securely connect to their APIs. When a smart contract on a blockchain requires specific data, it sends a request to a designated Airnode.
The Airnode then acts as a middleman:
- Retrieving Data: The Airnode securely fetches the requested data from the API provider's system.
- Security Checks: Airnodes perform essential security checks on the retrieved data to ensure its integrity and validity before relaying it further.
- Delivering Data: The validated data is then delivered to the requesting smart contract on the blockchain.
This entire process is transparent and verifiable, as the communication between Airnodes, smart contracts and the blockchain is recorded on the blockchain ledger.
Benefits of Using Airnodes
There are several advantages to utilizing Airnodes for data retrieval in smart contracts:
- Decentralization: Airnodes eliminate the need for centralized oracles, fostering a more secure and trustless environment. There's no single point of failure, as multiple Airnodes can service the same data request.
- Enhanced Security: Airnodes perform rigorous security checks on retrieved data, mitigating the risk of manipulation or tampering before it reaches the smart contract.
- Flexibility: Airnodes can be configured to connect with various APIs and data sources, offering developers a wider range of data options for their smart contracts.
- Cost-Effectiveness: Requesters (smart contracts) cover the gas costs associated with Airnode operations, ensuring a fair and sustainable economic model.
Decentralized APIs (dAPIs)
Traditional APIs act as intermediaries, allowing applications to communicate and exchange data. However, in the context of blockchains, traditional APIs have limitations. They are often centralized, raising concerns about data manipulation and single points of failure.
This is where dAPIs, a core innovation of API3, come into play.
dAPI vs Traditional APIs: Key Differences
Here's a breakdown of the key differences Decentralized APIs (dAPIs) vs Traditional APIs:
